Ceramic mug orange peel glaze phenomenon research and solution

Xin xiang custom ceramic mug manufacturer, many ceramic mug buyers get ordered mugs, its body is not smooth, (exceptions for special needs such as frosted mug, matte mug, etc.). Ceramic mugs like this, in fact, belong to the unqualified products. China ceramics factory stands in the producer's point of view, for ceramic mug surface appears similar to the unevenness of the orange peel phenomenon (commonly known as “orange peel glaze”), to explain the reasons for its formation. The main reasons include: glaze formula, firing process and billet quality.

1. what does orange peel glaze look like?

Imagine the skin of a fresh orange: covered with tiny bumps, uneven to the touch. Ceramic mug if the appearance of orange peel glaze, looks like the orange peel “printed” on the cup. Specific performance: surface roughness: the original should be smooth surface of the mug appeared wavy undulation; dull luster: like a layer of mist, reflective effect is poor; feel bad: finger scratching can obviously feel the grain. This defect not only affects the beauty of the ceramic mug, but also reduces the grade of the cup, and even lead to serious glaze flaking.

2. Why does orange peel glaze?

Ceramic mugs appear orange peel glaze phenomenon, very similar to our failure to do the cake. When making a cake, if the quality of the cream, flour problems, or baking temperature is not controlled, it is easy to make a failed cake. The orange peel glaze of ceramic mugs is also due to the glaze and firing process.

2.1. glaze viscosity

In the previous article about ceramic mug glaze (Instructions for making glaze in ceramic mugs), we introduced. Before a glaze is put into the kiln and fired, it is a paste-like liquid. When a mug is coated with glaze and fired in a kiln, it becomes a smooth “glass layer” on the surface of the mug. The role of kaolin in the glaze, play the role of the binder. The glaze paste adjusts the viscosity of the glaze by adjusting the content of kaolin and water. If the proportion of kaolin exceeds 15%, then its viscosity is too strong, and the phenomenon of orange peel glaze will easily appear. If the glaze is not finely ground enough, the diameter of the particles inside is too large. Then, such a ceramic mug will be covered with fine bumps, feel uneven, and have a poor luster.

2.2. Glaze too thick

Ceramic mug glazing process, we have talked about it before. It is mainly divided into: dip glaze, spray glaze and brush glaze. In the glazing process, whether the glaze is uniform, can lead to ceramic mug flow glaze. Similarly, whether the glaze thickness meets the requirements also determines whether the mug will appear orange peel glaze phenomenon. If the glaze is applied too thinly, especially with darker colors, you will notice that the mug will have a vaguely ceramic undertone. If the glaze is applied too thickly, exceeding the safe thickness of 0.25 mm, the ceramic mug will be prone to orange peel glaze.

2.3. Firing

The firing process is what transforms a mug from “clay” to “ceramic”. In the previous article, we introduced the firing process of various equipment, temperature and humidity control (In-depth analysis of the firing process of ceramic mugs) . So, how does the firing process lead to the orange peel glaze on ceramic mugs? Mainly because: in the heating stage, the heating speed is too fast or missing insulation stage, resulting in the glaze is not uniformly melted on the beginning of solidification; another reason is that the kiln does not reach the high temperature of the glaze melting (for example: the kiln is no longer warmed at 1250 ℃, resulting in the glaze is not completely melted); the last reason is that the kiln is too fast to cool down, high-temperature heat preservation time is not enough, resulting in the glaze suddenly shrinkage caused by the orange peel glaze phenomenon.

2.4 Failure of Raw Billet

In addition to the above 3 reasons, leading to the phenomenon of orange peel glaze, there is another kind of ceramic mug raw billet reason. Glaze, glaze, firing, these three processes are acting on the ceramic mug billet. Ceramic mug raw material if the iron content is higher than 1%, iron and glaze will produce exclusion reaction, the phenomenon of orange peel glaze. If there is dust on the surface of the ceramic mug raw billet, resulting in reduced glaze adhesion during the glazing process, will also produce the phenomenon of orange peel glaze.

