Characteristics and production process of ceramic drum mugs

Xinxiang custom ceramic mug manufacturer, ceramic drum mugs are made because they are shaped like a drum. the diameter of the body of a ceramic drum mug is larger than the diameter of the bottom of the mug. what are the characteristics of ceramic drum mugs and how are they made?

1. Appearance of ceramic drum mugs

1). Material

Durability: Ceramic drum mugs are made of high-temperature fired clay, which is strong and durable and can be used frequently.

Insulation: Compared with other materials, ceramic has good heat insulation properties, which can keep drinks hot or cold for a long time.

2). Shape and size

Drum shape: These mugs are usually cylindrical, reminiscent of a drum, giving them a unique artistic touch.

Variety of sizes: There are a variety of sizes to choose from, from small espresso cups to large coffee mugs, to meet different drink preferences.

3). SAFETY

Food safe: Ceramic mugs made with safe glazes are safe to drink from, and even better for hot coffee.

Heavy feeling: Ceramic mugs usually have a solid and heavy feeling, which makes people feel that they are of high quality and very stable when filled.

2. Features of ceramic drum mugs

1) Ceramic drum mugs can't be made by conventional pressing method because of the curvature of the mug body. Therefore, ceramic drum mugs are mostly made by injection method. However, there is a kind of fat ceramic mugs, the body of which is also curved, and it is made by pressing method. It is different from ordinary ceramic drum mugs, the main difference is that the mouth of fat ceramic mugs is bigger.

2). Ceramic Drum Mugs Because of the larger capacity and heavier mugs, ceramic drum mugs are mostly made of stoneware. In this way, ceramic drum mugs are heavier in the hand, with better heat insulation and heat preservation.

3) Ceramic drum mugs are baked with high temperature.

4).The pattern of ceramic drum mugs is determined according to the customer's demand for the pattern. They can be divided into high-temperature and low-temperature patterns. (For detailed information, please refer to: Ceramic flower paper classification and characteristics of appreciation.)

5).Ceramic drum mugs are suitable for microwave and dishwasher. This depends mainly on the type of flower paper. If it is a high temperature flower paper or ceramic drum mugs with a solid colour glaze without a pattern. ceramic drum mugs are safe for microwave and dishwasher use. （What kind of ceramic coffee mugs are not dishwasher and microwave safe?)

3.The process of making ceramic drum mugs

1). Moulding

Before closing the mould, the working surface of the model should be cleaned up, no dry mud or dust should be left. And check whether the working surface of the mould is smooth and clean, with or without holes and lubricant traces. If it is normal, the mould can be closed. If there is a big gap in the assembled model, use soft mud to block the gap at the joints to avoid leakage of slurry. When using the model should not be too dry or too wet, the amount of water is generally controlled at 4% -6%.

2). Grouting

For single-sided grouting, the slurry filled model can be, such as mud layer thickening to the required thickness, pour off the model of excess slurry, in order to avoid pouring off a small amount of residual slurry in the billet in the body of the surface of the uneven distribution of the production also need to pour off the slurry after the billet with a billet model for the dumping of slurry to ensure that the distribution of residual slurry to ensure that the distribution of mud is uniform to avoid mud wisps. For double sided grouting, the grout must be replenished one after another until all the cavities in the model become blanks. There is no need to pour and dump the slurry.

3). Drying

Just formed due to the high water content, low strength and can not immediately release the injection, need to take the mould to dry for a certain period of time, this drying is called green billet drying, in the green billet drying period, due to the evaporation of water and the mould continues to absorb water, the injection of the water continues to decline, the billet contraction and detachment of the model, and at the same time gradually increase the strength, then can be removed from the mould.

4). Demoulding

After demoulding, the blank should be held gently, put flat, put right, put stable, and prevent vibration.

5). Bonding

Bonding is for ceramic cups and other blanks can not be formed in one piece of the necessary process, the bonding process refers to the use of a certain consistency of bonding mud cups and mugs to stick together in the process.

6). Repairing

For the bonding of ceramic drum mugs, due to its surface is not very smooth, the edge of the mouth has a burr, and some still have a mould seam trace, the need for ceramic cups for beautification, this step is called repair blank. Repair blank is a necessary work of injection moulding ceramic mugs. We usually see flat, smooth ceramic coffee mugs, mainly because of trimming. There are wet repair and dry repair ceramic drum mugs using wet repair. Wet repair is a lot of water in the blank, still wet and soft case, suitable for more complex shape or need to be wet by the blank, this time the operation is easier and repair of blanks, the disadvantage is that it is easy to move and operate in the process of the blanks are injured and caused by deformation. China ceramic mug factory since 2022 are using automatic repair machine, not only can improve the efficiency of repair, but also improve the quality of repair, eliminating the deformation of the repair. (For more detailed information on making ceramic mugs by grouting, please refer to: Customised Ceramic Coffee Mugs - Grouting Process Explained)

7). Glazing

The completely dried mugs are glazed. There are many different types of glazes (Glaze Composition and Classification). The easiest glaze to apply is a single colour glaze, in which the whole of the moulded mug is placed in the glaze. If the mug requires multiple glaze colours, then the operation is a little more complicated. An example is the common two-colour glazed mug - one colour on the outside and another on the inside. The glazing process for a two-colour glazed mug is as follows:

a). The mouth of the mug is glazed. The mouth of the mug is where the two colours join, so it needs 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 is dipped in the mouth of the mug should be filled with a water-resistant agent.

