General Knowledge of Chinese Ceramics Calcination Technology

Xinxiang custom ceramic mug manufacturer, Ceramic mugs are all made by calcining in a kiln. So how are coffee mugs fired? What effect does the firing process have on ceramic mugs?

Ceramic mugs can actually be divided into three kinds in the firing process. One is a single firing. That is, from the blank clay to our commonly used ceramic coffee mugs, only through the kiln calcination once and molded. The second type is secondary firing. As the name suggests, ceramic mug blanks need to enter the kiln twice for calcination. into the kiln for calcination. The first time is unglazed firing, usually become "plain firing", the purpose is to increase the mechanical strength of the body, not easy to damage. Often larger or thinner bone china cups are often fired twice. After the first firing, the glaze is applied (for information on glazes, please refer to our factory's website). information, please refer to our factory's previous information), and then the second firing. Depending on the type of cup, the material and the glaze, the temperatures of the two firings are different. The third type is the triple firing, which requires three trips into the kiln. Often more complex ceramic pieces only need. The first time is plain firing, the second time is glaze firing, the third time is appliqued or hand-painted and then fired. Then in the firing process, the kiln temperature, oxygen content, heating time and cooling time, what is the impact on the ceramic coffee mug? The following details Introduction:

1. What is the oxidizing flame, reducing flame and neutral flame?

Flame in the kiln at different times have different properties. The nature of the flame can be roughly divided into three categories: oxidizing flame, reducing flame and neutral flame, different properties of the flame has different roles.

1). Oxidizing flame

Refers to the complete combustion of fuel when the flame, the flame must have a large amount of oxygen supply for complete combustion, when the kiln has sufficient oxygen, less CO. In order to make the billet in the moisture and all organic matter are evaporated and volatilized discharge, so that the billet to get the normal contraction, so in the kiln firing There must be an oxidizing flame stage in the process.

2). Reduction flame

Reduction flame is an incomplete combustion flame. At this time the kiln produces a lot of CO and hydrogen, no or very little free oxygen exists. Because the reducing flame can make the embryo body of high-value iron (Fe2O3) to be fully reduced to ferrous oxide (FeO), and become green, to eliminate porcelain Color yellowing phenomenon, so in the kiln firing process of daily-use porcelain, more reduction flame firing.

3). Neutral flame

Burning neutral flame produced in the kiln of carbon monoxide and hydrogen and into the kiln of air compounds almost equal, in a state of equilibrium. Its role is to make Yang ferrous no longer subject to oxidation, and finally make the body to achieve the purpose of complete glass. But control the neutral flame is very difficult However, it is very difficult to control the neutral flame, and it is often used to replace it with a weak reducing flame.

2. How to observe the flame color to determine the temperature and nature?

Ten years ago, Xinxiang ceramic factory is no testing equipment, engineers can rely on the naked eye to observe the flame color to determine the temperature and nature of the flame. This is because the color and concentration of light radiated by hot objects vary with the temperature. What we often see is the initial red flame with a temperature of about 600°C, dark red 700°C, cherry red 800°C, bright cherry red 1000°C, yellowish-white 1300°C, white 1400°C, and so on. This relies on experience to determine the temperature, can make up for each other with the detection equipment, has its irreplaceable.

The nature of the flame, in general, burning billet ceramics, 900 ℃ before the oxidizing flame, in order to prevent soot accumulation in the billet. 1000 ℃ or so is the reducing flame, so that the high value of iron into low value of iron, 1140 ℃ after the use of neutral flame. Five years ago, the plant installed testing equipment, for the The temperature control, oxygen, carbon monoxide detection is more accurate.

3. What is flat-burning insulation?

Flat firing insulation is to maintain a constant temperature for a certain period of time. The purpose is to keep the temperature up and down in the kiln at the same time, with no temperature difference.

1). Flat firing and holding during the dewatering period allows the water in the blank to evaporate safely, the quartz crystals to be transformed safely, and prevents the blank from cracking.

2). The purpose of the flat-firing heat preservation before glaze melting is to make the organic matter contained in the blank fully reacted under high temperature, and the waste gas produced is fully volatilized and cleaned up to avoid blistering of the cup.

3). In the glass stage of flat-firing insulation, so that the billet within the iron trioxide and silicate compounds to generate new substances - mullite, and feldspar and quartz synthesized feldspar glass.

4. What physical and chemical changes occur in the billet during kiln firing?

1). The physical changes that occur in the kiln firing process of the billet:

(1). Weight reduction: the result of evaporation of water, water of crystallization and organic matter in the raw material.

(2). Loss of plasticity.

(3). Change in color.

(4). Changes in voids, the evaporation of water and organic matter is accompanied by a gradual increase in the void ratio within the billet, to the point where glassing begins, the voids are again filled with solution, the particle cups are surrounded by liquid, and the voids are again gradually reduced, until the billet is sintered.

(5). Volume contraction: the volume of the billet is slightly swollen when the void increases, and gradually shrinks when the void decreases.

(6). Mechanical strength changes, the crystal lattice is destroyed, when the water of crystallization is evaporated, the crystals split, the mechanical strength of the billet decreases, to recrystallization, the mechanical strength becomes greater.

2). Chemical changes in the billet: changes such as oxidation and reduction, reduction occurs mostly before 250-900℃, decomposition occurs mostly before 500-1300℃.

(1). Decomposition of carbonate.

(2). Oxidation of carbon, sulfide and organic matter.

(3). The oxidative decomposition of carbonaceous and organic matter present in the billet begins above 600°C and continues to high temperatures, the gas produced at this stage must be completely discharged, otherwise it will cause blistering of the billet. C+O2=C02

(4). Strong reduction stage

This stage of the body of the blank of iron oxide and sulfate in the glaze layer before the closure of the body of the full reduction and decomposition.

(5). Ferrous oxide and silica to produce a glassy substance, promoting the sintering of the body.

5. firing kiln should pay attention to what problems?

1). Too rapid a change of temperature in the kiln will cause the ceramic mug to crack easily.

2). Insufficient oxidizing time and too fast kiln firing will lead to blistering of ceramic cups easily.

3). When the fire of the kiln is not even, it will easily lead to deformation of the body.

4). Uneven temperature in the kiln combined with over-firing will cause the ceramic mug to swell easily.

5). When the firing method and the nature of the flame are not suitable, the surface of the ceramic is easy to change color and produce stains.

6). When the cold kiln is too slow, the ceramic coffee mugs tend to be rough in section.

7). Burning reduction flame should not be too heavy, too long, otherwise the ceramic cup is easy to have soot stains.

6. The technical characteristics of rapid firing kiln

General tunnel kiln cross-section is large, ceramic products are densely stacked, the temperature difference between the various parts of the product is large, so it can not quickly and evenly heat and cool the ceramic products, resulting in a long firing cycle of more than ten hours.