3. How to solve the orange peel glaze

According to the practical experience of China ceramic factory, the following measures can reduce the incidence of orange peel glaze from 20% to 3%:

3.1 Improve the glaze formula

Add “lubricant” to the glaze - borax and lithium faience, used to stabilize the viscosity of the glaze. In the powdering stage of the glaze material, the precision and grinding time of the ball mill should be ensured, and in the sieving stage, the fineness of the glaze material should be ensured. In addition, the use of stable quality raw materials, pay special attention to the content of iron and sulfur.

3.2 Control glaze application

At present, China ceramic factory adopts automatic glazing assembly line to make the glazing process and quality inspection more rigorous. Through the automated assembly line, the glazing process is guaranteed to be uniform, and the glaze thickness error is within 0.01mm. Through this, the glazing process of ceramic mugs is guaranteed to be problem-free.

3.3. Kiln automation

China's previous kilns were mostly based on traditional kilns, and the firing process was mainly dependent on the experience of the technicians. Nowadays, kilns use automation from fuel to temperature control. The heating up time, firing temperature, holding time and cooling down process are precisely controlled by computer.

3.4. Clean Raw Billets

The ceramic factory itself is with the concentration of clay and ceramics, so the production plant is relatively dusty. Ceramic mugs need to be dehumidified and dried after the production of raw blanks (Drying and trimming process of ceramic mug clay blanks). Raw billet in the drying stage, it is inevitable to fall on the dust, in the later part of the glaze link will be prone to problems. Ceramic factory for this problem using measures are mainly, control the environment of the drying plant; glaze before the use of air guns to clean the billet.

4. Frequently Asked Questions

Q1：Home to buy a mug with orange peel glaze, can I still use it?

A: Mild orange peel glaze does not affect the use, but heavy may lead to glaze off, it is recommended to replace.

Q2：How to judge the orange peel glaze with naked eyes?

A：Rotate the mug to the light, the smooth glaze will reflect evenly, and the orange peel glaze will have bright and dark ripples.

Q3：Why do some handmade mugs intentionally do orange peel effect?

A: The deliberately created texture is different from the defects, which are usually evenly distributed and treated with anti-peeling.

By understanding the glaze characteristics and controlling the production process, orange peel glaze can be completely avoided. This is not only a technical problem, but also a test of craftsmanship - China Ceramics Factory strives for excellence in every link in order to guarantee that every mug is smooth as a mirror and warm to the heart.

Instructions for making glaze in ceramic mugs

Xinxiang custom ceramic mug manufacturer, ceramic mug production process, clay through a number of processes (practicing clay, billet molding, drying and billet, plain firing), ceramic mugs will enter the “make-up” stage. Ceramic mug beautification is mainly through the glaze and flower paper to achieve. Custom ceramic coffee mugs, buyers of ceramic factory mentioned one of the main needs is the color and picture. The color of the mug is achieved through the glaze, and the picture of the ceramic mug is done through the flower paper. Today, China ceramic factory first to tell you about the glaze. What is glaze? The color of the cup requested by the customer, China Ceramic Mug Manufacturer is achieved through which process?

1. What is the glaze? How to make it?

1.1 Glaze is like “paint”.

The glaze is a paste-like liquid before it is put into the kiln to be fired. Ceramic mugs coated with glaze, put into the kiln firing, it becomes a smooth layer of the surface of the mug “glass layer”. The purpose of the glaze is waterproof, beautiful and durable.

1.2 How is the glaze made?

a. Matching raw materials: according to the color requirements of the custom ceramic coffee mug, ceramic factory will find out the corresponding color value. We prepare the raw materials (including: quartz stone, feldspar, kaolin and other materials) according to the formula.

b. Powdering: The ceramic factory pours the mixed raw materials into a ball mill (a barrel-shaped machine with many small stone balls inside). Add water and grind into a fine powder slurry (like soybean milk, grind until there is no graininess to the touch).

c. Sieve: Use a fine mesh to sieve out large particles to ensure that the glaze paste is fine.

d. adjust the concentration: in accordance with the recipe, add water and adjust to a little thicker than milk state (too thin to hang the mug, too thick will crack).

e. Storage glaze paste: loaded into a vat, regular stirring to prevent precipitation.

