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.

Decal paper categories and decal techniques for ceramic coffee mugs

Xin xiang custom ceramic mug manufacturer, Ceramic mugs come in beautiful prints, photos, or solid colors. Do you know how these images or colors are made? How does it integrate with the ceramic coffee mug? Are they harmful in the microwave? If you want to know this, you have to understand the decal classification and decal technology of ceramic coffee mugs.

Types of decals

Decal paper is a craft paper with patterns printed on the surface of the backing paper, which has a large market. According to the nature of the paper, it can be divided into three categories: butyral film paper, rough underglaze decal paper, and water transfer decal paper.

According to the nature of paper (backing paper), it can be divided into three categories:

1) Butyral film paper; 2) Underglaze decal paper; 3) Water transfer decal paper.

Butyral film flower paper

Butyral film decal paper is also called "alcohol decal paper". It uses butyral and alcohol as raw materials to make a film as a backing paper, and print patterns on the surface of the backing paper. This process still has a large market because of its low cost. , only 1/3 of the price of water-shifting decals, and the craftsmanship and effect can basically meet the decoration requirements. Its disadvantages lie in three aspects: first, the backing paper of the butyral film is thick, and the edge is not neat after use, and it is difficult to register the pattern when printing; on the other hand, due to the nature of the film, it cannot print precious metal preparations; On the one hand, its ductility is limited, and it cannot be moved and pasted on an irregular plane. However, because the large-film decal paper has the most competitive advantage of low price, it will continue to be used as a decorative material for Chinese ceramic factories.

Underglaze flower paper

Underglaze flower paper is developed from the most primitive lithographic (lead printing) flower paper. It uses simple water-absorbing, soft paper as the backing paper, screen-prints the water-based glazed reverse-printed pattern on the surface, and then pastes it on the embryonic glaze of the ceramic. The feature of this process is that it is easy to fire (one-time firing), saves cost, is bright, has good wear resistance, and meets international hygienic standards. It also occupies a certain place in the decoration of tableware porcelain. However, its disadvantages are that the pattern is thick, the decals are difficult, and the packaging is difficult.

Water transfer decals

Water transfer decal paper (commonly known as small film decal paper) is more popular in domestic ceramic decoration. The printing form of water transfer decal paper can be flat printing, screen printing and steel plate transfer printing, and the most commonly used of the three is screen printing.

The most basic material of water transfer decal paper is small film bottom paper, which is a kind of paper with strong water absorption and covered with water-soluble adhesive film on the surface. After the printed decal paper is soaked in water, after the paper absorbs water, Dissolving the water sol on the surface can make the pattern of the oil agent slide and separate from the paper surface. The separated pattern still has a little water sol, and it can be pasted on the porcelain. As the name suggests, it is called water transfer decal.

The backing paper of the water-shifting decal paper should have good water absorption, but it also brings contradictions, that is, during the printing process, if the backing paper absorbs too much water, it will become heavy and soft, and the paper will be difficult to organize and handle. Moreover, the paper is bound to swell, resulting in inaccurate color registration during the printing process. This inaccurate feature makes the expansion irregular, which is a difficult problem to solve. If it encounters dry weather, the paper will shrink and become smaller, which will also cause inaccurate color registration. When this happens, the four corners of the paper may be warped, which is not easy to organize and not easy to print. Therefore, when choosing the bottom paper, its stability should be emphasized. Secondly, the environment of the printing workshop should be kept at constant temperature and humidity, with the temperature controlled at 22°C and the humidity around 55%. Another key point of paper is the surface performance of hydrosol, which requires smoothness and is not easy to harden, shrink, and crack. To identify the quality of the paper and whether it is suitable for your production, it is necessary to test it by simulating production. The four corners or one side of the flower paper are warped, most of which are caused by the hardening and shrinkage of the hydrosol surface. If it is difficult to dehydrate and paste the printed flower paper, it is because the hydrosol surface on the surface of the paper cracks when the printed pattern is drying. After the cover glue is applied, the cover glue sticks to the paper due to cracks. The phenomenon can be observed with a X10 magnifying glass. The backing paper with this phenomenon is not suitable for drying, and can only be printed with few colors, and can only be dried naturally, and cannot be put into an oven.

Melamine flower paper (melamine tableware)

It is also called melamine flower paper or imitation porcelain flower paper. The material is 37g to 60g long-fiber paper. The finished product is printed by offset printing or silk screen. In the oven at 70-100 degrees

The linking agent in the ink is baked and volatilized. Then brush the melamine formaldehyde resin on the flower paper. The concentration of the resin is prepared according to the standard of 95 degrees water temperature to completely dissolve the resin. Then dry. Pass through the molding machine for 20-35 seconds and melamine tableware Complete fusion. Melamine tableware in fast food restaurants has been produced. A 37-gram melamine flower paper has been developed for melamine cups. Developed a 60g masking paper. Titanium dioxide was added when making pulp. It solved the problem of color penetration of ordinary melamine flower paper.

Melamine flower paper is divided into long-fiber paper and short-fiber paper in terms of material. The strength of short-fiber paper is slightly weaker. It is easier to break when dealing with flower paper. And the uneven distribution of fibers is easy to produce white stains.

Technical characteristics of flower paper color removal

The color removal of flower paper refers to the color separation of the original paper of flower paper, which is to decompose the original paper into single colors suitable for printing according to the needs of different printing methods.

Four colors are divided into four colors of magenta/cyan/yellow/black for overprinting.

Spot color is to distinguish the different hues of the original, and to distinguish the different saturation and lightness of the unified hue for overprinting. For example, divide a group of pictures of red flowers and green leaves into light green, medium green, dark green, light red, dark red, medium red and brown.