Rapid firing of the kiln performance of the basic requirements are: the ability to uniformly heat and cool products, and can flexibly adjust the temperature and gas. In order to meet this basic requirement, rapid firing kilns have the following characteristics in terms of structure and materials:

1). Small cross-section

In order to achieve uniformity of temperature in the cross-section of the kiln, the cross-section tends to reduce the height and become flat. 1250-1300 ℃ fired ceramic mugs, the firing cycle requires only 60-90 minutes.

2). Low sulfur content

Rapid firing is best used in open flame direct heating, the fuel used requires no will, low sulfur content, such as natural gas, liquefied petroleum gas, light oil, etc.. The sulfur content of the fuel for open flame firing should be 0.2%.

3). High-speed nozzle

High-speed nozzle has three advantages, fast combustion speed, strong space heat, and uniform temperature distribution. High-speed nozzle is an important technology to reduce the temperature difference in the kiln and realize rapid firing.

4). High quality kiln construction materials

In order to make the kiln temperature can be adjusted flexibly according to the requirements of the temperature curve. The kiln construction materials should be lightweight heat-resistant materials and lightweight insulation materials with low thermal conductivity, small thermal fusion, and certain strength.

5). Reduction of kiln furniture

In rapid firing, the kiln should be minimized or not used. A single layer is used to place the product. Elimination of kiln furniture improves heat transfer efficiency and flexibility of the kiln.

6). Advanced Conveying Methods

The general tunnel kiln uses bulky kiln cars to convey the billet, the kiln car heat storage is large, easy to cause the ceramic mug manufacturers heating and cooling lag, not suitable for rapid firing. Conveying methods for rapid firing include walking beam, pushing plate, roller conveyor, etc.

Characteristics of bone china mugs, identification, maintenance and the difference with porcelain

Xinxiang custom ceramic mug manufacturer, Bone china, the basic process is to animal bone charcoal, clay, feldspar and quartz as the basic raw materials, after high-temperature firing and low-temperature glaze fired twice made of a kind of porcelain. The two basic features of bone china are the essential basis for distinguishing bone china from other porcelains. Characteristic one: bone charcoal content of 36% or more (national standard); Characteristic two: after the second firing and become (plain firing, glaze firing). According to the bone china standard set by the United Kingdom, contains thirty percent from animal bones in the tricalcium phosphate, and the finished product has a light transmittance, to be called bone china. In the United States, the standard is at least 25%.

1. History of bone china

Bone china was first produced in England, invented around 1800. Bone china invention course is quite comical, began to Thomas Frye (Thomas Frye) in the manufacturing process accidentally mixed with animal bone powder, after Josiah Spode (Josiah Spode) continue to study and get, the earliest its basic formula is six parts of bone powder and four parts of the stone, but gradually developed into fifty parts of the bone powder and twenty-five parts of the stone and twenty-five parts of the clay, until today in the England has been recognized as the standard recipe. Over the past two hundred years, bone china through generations of master craftsmen's hands, gradually developed into the world's ceramic treasures.

The production of bone china began in England, but who actually made the first bone china is still not conclusive, the academic community generally believe that the first successful production of bone china in England is Josiah Spode (Josiah Spode) (1755-1827). Josiah Spode Josiah Spode made bone china by combining calcined Josiah Spode mixed calcined bone directly with china clay and mineral fluxes to become the traditional raw material for hard porcelain, which he successfully tested in the early 19th century. He then began a systematic study of formulas for the production of bone china, and by the end of 1821, the ratio of bone ash to china stone was "standardized", when feldspar was thought to be the most important raw material. At that time, it was believed that feldspar as a flux containing bone ash 46% of the blanks produced porcelain is the best product. After a long period of exploration, in 1756, an Englishman in the firing of porcelain in the kaolin add the use of animal bones ground into bone meal, surprisingly burned like fat like jade porcelain. Jade porcelain. Because of the bone powder this ingredient can increase the hardness and translucency of porcelain, and the strength is higher than the general porcelain, so it can be done than the general porcelain is thinner, more translucent, more white. This gave birth to a new type of bone china.

The emergence of bone china to make the British ceramic grade has taken a qualitative leap to meet the British consumers hope that not only high strength and elegant and beautiful porcelain requirements, so bone china was produced by a great deal of attention, bone china production process formula was imitated by industry insiders The recipe for the production process of bone china was copied by the industry and spread. The Longton region of England became the first production site for bone china. A number of workshops sprang up to try their hand at producing bone china.

John Doulton was one of the most famous representatives of bone china production. About 190 years ago, he set up his own workshop, which produced only rough earthenware. After his death, his son Henry followed in his father's footsteps and showed great skill in product reform and In 1877, because of his outstanding skills in the porcelain industry and the production of quality products, known as the "great potter" Henry was the King of England, "Sir" title, in recognition of his merits in the British porcelain industry. In 1901 In 1901, he was awarded by King Edward VII, was awarded the "Royal" trademark, become the world's consensus on the quality of bone china brand. 1966, rich in innovative spirit of Henry, once again won the "Queen's innovative industrial technology" award. So that it embarked on a porcelain career ROYAL DOULTON has gradually become the largest British bone china export manufacturer.

2. Characteristics of bone china

Bone china material is exquisite, fine production, strict standards, its regularity, whiteness, transparency, thermal stability and other indicators are extremely high requirements. Due to the complexity of high-grade bone china process, production is more difficult than ordinary daily-use porcelain, its production technology is difficult to popularize.

Bone china because of its unique shape, simple and bright, white and delicate texture, for a long time has been the aristocracy of countries with porcelain.

Bone china produced in the United Kingdom a high-grade porcelain, has a history of more than 260 years. Because of its "thin as paper, translucent as a mirror, sound as a chime, white as jade", the porcelain is delicate and transparent, beautiful and elegant, color surface glossy, colorful flower surface characteristics, achievements of its white texture and noble shape, both the use of the dual-value and art, the history of the palace specialties and the collection of treasures of the aristocracy. Bone china after generations of master craftsmen's hands, gradually become the world's ceramic treasures.

Bone china is the British royal special porcelain is also the Zhongnanhai designated porcelain mug, it is recognized as the world's high-grade porcelain. Bone china tableware not only has a beautiful appearance, but also has the quality of maintaining people's health. Bone china is in the traditional ceramic raw materials added to the animal bone powder after firing and become, tire thin and bright, with greater toughness. Bone china is a green ceramic spokesman, glazed bone china is fused to the picture in a high-temperature transparent glaze, and the picture is not easy to wear and tear, do not fall off, can be deservedly called "health ceramics".

Bone china material is exquisite, fine production, strict standards, its regularity, whiteness, transparency, thermal stability and other physical and chemical indicators are extremely high requirements. Bone china various Chinese and Western tableware with its high quality, high style, high grade to become a major star hotel upgrade must choose porcelain. Bone china tea set, coffee set family set has become the ideal appliances for all sizes of companies and wealthy families, but also the best gift for friends and relatives.

3.Bone china production process

1). Raw material

Excellent bone china is made by adding a large amount of cow's bone meal containing fewer impurities to the raw materials of feldspar, gueldspar, and clay as the main raw materials, and the molding is made by adding a large amount of cow's bone meal containing fewer impurities to the raw materials: because the raw materials contain a large amount of bone meal, it makes the clay less viscous, and so the molding needs to be made with extra care during the process of production.