1.3. Glaze storage precautions

a. Anti-drying: the bucket holding glaze paste should be sealed, otherwise the surface caking (like soybean milk put for a long time peeling).

b. Anti-freezing: glaze paste can't be put outside in winter, glaze paste will be stratified after freezing.

c. Shelf life: glaze paste in sealed and room temperature, do not store more than 3 months, otherwise it will deteriorate (glaze paste will smell or hard lumps).

d. Safety: glazes containing lead and cadmium should be labeled separately.

2. the role of each component in the glaze

2.1. quartz (sand): glaze raw materials account for the most quartz, can account for more than half. Quartz is the glaze “skeleton”, it is in the glaze after firing, can make the glaze hard.

2.2 Feldspar: it is a natural “accelerant”, it allows the glaze to melt at low temperatures, its main role is to reduce the melting point of the glaze.

2.3. Kaolin: It acts as a binder, which allows the glaze to stick firmly to the mug.

2.4. Metal Oxides: The color of the glaze is determined by the metal oxides. The color of the glaze varies according to the amount of metal oxides added. For example, if iron oxides are added to the glaze, the glaze takes on a yellowish-brown color; if cobalt is added, the glaze turns blue; if copper is added, the glaze turns green.

2.5. opalizing agents: for example, tin dioxide, which whitens and makes the glaze opaque, giving it a white color.

3. The difference between high temperature glaze and low temperature glaze

Customized ceramic coffee mugs, ceramic factory will habitually ask buyers: “need to be made into high temperature glaze ceramic cups, or made into low temperature glaze ceramic cups?” Many buyers for high temperature glaze and low temperature glaze is not clear, the difference between the two and the advantages and disadvantages are not understood. Then, China ceramic factory to make both clear.

3.1. High-temperature glaze, is the firing stage, which requires a higher temperature (1280 ℃ or more) for firing. It requires a higher temperature, then the more energy consumed in the firing process, so the cost of production is also high. This high-temperature glaze is more wear-resistant and environmentally friendly (it does not contain lead or chromium). Ceramic mugs with high temperature glaze last longer and are safer. However, high-temperature glazes cause many colors to be less vibrant than low-temperature glazes because of the high temperature.

3.2 Low-temperature glaze refers to the firing stage, only need a relatively low temperature (about 800 ℃) can be made. Low-temperature glazes require low temperatures, so less energy is needed in the firing process, and the production costs are lower. This low-temperature glaze guarantees the vividness of the colors and takes less time to produce. However, this kind of low temperature glaze has poor abrasion resistance and is more easily scratched.

4. How to judge the quality of glaze

4.1. After the sample coated with glaze in the test firing, through the test finished glaze, to judge the quality of the glaze. Sample glaze surface if smooth, no cracks, no pinholes, then the quality of this batch of glaze paste is qualified. On the contrary, this batch of glaze paste is unqualified.

4.2. by knocking the sample, by virtue of the sound to determine the quality of the glaze. Tap the sample to listen to the sound, if the sound is crisp, then you can judge the adhesion of the glaze is qualified. If the sound is muffled, then the adhesion of the glaze is not qualified.

4.3. Immerse the sample in an acid solution for 24 hours. After immersion, watch for changes in the glaze. If there is no change, the glaze paste is qualified, and vice versa.

5. Glaze precautions

5.1. formula: the same color, different factories, the production of ceramic mugs, the color is different. Mainly is reflected in different formulas, formulas and personnel is a qualified, stable ceramic mug factory, the cornerstone of survival.

5.2. Inspection: After the glaze paste production is completed, it should be regularly stirred and inspected. Prevent the glaze paste from deteriorating and settling.

5.3. Firing: high-quality finished ceramic mugs, not only rely on good quality glaze paste, in the firing, but also need to strictly control the firing process. Otherwise, the glaze will not be bright; low temperature glaze over temperature will flow glaze.