The commonly used software for color removal is: Photoshop, CorelDRAW

Ceramic decal craft

Ceramic decals, also known as "moving flowers", are the most widely used decorative techniques in modern ceramics.

Move flowers

Migrating flowers is to use the paste method to move the colored patterns on the flower paper to the ceramic body or glaze. Sub-glaze decals and under-glaze decals. On-glaze decals include film decals, clear water decals and glue decals. For underglaze decals, only the outline of the pattern is printed on the decal paper, and then manually filled in after pad printing; there are also lines and colors that are pasted at one time, which are called decals with water. There are two kinds of decals: paper and plastic film. Paper decals need to go through the processes of peeling and washing. Later, film decals were invented, which eliminates the need for decals and facilitates mechanized and continuous operations.

Screen printing ceramic decal paper use range and characteristics

1) Ceramic decal paper is mainly used for the decoration of patterns and colors of ceramic vessels, replacing the hand-painted and spray-painted techniques that have been used in the past.

2) The resolution of silk screen ceramic decal paper can reach 40-50 lines/cm.

3) After the screen printing ink pattern on the ceramic decal paper is pasted on the ceramic vessel, it needs to be fired at 700-800°C or 1100-1350°C to adhere firmly, and the color depends on the type of coloring agent in the ceramic.

4) Ceramic decal paper is the carrier of ceramic ink, which can be divided into ceramic overglaze decal paper and ceramic underglaze decal paper. The types of decal paper are different due to their composition.

5) Due to the strong hiding power and poor transparency of ceramic ink, it is not yet possible to use the principle of three primary colors for printing. The dot printing method adopts non-superimposed side-by-side special color ink dot printing.

6) The ink printed on overglaze decal paper is high-temperature solvent-based ink; the ink printed on underglaze decal paper is high-temperature water-based ink.

Ceramic coffee mug buying guide and How to use it correctly

Xin xiang custom ceramic mug manufacturer, When purchasing a coffee mug, you can choose a suitable ceramic coffee mug according to the type of coffee you choose and your personal habits. Coffee is divided into eight categories: 1. Espresso; 2. Latte; 3. Cappuccino; 4. Cortado; 5. Mocha; 6. Bombo; 7. Bicerin; 8.Macchiato, Then choose a coffee mug according to your personal preferences and drinking occasions. Generally speaking, a white coffee mug will make you feel the taste of coffee is stronger. A blue mug will make your coffee taste lighter. In addition, small coffee mugs below 100cc are generally used for Italian coffee, and mugs without mug holders are often used for coffee with a high proportion of milk, such as latte and milk coffee.

In terms of personal preference, in addition to the appearance of the custom ceramic coffee mug, you should also pick it up to see if it is smooth, so that you will feel convenient and comfortable when using it. For the weight of the mug, it is advisable to choose a light mug, because a lighter mug has a denser texture. The denser texture means that the raw material particles of the mug are fine, and the surface of the mug is tight and the pores are small, which is not easy to make coffee stains adhere to the surface of the mug.

A mug of fragrant and mellow coffee is a must-have item for white-collar workers in their daily work. For a good mug of coffee, every step from the selection of coffee beans, roasting, grinding, and brewing is very important. Likewise, the container used to hold it - the coffee mug is also very important. If it is properly matched, it will have an icing on the cake effect. The following are the methods and steps of using coffee mugs introduced by China ceramic mug factories:

1. The material of the coffee mug

The simplicity of ceramic mugs and the roundness of porcelain mugs symbolize different coffee attitudes. The ceramic mug has a rich texture and is suitable for dark roasted and full-bodied coffee. Porcelain mugs are light in texture, soft in color, high in density, and good in heat preservation. They can make the coffee cool down more slowly in the mug, and are the best choice for expressing the flavor of coffee.

2. The size of the coffee mug of the coffee mug

Small coffee mugs (60ml~80ml) are suitable for tasting pure high-quality coffee or strong single-origin coffee. The size of a mug can make the aftertaste of the coffee linger and show the delicate flavor of coffee.

Regular coffee cups (120ml~140ml), common coffee cups, generally choose such cups when drinking coffee, there is enough space, you can make your own, add milk powder and sugar.

Mug (above 300ml), suitable for coffee with a lot of milk.

3. Placement and warming of coffee mugs

Placement method: There are two kinds, the handle of the mug is on the right is American style, and the handle of the mug is on the left is British style.

Warm mug: Warm the ceramic coffee mug in order to completely seal all the flavors of the coffee. The easiest way to do this is to pour hot water into a ceramic coffee mug, or to preheat a coffee mug in the microwave. Because once the boiling coffee just out of the oven is poured into a cold mug, the temperature will drop suddenly, and the aroma will also be affected. In order to best retain the aroma of coffee, it is best to serve coffee in a hot ceramic coffee mug.

4. Clean ceramic coffee mugs

Ceramic coffee mugs with fine texture have compact surface and small pores, which are not easy to adhere to coffee stains. After drinking coffee, it is best to rinse with clean water immediately to keep the cup clean.

In ceramic coffee mugs that have been used for a long time, coffee stains will adhere to the surface of the mug as it accumulates over time. For ceramic coffee mugs with stubborn coffee stains like this one, soak the mug in lemon juice or lye water to remove coffee stains. In the process of cleaning the coffee mug, never use a hard brush to scrub, and avoid using strong acid and alkali cleaners. The surface of the coffee mug is scratched and damaged, which will affect the taste of the coffee.