2). Firing

(1). After the molding process to 1250 ℃ of the highest temperature calcination, calcination process due to bone china shrinkage is very large, so after kiln firing the finished product will shrink 20% (general porcelain shrinkage of 7%), so the shape of the deformation, plates, bowls, etc. must be placed on top of the special Converse bowl for a long time to burn training.

(2). After that, shape bending and size checking, grinding the surface with a sprayer sprayed with glaze, into the kiln for 1150 ℃ glaze firing.

3). Coloring

The general coloring method is to put transfer paper on the white texture of the finished product and fire it at 820℃.

Inspection Strict inspections are carried out at each stage, and only qualified products are sent to the next stage to be made into finished products for shipment.

4.The main characteristics of bone china

1). Appearance of beauty: porcelain is delicate and transparent, beautiful and elegant, colorful surface moist and shiny, colorful flower surface.

2). High-grade: produced in Britain, has long been the British royal family and the aristocracy of the special porcelain, is a high-grade porcelain, both the use and the double value of art.

3). Craftsmanship: the second firing, complex technology, only the United Kingdom, China, Korea, Japan, Germany, Russia, Thailand have production.

4). Processing is difficult: in the firing process, the degree of regularity, whiteness, transparency, thermal stability and other physical and chemical indicators are extremely high requirements, resulting in a high rate of scrap.

5. Identification of bone china

1). Color: bone china contains powder because the porcelain itself presents a natural milky white, in layman's terms is with a bit of yellow, this feature is any other porcelain can not be imitated.

2). Transparency: bone china itself to make the recipe for the reason that there is an important external feature is permeability, but this feature is not exclusive to bone china, the market of shellfish porcelain, white porcelain, pearl porcelain as long as you do some of the thin, there is also permeability, but bone china and their The permeability of bone china is different, for customers, bone china in the light bulb to see, bone meal content of high-grade bone china is the whole permeable, bone meal content of bone china and other types of bone china and other porcelain in the effect of permeability is a clear difference. Moreover, the same thickness of porcelain, bone The permeability of bone china is much higher than similar porcelains.

3). Sound: the two high-grade bone china products gently collide, the sound emitted like the sound of wind chimes as pleasant, and there will be a few seconds of echo, while the other porcelain species is basically no. 6.

6. Bone china maintenance

1). Try to wash by hand. If you really do not want to wash by hand, you need to choose a "porcelain and crystal" type of washing function of the dishwasher.

2). Do not microwave dishes that contain gold (unless they contain microwavable gold).

3). Choose a detergent with a pH value between 11 and 11.5.

4). When washing with water, the water temperature should preferably not exceed 80°C.

5). Do not immerse the hot cup directly into cold water to avoid damage to the porcelain by rapid change of temperature.

6). If the product is slightly scratched, use toothpaste to polish it gently to minimize the scratches.

7). If there are tea stains, use lemon juice or vinegar to clean.

8). It is better not to use the product in sudden heat or cold, in order to avoid cracking.

9). Don't put it on the open fire directly (except for the stewing pot).

10). Bone china is delicate and needs careful maintenance.

11). Bone china's in the process of use do not excessive hot and cold alternation, such as in the bone china poured into boiling water, should first use warm boiling water to scald the mug, and then poured into the boiling water, in order to prevent bursting.

7. Selection of bone china

1). Look: the color is milky white, the glaze is uniform, the tire is thin and bright, refreshing.

2). Listen: the left hand palm straight, stretching flat, the bone china vessel in the palm, the right hand hit the edge of the vessel, the sound is crisp and clear, there is a residual sound.

3). Transparent: the cup over the light source, light transmission, soft color for the best.

8. Classification of bone china

1). New Bone China

New bone china is generally called New Bone, Canton Fair no one in the name behind the word China, which was originally an ordinary high-white porcelain, calcium oxide content in the composition is slightly higher than ordinary porcelain, there is a certain degree of translucency, bone china mug manufacturers have given up a The name of a dragon and phoenix, called the new bone china. The main difference between its and bone china (bone china) has the following points:

(1). The raw materials used are different, bone china added more than 40% of bone meal, the new bone china did not add bone meal;

(2). Bone china is fired twice, while new bone china is fired once;

(3). Bone china has a softer whiteness than new bone china, higher transparency, lighter porcelain, and far better appearance than new bone china;

(4). Listen to the sound: the bone china in the heart of the hand, take a pen or a small stick to knock down the bone china bowl will sound like a bell like a ringing sound;

In short, the new bone china is not a new variety of bone china, but to borrow the name only.

2). Low Bone China

Low bone china, is a newly developed porcelain, and bone china has a few blood relations. Generally speaking, raw materials containing 10% bone meal porcelain can be called low-bone china, and bone china generally contains about 40% bone meal; it has and bone china comparable transparency, thinness and finish, but the price of the porcelain. Degree of transparency, thinness and finish, while the price is much cheaper than bone china. Therefore, just one side of the market by the low-grade hotels welcome. It has the following characteristics:

(1). The color of low bone china is the natural milky white color unique to natural bone powder, beautiful and generous!

(2). Appearance: fine and transparent porcelain, beautiful and elegant, colorful surface as jade, colorful flower surface.

(3). High strength, fine and hard products are not easy to wear and rupture, 180 ℃ and 20 ℃ heat exchange in water once without cracking, water absorption rate of less than 0.003%, suitable for dishwashers.

(4). With translucency, lightweight, mainly for mid-range hotel forecourt table, high-grade hotel table and kitchen use.

Although low bone china has most of the characteristics of bone china and popular, but there are differences between the two:

(1). The difference in the content of bone meal: generally contains 10% of bone meal can be called low bone china, while bone china needs to contain more than 30%.

(2). High bone china is required to be fired twice, while low bone china only needs to be fired once.

(3). High bone china is glazed after the product is plain fired and then glazed through a spray gun, while low bone china is glazed by simply dipping the entire clay blank into the glaze and then removing it to dry.

Note that, in general, most of the bone china produced in Tangshan is high bone china, Jingdezhen produced mostly low bone china.

9. The difference between white porcelain and bone china

How to distinguish between white porcelain and bone china when buying? In fact, the method is very simple. Summarized is the following four points: estimate the weight, look at the shape, identify the color, listen to the sound.

1). Estimated weight: weight above the white porcelain, bone china, the two comparisons, the same weight of the porcelain shape is generally said to be slightly heavier white porcelain, bone china lighter.

2). Observation shape: shape to distinguish, because of the process and raw materials, bone china relative to white porcelain is thinner, more rounded and smooth shape, better light transmission.

3). Identify the color: high-grade bone china porcelain fine and dense, smooth surface, glaze bright, color is a natural milky white, the higher the content of bone meal is more close to milky white, on the contrary, if the bone meal content is low, bone china itself is very obvious yellow.