3 characteristics of advertising ceramic mugs

Xinxiang ceramic mug manufacturer, Three characteristics of advertising ceramic mugs: first, practicality; second, advertising. Third, the cost is low.

As far as the mug is concerned, its practicality is that it is a commonly used drinking utensil when people drink water, especially for enterprises and institutions. Its advertising nature lies in its mug body space, the mug body is adjusted according to its specifications, the mug body area is adjusted accordingly, but if an ordinary mug is disassembled from the middle and expanded into a fan shape, it is operable, that is The putable area is completely beyond your imagination.

There is also the fact that in the daily use of the mug, it is impossible to lift the mug 3 meters away. The close contact between the mug and the person makes every word and every figure on the mug, even if it is small. , Can always become the focus of vision.

In addition, for the branded mug, in real life, when someone is really holding it, it is definitely not limited to the moment of drinking water. You can completely imagine that when you are chatting with people, when you are in a daze, when you are resting, at almost any moment, the mug can always be a prop for you, me, or him in any posture, or hold, reward, or wave with gestures. Or be stared deeply...Of course, you can also imagine that you have stared quietly at a newspaper advertisement until the thing is forgotten, and the soul is out of your body? Finally, the production of advertising mugs has a short cycle and low cost. Ordinary space mugs can be done for about ten dollars, and a better thermos mug is only a few dozen, which is also very suitable for customers. Compared with the advertising effect that can be achieved, the cost is very small.

What do the 6 boxes on the custom Starbucks coffee mug mean?

 From Xinxiang Custom Ceramic Mug Manufacturer, Friends who often go to Starbucks will find that there are a series of boxes on the side of custom Starbucks mugs, and each box has a corresponding note. Whenever you order coffee, the cashier will draw a sketch in the box. So what is the meaning of each of these boxes? How to order coffee at Starbucks, today I will help you popularize it!

The first box: Decaf; the full name is "Decaffeinated", which means decaffeinated. If you want to drink coffee but don't want caffeine, then you can mention that you want Decaf when you order Coffee, if you order Decaf coffee, usually the cashier will put an X in the box as a mark for the barista.

The second box: Shots; actually refers to the number of espresso servings in a cup of coffee drink. Usually there is only one shot of espresso in a coffee drink, but you can propose double espresso mugs, or three espresso It's the way to ask for it. If you ask for a few more shots, you will be charged the corresponding price. So when you ask for more shots, the cashier will write the corresponding Arabic numbers in the box for coffee. Mark of the division.

The third box: Syrup; the so-called Syrup actually refers to adding flavored syrups of different flavors to the coffee according to the needs of customers, usually caramel, hazelnut and vanilla. Of course, Starbucks, as the leader of modern coffee fashions, launches a cat's claw mug that will allow many people to queue up or even fight. Its R&D capabilities cannot be underestimated. So every once in a while, Starbucks will launch different flavors. For the new syrup, when you request to add a certain syrup, the cashier will write the acronym corresponding to the syrup in the box. For example, for vanilla syrup, write a capital "V" as a sign to the barista.

The fourth box: Milk; Milk is probably the most easily overlooked detail for us Chinese. The general public's perception of milk is usually very general. This is because the classification of dairy products in our country is not so rigorous, in fact, in Europe and America In the country, milk can be divided into many types, and in Starbucks, all your needs for different milk can be basically met. How many types of milk are added to coffee? In fact, there are 4 types, namely whole milk, low-fat milk, skimmed milk, and soy milk. When ordering, you can use the "type of milk + coffee name" method to request different milk choices. When you request the type of milk, the cashier will write the corresponding letter abbreviation in the box. For example, skim milk will write N, and soy milk will write S to inform the barista.

The fifth box: Wholesale Starbucks mug; refers to the special requirements made by customers when ordering. The most common requirements are temperature requirements. Coffee can generally be hot or iced, but if you like very hot coffee, you can also Extra heat can be requested. In addition to temperature, you can also request the amount of milk froth, and you can also request to add some additives such as chocolate chips. When you have a temperature requirement, the cashier will write the corresponding letter abbreviation in the box, such as H Represents heat, and Ice adds a bar to represent iced coffee to go to ice.