4). Listen to the sound: from the tone, white porcelain is heavier and thicker, the two bowls touched by the "ding" sound, there is basically no echo; and will be two high-grade bone china bowls placed on the hands of the spread for the collision, note that bone china is a high-temperature firing of porcelain, hardness is very high, such a collision will not appear broken.

10. China's bone china status

China first began in 1976 by the first porcelain mug factory in Tangshan City and the Tangshan Ceramic Research Institute. With the improvement of people's living standards, bone china as the world's recognized high-grade porcelain, more and more sought after by people, and its market scale is gradually expanding. China's all over the strife All over China, a variety of bone china, the main places of origin: Hebei, Shandong, Guangdong, Jiangxi and other provinces, and the scale of the trend is expanding day by day.

Black smoke on ceramic mugs, does it affect use?

Xinxiang Custom Ceramic Mug Manufacturer, When we are shopping for ceramic mugs, occasionally we will see ceramic mugs inside or outside will have part of the mug body showing black gray, feel as if it was burned by the fire left behind the smoldering color. Do you know that such a coffee mug can be used normally? What is the cause of this?

Ceramic coffee mug partially or completely black and gray phenomenon is called smoky. This defect is because the billet oxidation is incomplete or reduction too early, so that the billet in the body of carbonaceous organic matter and low-temperature carbon deposits can not be burned out of time, the glaze layer is closed.

By the glaze layer is closed, the surface of the ceramic mug is black and gray, with the shape of smoke. According to Xinxiang ceramic manufacturer more than 20 years of experience in the production of coffee mugs know that the factors affecting the smoke are.

1. In the oxidation stage of burning small and medium fire insulation, oxidation is incomplete, part of the carbon residue in the body of the billet, so that the billet section was gray-black, especially when the billet contains a large amount of carbon in the use of clay, such as gangue, etc., it should be more in the glaze layer before the melting of the billet in the body of the full oxidation of the carbon. For the billet does not contain carbon products should also be in the fire insulation stage to strengthen the oxidation of coal-fired batch kiln and thick tire products, should pay special attention. This is because the batch kiln, ignition kiln temperature is low, more water vapor, plus this time the flue gas temperature is low, the chimney pumping force is weak, in the coal and pry furnace in a short period of time, the nature of the flame in the kiln is a reducing gas, at this time not only the carbon inside the body of the carbon can not be excluded, but also make the body of the billet deposition of carbon, especially when the kiln billet moisture content is high, it is easier to make the products produce water black. Therefore, the fire insulation stage (generally between 1000 ~ 1100 ℃), to maintain a strong oxidizing gas, and there is enough insulation time. That is to say, in the kiln operation, should control the grate on the ash layer, fire layer, the thickness of the coal layer, to ensure good ventilation, excess air coefficient is large, the fire layer of the combustion room clear Bright, each time you add the coal should be burned through, in order to make the billet get fully oxidized. Otherwise, the amount of coal added at this time is too much, the ash layer is too thick, poor ventilation under the stove bar, combustion does not penetrate, the combustion chamber produced by the free carbonaceous flue gas, long time to store in the kiln, and this stage, the billet stomata Rate and the largest billet, strong adsorption, it is easy to adsorb the smoke, resulting in carbon deposition, that is, we see the black and gray smoke pattern on the mug.

2. Reduction stage later, the reduction gas is too thick, that is, when the glaze has been melted, the kiln still maintains a strong reduction gas, but not in time to turn into a weak reduction gas or neutral gas, the product is still in the reduction gas, then the CO in the flue gas decomposition occurs at high temperatures resulting in the area of the material carbon, especially when using calcium glaze, it is easy to adsorb the smoke, thus causing carbon deposition, which is the black and gray smoke pattern we see on the cups. Calcium glaze, because CaO carbon absorption phenomenon is more serious, the most likely to form glaze smoky.

3. Ceramic mug black also need to analyze the billet glaze formula is reasonable. Such as the use of excessive CaO or other flux, so that the billet glaze prematurely produce liquid phase and melt, glass range is too narrow, so that the deposition of carbon can not be burned out in time, or too large a temperature difference between the kiln to ensure that the product gas changes, so that part of the product is in a chaotic gas. So that part of the product is in the chaos of the gas or fuel containing too much sulfur, its sulfur gas in the kiln to stay too long, then the sulfur will take the oxygen in the flue gas, so that the reduction gas becomes thick, easy to produce smoky defects.

In summary, China ceramic mug factoies think these are the 3 reasons for ceramic mug smoking. This can be drawn in the production stage, how to avoid producing smoked ceramic mug. Then, such a ceramic cup whether it affects the use, can buy it? Theoretical conditions, the smoke is produced inside the mug, the cup Outside the glaze to cover it inside, is not to affect the use. However, its aesthetics are not consistent with other ceramic mugs.

The process of making customized bone china dinnerware

Xinxiang ceramic mug manufacturer, The formation of bone china relies mainly on silicon oxide, aluminum oxide and calcium oxide, of which the higher the calcium oxide content, the better the color. In nature, there are not many sources of calcium oxide, so animal bone meal is chosen as the source of calcium oxide.

In fact, the so-called bone china is a bone china product made from the ashes of herbivorous animals (mainly Ca3(PO4)2) as raw material, mixed with high-quality kaolin, quartz and other auxiliary materials, and glazed and fired at 1280℃. Generally speaking, the raw material to add 25% of the bone powder can be called bone china, but today the world recognized the texture of the best bone china for 45% -51% of the content of bone powder, and to the cattle bone is good.

Its production process through to the grouting, mold pressing embryo, gypsum mold dehydration, as well as the initial firing, glaze firing, paste flower paper baking and other processes, the high temperature firing, become high whiteness, high transparency, fine custom porcelain mug. Bone china in the firing process, the degree of regularity, whiteness, transparency, thermal stability and other physical and chemical indicators are extremely high requirements, resulting in a high rate of scrap. Because of the material is exquisite, fine production, strict standards, so the value is higher than other kinds of porcelain.

Unique firing process and the addition of bone carbon, so that the impurities in the porcelain clay is eliminated, bone china appears more white, delicate, translucent, lightweight, very few defects, and thinner than the general porcelain, a special sense of cleanliness in the visual sense of the strength of higher than the general porcelain, is twice as much as the daily use of porcelain. The higher the content of bone meal, the clay content is relatively lower, in the production process, the easier it is to burn crack, in the molding requires higher technology, increasing the difficulty of firing, so it is more precious.

Some people have done this experiment, put 4 bone china cup pad in a Rolls-Royce under the wheels, these 4 crystalline cups can actually be competent to support the weight of the caravan!

High-grade porcelain and bone china similar to the shell porcelain and pearl porcelain, because the cost is too high almost no industrial production, so bone china is recognized as the world's most high-grade porcelain.

The Royal Family's Favorite Things

British royalty, the U.S. middle and upper class people drink tea, mostly with bone china mugs, more than two hundred years favored by the British royal family, Queen Elizabeth, Prince Charles, Princess Diana are its honored guests.

The moment you meet bone china, her bones contained in the aristocratic temperament inadvertently exposed to the elegance. Bone china from the 18th century from the Age of Enlightenment, the royal family in Europe shine, become a nobleman table on the delicate bone. Bone china has been used by the British royal family for nearly 250 years, Russia's Queen Katherine is also a loyal supporter of bone china, had 952 pieces of bone china, from the 1902 Roosevelt Presidential White House Banquet, to 1935, the Queen Mary's first voyage on the luxury liner, to the Queen Elizabeth's coronation in 1953, the feast in the annals of history, bone china tableware is always in the list of the exquisite stature of the proud. In the European focus on the quality of life of ordinary people, it is easy to see the elegant hostess, with bone china brewing tea. The gentle golden border, just like outlining the details of a perfect life. There are many bone china pieces that have been honored by the royal family and made famous. When the hands of the bone china cup, see the light through the soft milky white, may wish to live a meticulous, into the hands of the special, the achievement of a story that has been passed down for hundreds of years.

Production process of customized branded ceramic coffee mugs

Xinxiang custom ceramic mug manufacturer, 1. Billet mud

Blending the ingredients into a puree. For specific ingredients see: Various raw materials for ceramic coffee mugs

2. Blank mold making

The factory uses a lathe press. After installing a new mold into the press, the mold is first adjusted (note: the new mold needs to wait for drying before it can be used), then the cut blanks are put into the mold, and the head of the press is dropped into the mold and rotated, and the blank production is completed. The mug handle is usually made by grouting (it takes about 10-15 minutes to solidify and mold).

3. Assembly

The pressed blanks are left for 5-10 minutes to harden. Remove the handle from the mug after it has solidified. First, flatten the ends of the handle, then correct the excess clay on the handle. Finally, holding the handle in your hand, dip the handle into the clay and glue the handle and body together to form a complete ceramic coffee mug. It takes about 20-30 minutes to dry the finished mug (increase the blowing force and temperature to speed up the drying process).

4. Repair

After drying ceramic mug blanks need to trim and wash. The purpose is to remove the protruding particles on the surface of the mug, and the bottom of the mug will be polished smooth. After trimming and washing the mug blanks, the final drying. This takes about 10 hours until all the water in the mugs has evaporated.

5. Glaze

Glaze the completely dried mugs. There are many types of glazes (Ingredients and Classification of Glazes: The characteristics and functions of 7 glazes of ceramic mugs). In the glazing session, the simplest is a single-color glaze, in which the entire molded cup is placed in the glaze. If the mug requires multiple glaze colors, the operation is a bit more complicated. An example is the common two-tone glazed mug - one color on the outside and another color on the inside. The glazing process for a two-color glazed mug is as follows:

1). Glaze the mouth of the mug. The mouth of the mug is where the two colors connect, so it requires special treatment. The mouth of the mug should be dipped in the corresponding glaze, and to prevent the two glazes from overlapping, the glaze that dips the mouth of the mug should be filled with a water-resistant agent.

2). Glaze the inside. Place the branded ceramic mug with the mouth down into the machine. With the movement of the conveyor belt, the glaze nozzle will invert the inside wall of the mug, evenly sprayed with glaze color.

3). Glaze the outer wall. After drying the mug, put it into the glaze liquid, the industry is called dip glaze.

6. Enter the kiln

The glazed mugs will be dried, you can enter the kiln firing. Time is more than 10 hours, according to the mug type different time is also different. In addition, according to the customer's requirements for the color of the mug, there are high temperature firing, medium temperature firing and low temperature firing.

7. Out of kiln

Out of the kiln The finished ceramic mugs are cooled in the kiln.

8. Decorate the paper

According to the customer's requirements, the picture will be made into flower paper. At present, there are many kinds of flower paper, more detailed see: Decal paper categories and decal techniques for ceramic coffee mugs At present, the most commonly used is the small film flower paper. Small film flower paper is composed of the bottom layer of base paper (also known as paper base), the middle layer of the sol, and the surface of the cover oil. Small film paper in accordance with the different barbecue temperature can be divided into: high-temperature flower paper and low-temperature flower paper.

1). The main component of low-temperature flower paper is ink material, the production of color material is slow to dry, need enough time to fully dry completely before the second process; low-temperature flower paper firing temperature: baked 120-180 degrees. Low-temperature flower paper paper affordable, colorful, versatile, glossy, three-dimensional sense of strong, anti-corrosion environmental protection, but the adhesion is relatively weak.

2). High-temperature paper: glazed, glazed, under the glaze, glazed paper firing temperature of 780 degrees or so, glazed paper, firing temperature 1250 degrees to 1380 degrees; high-temperature paper wear resistance is good, long time to place there will be no peeling off the phenomenon of color loss, strong adhesion, but its price is higher than the low-temperature paper, easy to burst flowers and other phenomena, the temperature of the difficulty of controlling a single.

Sometimes according to different colors to choose a different temperature. Especially with gold flower paper, the temperature is too high easy to burn black, discoloration; too low if the color is not bright enough, dark. After the paper is attached to the cup, it is fired in the kiln. According to the different paper, set the firing temperature.

Lastly, there is the tearing process. There are two kinds of film tearing: cold tearing and hot tearing (cold tearing is to tear the film before baking the flowers, and the other is to tear the film after baking for hot tearing), cold tearing every time you stick, the time for 10-24 hours is the best time. Try to put in a cool and ventilated place, easy to tear the film. Winter weather is colder, generally use hot tear.

In summary, customized personalized ceramic coffee mugs, from the ore to the finished product of the whole process of change. Of course, the production process of each factory is not very different, but the quality of the product, the grade of raw materials and the level of craftsmanship is still different. If you want to customize branded ceramic coffee mugs, it is recommended to choose a professional ceramic production factory.

Ceramic flower paper classification and characteristics of appreciation

Xinxiang custom ceramic mug manufacturer, Ceramic applique, is to paste the color pattern on the stained paper to ceramic blanks or glaze, also known as "flower shift", is the most widely used in modern ceramics, a decorative technique. Pattern decoration to rely on printing reproduction method to achieve, that is, directly on the object printing patterns. For shaped and special requirements of the bearing material and bearer, it is necessary to use indirect decorative method. Small film paper is to meet this requirement of a decorative method.

Small film stained paper, also known as water transfer decal paper, it is the first pattern printed on a pre-coated water-soluble adhesive special paper, and then through the water soak wetting, transfer attached to the surface of the object of a decorative process. Small membrane flower paper is composed of the bottom layer of base paper (also known as paper base), the middle layer of the soluble glue, and the surface of the cover oil.

Membrane paper according to the different barbecue temperature after the transfer of paste can be divided into: high-temperature flower paper and low-temperature flower paper. Here we look at their differences and commonalities:

1. low-temperature stained paper is the main component of the ink material, the production of color material drying slow, need enough time to fully dry completely to the second process; low-temperature flower paper firing temperature: baked 120-180 degrees. Low-temperature floral paper paper affordable, colorful, versatile, glossy, three-dimensional sense of strong, anti-corrosion environmental protection, but the adhesion is relatively weak.