The sixth box: Drink; refers to the type of coffee drink ordered by the customer when ordering. When you order the coffee drink, the cashier will write the corresponding letter abbreviation in the box, for example, latte will write L, American coffee will write A etc.

Starbucks Mug Manufacturers coffee drinks usually come in three sizes: the medium cup is called Tall, the large cup is called, the large cup and the extra large cup.

How custom ceramic coffee mugs with different mouth in China ?

 From Xinxiang China Ceramic Mug Manufacturers,The taste of a mug of coffee is affected by many factors, including the type of coffee beans, origin, roasting method, etc., but did you know that coffee mugs also affect the taste of coffee?

Mugs with different mouths

There are two types of coffee mugs: wide-mouth mug and straight-mouth mug. The shape of different mugs will directly affect the feel and flavor of the coffee you drink in the first sip.

Custom Wide mouth coffee mug

The wide-mouth mug, as the name suggests, is a mug with a wider mouth. Expanding the mouth of the mug allows your taste buds to fully contact the coffee, and your tongue can feel the flavor of coffee more completely.

Straight coffee mug

Wholesale Straight mouth mug, as the name implies, is that the mouth of the mug is straight. The mouth of this mug is perpendicular to the table top, and the coffee liquid is more concentrated when entering, and the taste is more balanced(Ceramic mug suppliers).

In summary, although coffee mugs will have a certain impact on the flavor of coffee, we do not choose coffee mugs to choose the best, but to choose the most suitable coffee mug that can amplify or concentrate the flavor characteristics you like The cup, because for more people, a cup of coffee is a mood.

Different color ceramic coffee mugs, different taste - China mug manufacturers

 From Xinxiang Ceramic Mug Manufacturers,Psychologists believe that people's first feeling is vision, and the biggest impact on vision is color. The reason why people's behavior is influenced by color is that people's behavior is easily dominated by emotions.

Therefore, the color of the custom ceramic coffee mugs, will also have a certain impact on people's mood, and then affect the judgment of coffee taste.

Duolun, as like as two peas in the University of Australia, has invited dozens of people to do experiments, and the same coffee is placed in different color coffee mugs to test the effect of coffee mug color on people's taste of coffee.

The results show that, compared with transparent glasses, people think that the color of the coffee in the white ceramic coffee mugs is darker, and that the concentration is higher and the taste is more bitter; while for the coffee in the blue coffee mug, due to the blue contrast, people think that the color of the coffee liquid is lighter, and then they think that the coffee liquid has low concentration and does not taste bitter.

Therefore, the color of the ceramic coffee mugs will more or less affect the taste.

Production technology of printed ceramic coffee mug from China manufacturers

 From Xinxiang China Ceramic Mug Manufacturers,Color glaze ceramic mugs is the cup with color. Black, red, blue, yellow, etc. belong to color glaze cup. Because these cups have a deeper color as the background color, they can't directly print other colors on the polyvinyl butyral film to make flower paper. Instead, the white background color must be printed on the polyvinyl butyral film first, and then on the white background color, the printing needs to be printed Other colors, so as to ensure that the color of the paper will not be covered by the background color of the cup during the baking process.

In the process of baking flowers, the custom color glazed mugs also needs special wiping treatment, because the polyvinyl butyral film of flower paper is easy to remain on the surface of the color glaze cup, and a circle of film imprint can not be wiped off. The appearance of this layer of film printing is due to the deep background color of the cup, and the polyvinyl butyral film printing is white, so it is particularly obvious under the background color of the cup When baking flowers, the film seal has been baked into the glaze of the cup, so it is meaningless to wipe the film seal at that time.

Therefore, to get rid of the film printing, you must wipe the cup completely after the hand-made decal. After the cup is baked, you must immediately wipe it again. In this way, you can clean the film printing.

In fact, there are many wholesale ceramic coffee mugs that need some special treatment when printing, or special processing when printing paper. We will introduce them one by one in order to discuss with you.