2. High-temperature paper points: glazed, glazed, under the glaze, glazed paper is mainly used for bottles and daily-use porcelain, firing temperature of 780 degrees or so, glazed, under the glaze is mainly used for daily-use porcelain, art porcelain, etc., some high-grade bottles are also used in glazed paper, firing temperature of 1250 degrees to 1380 degrees; high-temperature flower paper wear resistance is good, often placed in a period of time will not be peeling off the phenomenon of loss of color, adhesion is stronger, but the price is higher than the Low-temperature paper is high, easy to burst flowers and other phenomena, the difficulty of controlling the temperature single, sometimes according to different colors to choose a different temperature. Especially with gold stained paper, the temperature is too high easy to burn black, discoloration; too low if the color is not bright enough, dark.

3. The life of the flower paper: low-temperature flower paper service life time than high-temperature flower paper short, the best decal time is within a month to be used up, too long, then easy to oxidize, so basically do not do inventory.

4. Decal paper dehydration: Decal bad dehydration phenomenon, generally the base paper problem, this time can not be too hard to pull, will pull the pattern of the paper bad, it is recommended to soak a little longer, but the water temperature can not be higher than 25 degrees, should be in 20-25 degrees is appropriate.

5. Decal: decal process, scrape the stained paper as much as possible with soft rubber, especially paste low-temperature flower surface, easy to scratch the pattern. In the decal need moisture fully dry, and then wipe again with a dry cloth.

6. tear film: divided into two kinds of cold tear and hot tear (cold tear is in the baking flower before tearing the film, another is baked and then tear the film for the hot tear), cold tear each time to paste, the time for 10-24 hours for the best time. Try to put in a cool and ventilated place, easy to tear the film. In winter, the weather is cold, generally use hot tearing.

7. Decal adhesion problems: in different ceramic mugs, will affect the efficacy of the paper, for example: the surface of the bottle will have a rough surface often a few problems, paste up to put half an hour on the phenomenon of shedding, mainly the plane is not smooth enough, we will usually be a special treatment of small patterns or the overall base film to do a big, increase the consolidation of the strength of each pattern; if the paste up to baking flowers or bad adhesion, can only be put to baking the temperature of flowers Increase the baking temperature or keep warm in the kiln for a longer time (if you still can't deal with the above problems, you can only brush a layer of wax on the position of the decal, and then paste the pattern to be pasted on it, adding a program. (This is only for the rough treatment of wine bottles, not with rough bottles, flower paper ink paste up will not have this problem)

8. Storage of stained paper: storage and transportation process can not be heavy pressure, should be placed in an upright position. It is recommended that the porcelain factory store the paper in a humidity of 60-75 degrees for storage.

2. Preheat the coffee mug: Heat up the ceramic coffee mug in order to seal in all the flavors of the coffee. The easiest way is to pour hot water into the ceramic coffee mug manufacturers or preheat the mug in the microwave.

Introducing New Stainless Steel Insulated Travel Mug and Tumbler Coffee Mugs

Xin xiang custom ceramic mug manufacturer, With some people relying on caffeine to get the extra energy they need during a busy day, and others simply enjoying the flavor and ritual of coffee, coffee plays a vital role in many people's lives. Whether you prefer espresso, Americano, latte, cappuccino, mocha, plain white, or any other type, the right mug will add to your coffee drinking experience. Finding the perfect mug that maintains the right temperature and is easy to clean is not always a straightforward process.

Personal preference will take into account factors like choosing between a thick or thin mug that you can wrap your hands around for warmth on cold mornings, or a smaller mug that will qualify you for another drink at lunchtime. Traveling needs and sizes will also help you decide which is the best coffee mug for you. Below you'll find the differences between the different types of mugs as well as our recommendations for the best mugs we found on the market.

Different Types of Coffee Mugs

Finding the perfect coffee mug online can be difficult because there are so many types and styles to choose from that it's hard to tell which one is best for you without holding it in your hands. To make your decision easier, this guide outlines some of the most popular types of logo ceramic coffee mugs.

Classic Mugs

Classic mugs, as the name suggests, are what most people imagine when they say "coffee mug". Traditional, but not boring, these mugs are found in most cupboards. This classic mug is usually made of ceramic, has a sturdy round handle, comes in a variety of sizes, can have different prints, slogans, sayings or images, or can be finished with a simple solid glaze. Classic mugs are usually microwaveable and very durable. Ceramic coffee mugs can be heavy and easily stained if they are light in color. Classic mugs can have relatively thin walls (although not as thin as Chinese teacups) or can be very thick, such as regular restaurant and diner mugs.

Traveling Mugs

Travel ceramic coffee mugs are the best option for those who like to drink their coffee on the go. Lightweight and portable travel mugs are usually made of stainless steel, although some ceramic models are also available. They feature a tight, leak-proof lid, usually made of insulated walls that reliably keep coffee hot for hours. Travel mugs are designed to fit in a car cup holder, so are able to drink coffee on the go, and some are completely leak-proof and can be easily placed in a bag or briefcase. The top of the mug can be heavy if the taper is too large, so balance is an important consideration, as is the design of the lid: spill-proof lids are great, but these lids with gaskets can easily get moldy if the lid is difficult to clean well.

Currently, the popular insulated travel mugs effectively solve the above problems. It has thermal insulation, a leak-proof lid, and the lower part of the cup is thin enough to fit directly into the car's cup holder. It allows us to drink hot coffee or iced coffee, to be realized. Report by China ceramic mug factories.

Non-Tipping Mugs

The Non-Tipping Mug is a new combination of classic and travel mugs. Changing the design of both, the mug features the insulation and lid of a travel mug, with a shorter, wider shape closer to a traditional mug, but usually without a handle. Not ideal for sipping in the car, the mugs are usually too wide to fit in the car's cup holder. However, they excel at keeping your coffee hot for long periods of time and taking it with you at work, and their designs are usually modern and sleek.

Currently, engineers have improved some of the shortcomings of the non-reclining cups. It makes the non-tipping mugs and insulated mugs blend together perfectly.

No matter what kind of mug, "as long as it exists, it has meaning". There are all people who like it. However, a perfect design also needs a good quality production factory to guarantee the quality. Whether it is a ceramic coffee mug, stainless steel insulated travel mug or a non-tipping cup, the quality and health of the cup will always be the basis of his favorite.

The characteristics and functions of 7 glazes of ceramic mugs

Xin xiang custom ceramic mug manufacturer co., ltd. The glaze of ceramic products (ceramic mugs) can be divided into transparent glaze, opacity glaze, color glaze, glossy glaze, matte glaze, cracked glaze (open piece), crystallized glaze according to the appearance characteristics.

1. Transparent glaze

Transparent glaze is also called clear glaze, which is mainly made of natural raw materials such as feldspar, quartz, limestone and kaolin. The clear glaze does not have the function of covering the bottom, and the color of the body itself can be reflected through the glaze layer. This kind of glaze is characterized by low cost, simple process, easy manufacture, wide firing range and stable performance. Apply on the surface of the object, and form a smooth film after drying, showing the original texture of the object surface.

The role of green glaze

Clear glaze is a colorless or colored glassy thin layer covering the surface of ceramic products. It is made of mineral raw materials (feldspar, quartz, talc, kaolin, etc.) and raw materials in a certain proportion (some raw materials can be made into frits first) After being ground to make a glaze slurry, it is applied on the surface of the green body and calcined at a certain temperature.Xinxiang ceramic factory thinks It can increase the mechanical strength, thermal stability and dielectric strength of the product, and it also has the characteristics of beautifying utensils, being easy to wipe and cleaning, and not being corroded by dust and filth.

2. Opacity glaze

Opacity glaze: also known as "covered glaze". An opaque, glass-like coating on a ceramic body that conceals the color and defects of the body. It is formed by adding an opacifying agent to ordinary transparent glaze. In addition, opacification can also be formed when there are a large number of fine air bubbles in the glaze layer. The opacity of traditional blue glaze is mainly due to this gas-phase opacification.

The role of opacity glaze

The reason for the opacification effect is caused by light scattering. The greater the difference in refractive index between the two, the higher the degree of opacification. Commonly used opacifiers are zircon, tin dioxide, titanium dioxide, ceria, zirconia, etc. Among them, zircon is rich in resources and low in cost. The opacification can also be separated by the glass phase of the glaze layer, that is, one is the basic glass, and the other is the dispersed glass phase particles. The chemical composition and refractive index of the two are different, and light scattering can also cause opacification. , known as "opalescence". When the glaze layer contains a large number of fine air bubbles, opacity can also be formed. The opacity of celadon glaze in ancient porcelain is mainly due to this gas phase opacification.

3. Color glaze

Color glaze: Add some kind of oxidized metal to the glaze, and after firing, it will show a certain inherent color, so it is called "color glaze". Different metal oxides are added to the glaze as coloring agents, and when fired at a certain temperature and temperature, glazes of different colors will appear and become colored glazes. Traditional color glazes include: blue glaze with iron as colorant; red glaze with copper as colorant; blue glaze with cobalt as colorant. In history, there are outstanding masterpieces of color glazes in many eras, such as green glaze and Junhong in Song Dynasty, Jihong in Ming Dynasty, Langyaohong, Wujin glaze and tea powder glaze in Qing Dynasty. The difference between color glaze and ordinary color glaze lies in the special firing process and formula of color glaze. The glaze surface of the color glaze must be calcined at a high temperature of over 1250 degrees Celsius to show its unique charm of radiant oil, rainbow color, and flowing clouds and waterfalls. Colored glaze Ceramic coffee mugs are the most common.

Classification of color glaze

There are three ways to classify color glazes: one is to classify them according to firing temperature, which can be divided into high temperature color glazes (about 1300 degrees), medium temperature color glazes (about 1200 degrees) and low temperature color glazes (about 1000 degrees). If 1250 degrees is used as the boundary, it can be divided into two types: high and low; second, it can be divided into two types: oxidized flame color glaze and reduced flame color glaze according to the flame properties after firing; third, it can be classified according to the appearance characteristics after firing. It is monochrome glaze, multi-color glaze (flower glaze), crackle glaze, matte glaze, crystalline glaze and so on. There are many kinds of high-temperature colors, nearly a hundred of them with names, which can be divided into the following systems: the red glaze system includes sacrificial red, Jun red, Langyao red, glaze red, beauty drunk, etc., mainly based on copper. Colorant. The green glaze system includes Tianqing, Longquan, Douqing, Yingqing, etc., mainly using iron as the colorant. The blue glaze system includes ji blue, enamel blue, ji blue, etc., mainly using cobalt as the colorant.

4. Glossy glaze

Glossy glaze: also known as ordinary glaze. Just the opposite of matte glaze, it is our most common glaze. This glaze goes through the glazing process and firing. Attached to the surface of the embryo body, forming a protective film. Its appearance reflects light strongly and is brighter. Ceramic products can increase the mechanical strength, thermal stability and dielectric strength of the products, and also have the characteristics of beautifying utensils, being easy to wipe and cleaning, and not being corroded by dust and filth.

5. Matte glaze

Matte glaze: also known as "bright glaze". It is a kind of glaze specially made for some occasions to prevent floating light stimulation without glass light on the surface. Can be made into a variety of colors, or imitate copper, iron, wood and so on. The production methods include reducing the firing temperature to make it incompletely melted, forming orange peel, wrinkles or silky patterns on the surface; increasing the emulsifier to reduce the silicon content; artificially treating with hydrofluoric acid, etc.

Matte glaze is a kind of microcrystalline glaze, and the precipitated crystals in the glaze are generally invisible to the naked eye. Matte glaze is not absolutely without light, but compared with ordinary glaze, the finish is poorer. Generally speaking, matte glazes do not have the ordinary glass-like luster, but still have a luster similar to silk threads. Instantaneous crystallization of this glaze occurs during melting or during slow cooling. The same glaze that becomes a matte glaze when cooled slowly becomes a glossy glaze when cooled rapidly. A good matte glaze should have a smooth finish that is pleasant to the touch and easy to clean.

6. Open slice (ice crack)

Ice crack", also known as open piece, also known as broken pattern porcelain, is a variety of ancient Longquan celadon. As a special decoration of porcelain, Ge kiln products in Song Dynasty are the most famous. Among the various glaze cracks of Ge Kiln, "ice crack" ranks first, known as "Ge Kiln's character, the pattern is based on ice crack". Because of its unique cracking during the firing process, it shows infinite natural beauty. It is a pity that the craft of firing "ice cracks" was lost after the Song Dynasty. Because it is lost, and because there are very few real objects. Therefore, restoring celadon ice cracks has become a thousand-year mystery. Ice cracked ceramic coffee mugs are similar to this.

Main features of ice cracks

A natural cracking phenomenon in the glaze of porcelain. There are two reasons for cracking: one is that the mud mud extends along a certain direction during molding, which affects the arrangement of molecules. The second is that the expansion coefficients of the blank and the glaze are different, and the shrinkage rate of the glaze layer is large when it is cooled after firing. It was originally a shortcoming in the firing of porcelain, but people intentionally use the law of cracking to make split glazes. There are two types of split glazes: one is the filling type, which fills the cracks of the fired glaze with soot, etc. The lines are black; the cracks can also be filled with coloring agents such as copper sulfate, showing brown-green lines. The other is the covering type, in which a layer of color glaze is covered on the fired bottom glaze, and then fired again to show cracks and reveal the color of the bottom glaze. According to the density of cracks and different patterns, the cracks are called ice cracks, roe lines, rubbish pieces, crab claw lines, cow hair lines and eel blood lines, etc. Counting nine winters, freezing three feet, hitting it with a mallet or a stone, the ice surface will slam, and there will be many white lines that explode, which are called ice cracks.

7. Crystal glaze

During the firing process of the product, because the glaze contains a sufficient amount of crystalline substances (melt), it is in a saturated state after melting, and crystallization is formed during the slow cooling process. It is a highly decorative artistic glaze, which originated from the color glaze in ancient my country. The fundamental feature that distinguishes crystalline glaze from ordinary glaze is that the glaze contains a certain amount of visible crystals (that is, the crystal flowers on or in the glaze that we can see).

Classification of crystal glaze

There are many types of crystal glazes, and there are many classification methods.

According to the crystal shape, it can be divided into crystals such as Tianmu, raindrop, tea powder, rust flower, chrysanthemum, radial, strip, spray, star, pine needle, spiral, star, granular, water chestnut, feather, etc. glaze.

According to product classification, it can be divided into display ceramic crystal glaze, architectural ceramic crystal glaze and daily ceramic crystal glaze.

According to the glaze processing method, it can be divided into raw material crystal glaze and frit crystal glaze. China ceramic mug suppliers

According to the firing temperature, it can be divided into high temperature, medium and low temperature crystalline glaze.

According to the crystal size, it can be divided into two categories: coarse crystal glaze and micro crystal glaze.

History of colored glaze mugs

The history of colored glaze mugs can be traced back to ancient times, and it first appeared in the Han Dynasty in China. At that time, colored glaze cups had been widely used in daily life, including food, entertainment and so on. The craftsmen at that time created rich and colorful colored glaze effects by mixing and using various glazes, such as blue and white, meat red, tea gray and so on.

With the passage of time, the production process of colored glaze mugs has gradually improved, and new glazes and techniques have also emerged. During the Song Dynasty, colored glaze mugs such as Yue Kiln celadon and Ding Kiln white porcelain were widely used and praised. During the Ming and Qing Dynasties, Jingdezhen became an important producing area of Chinese ceramics factories, and many distinctive colored glaze mugs appeared, such as multicolored mugs, pastel mugs, and red glazed mugs. Now, Shandong Zibo, Liling, Jingdezhen, Chaozhou and Tangshan have become the main producing areas of colored glaze mugs.

The main difference between colored glaze mugs and other mugs is the glaze. Next, China Ceramics Factory will introduce the glaze of the colored glaze mug.

Glaze

Glaze is a colorless or colored glassy thin layer covering the surface of ceramic products. It is made of mineral raw materials (feldspar, quartz, talc, kaolin, etc.) and raw materials in a certain proportion (some raw materials can be made into frit first) Grinding to make a glaze slurry, applying it on the surface of the green body, and calcining at a certain temperature. It can increase the mechanical strength, thermal stability and dielectric strength of the product, and it also has the characteristics of beautifying utensils, being easy to wipe and cleaning, and not being corroded by dust and filth.

Types of glaze

There are many types of glazes, which can be divided into enamel glaze, pottery glaze and flint glaze according to the body; according to the firing temperature, it can be divided into high temperature glaze and low temperature glaze; according to the appearance characteristics, it can be divided into transparent glaze, opacity glaze, color glaze, glossy Glaze, matte glaze, cracked glaze (open sheet), crystal glaze, etc.; according to the glaze composition, it can be divided into lime glaze, feldspar glaze, lead glaze, lead-free glaze, boron glaze, lead-boron glaze, etc.

1. Tang Sancai, popular in the Tang Dynasty, is a plain-fired carcass painted with white, green, brown, and yellow glazes, and baked at 1100 degrees. It was mostly used as funerary objects at that time;

2. On-glaze color, which is painted on the fired plain ware, and then baked at low temperature. Because the color is attached to the glaze, it is named. It was first seen in the Song Dynasty;

3. Underglaze color, painted on the green body, then glazed and fired at high temperature, the color pattern will never fall off under the glaze.

4. Underglaze red, painted on the tire with copper oxide as the colorant, and fired at high temperature after glazing to produce red flowers on a white background, which began in Jingdezhen in the Yuan Dynasty;

5. Doucai: Draw the outline of the pattern with blue and white on the green body. After glazing and firing ceramics, fill the outline with various colors, and then fire it for the second time in a low-temperature furnace. The picture shows blue and white underglaze and The colors on the glaze are more beautiful than each other, hence the name. It began in the Chenghua period of the Ming Dynasty;

6. Open pieces, both ice cracks and glaze cracks are of the same type as ice cracks. Due to the different expansion coefficients of tires and glazes, premature exit from the kiln is caused by cold air, which is the main feature of Ge Kiln in Song Dynasty;

7. Blue and white, one of the varieties of underglaze color, uses cobalt oxide as the color agent, paints on the blank body, covers with transparent glaze, and is fired at a high temperature of 1280--1320 degrees, blue and white, the main porcelain of Ming and Qing Dynasties;

8. In-glaze color: Decorate on glazed porcelain, and then fire at high temperature. The color material or glaze material is melted into the previous glaze, which seems to be in the middle, similar to the glaze color process, but it is also the same as the glaze. There is a difference in coloring.

Glazing process

Glazing technology is a kind of ancient ceramics manufacturing technology, which refers to applying glaze slurry on the surface of the formed ceramic body. There are mainly seven methods of dipping glaze, swaying glaze, pouring glaze, brushing glaze, sprinkling glaze, and rolling glaze.

Glaze Recipe: One's clothing must fit. When sewing clothes, what kind of cloth to choose and what style to use must have a comprehensive consideration. Glazing ceramic products requires careful research to adapt the glaze to the requirements of the ceramic body. This is the so-called glaze formula. There are many factors to consider when deciding on a glaze formula. The following three points should be grasped:

(1) Since the glaze cannot exist independently from the body, the physical and chemical properties of the body must be mastered first, that is, the chemical composition of the body. Expansion performance, boiling humidity and finished product performance requirements, etc. Among them, the appropriate matching of the expansion coefficients of the glaze and the body is the main condition for whether the glaze is well fixed on the surface of the body after firing. If the expansion coefficient of the glaze is smaller than that of the blank, the glaze layer will peel off during cooling; if the expansion coefficient of the glaze is greater than that of the blank, the glaze layer will crack during cooling, and even when the gap between the blank glazes is too large The product may also fail under stress.

(2) The requirements for the glaze itself must be clarified, such as whiteness, transparency, chemical stability and mechanical properties.

(3) Attention must be paid to the purity of glaze raw materials. Because the impurities contained in the raw materials, such as iron and cobalt compounds, will have a great impact on the whiteness and dielectric properties of the glaze.

In short, there is a general principle to be grasped in the study of glaze: generally change the composition of the glaze to adapt to the body rather than changing the composition of the body to adapt to the glaze. It is also like sewing clothes to fit the body instead of letting the body fit the clothes.

To sum up, the ceramic mug under the glaze cover is also the colored glaze mug. The color glaze mug has super stability and aesthetics. The glaze comes from ore, and no toxic substances are added in the glaze process. Therefore, the color glaze mug can be used whether it is a microwave oven or a dishwasher. The color glaze mug can also be customized with LOGO and packaging, which is a suitable gift for corporate gifts and brand gifts.