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

c). Outer wall glazing. Place the dried mug into the glaze liquid, called dip glaze in the industry.

8). Firing.

After drying the glazed mugs, they can be fired in the kiln. The time is more than 10 hours, depending on the type of mug. In addition, according to the customer's requirements for the colour of the mug, there are high temperature firing, medium temperature firing and low temperature firing.

9). Out of the kiln

After the ceramic drum mugs are fired, they will be quality checked and packed after leaving the kiln (How to pack the ceramic mug so that it will not be damaged?).

Ceramic drum mug factory combine functionality with artistic design, making them a popular choice for beverage containers. Their unique mug shape determines the raw materials used to make them, the production process and the firing temperature.

To sum up, stoneware mugs are different from coffee mugs made of white porcelain mugs and bone china mugs because of the different raw materials and baking temperatures. Stoneware mugs are characterised by their resistance to wear, heat and high temperatures. Stoneware mugs are indistinguishable when covered with glazes and prints. Stoneware mugs do not differ much from coffee mugs made of other materials, so there is no need to determine what this type of coffee mug is made of in everyday use. Our concern when using a coffee mug on a daily basis is whether it can be used in the dishwasher and microwave. Whether a coffee mug can be safely adapted for dishwashers and microwaves depends largely on the flower paper of the mug. Stoneware mugs with high temperature decals and high firing temperatures are able to be used in microwaves and dishwashers.

Are the sublimation mugs dishwasher and microwave safe?

Xinxiang custom ceramic mug factory, sublimation mugs are widely popular, which stems from the advantages of sublimation mugs. So, what are the advantages and disadvantages of sublimation mugs, and is it safe to use in dishwashers and microwaves? Xinxiang ceramic manufacturer, give you a detailed introduction to sublimation mug.

1.What is sublimation mugs

Sublimation mug is also called coated mug, it is a kind of mug specially used for heat transfer printing. It can make our photos, our own patterns, conveniently printed mugs. As we all know, ordinary mugs can't do heat transfer. Because ordinary mugs do not have a coating on them, sublimation mugs are a kind of mugs that are specially used for heat transfer printing. So, our pictures or designs can be printed on the mugs. So how is it that sublimation mugs are able to accomplish the transfer of pictures? There are several important materials and a special process. Firstly, there is a special coating on the surface of the mug, hence the name coated mug. Secondly, the flower paper and ink for heat transfer printing are not ordinary. On the basis of these two hard materials, the heat transfer machine is needed to print the pattern onto the mug.

2. Advantages of sublimation mugs

a.Strong personality

Sublimation mugs have rich colours and designs, and strong personality because its pattern printing process is easy to operate.

b. Strong heat preservation

Because sublimation mugs with the cup type are ordinary mugs, so sublimation mugs are strong insulation.

3.Disadvantages of sublimation mugs

a.High price

Because of its printing process, the sublimation mug is more expensive than ordinary mugs.

b.Poor pattern solidity

The characteristics of heat transfer printing, although the pattern printed onto the mug is easier and the temperature is low when transferring. Therefore, sublimation mugs have poor pattern solidity, which can easily lead to pattern damage in dishwasher and microwave.

4. Production characteristics of sublimation mugs

The difference between sublimation mugs and ordinary mugs is mainly in the wall of the mug. Sublimation mugs are also called coated mugs, and their main feature is a layer of coating on the outer wall. Dip the ceramic mug into the coating solution and tilt it out to dry after it is completely coated. Clean the surface of the mug with a flannel, wrap the transfer paper around the mug, fix it with high temperature tape, put it in the mould cavity of the hot cup stamping machine, the set temperature is usually around 200℃, and carry out the heat transfer printing of the pattern.

5. Whether the sublimation mug can be used in dishwasher and microwave oven

Because the sublimation mug coating, flower paper and printing process issues. The dissolving temperature of its flower paper is around 200℃, so the high temperature microwave oven can destroy its pattern. Because the sublimation mug flower paper is not fired at high temperature, the flower paper and glaze do not form a protective film similar to glass, so the picture is also easy to be damaged in the dishwasher. Therefore, sublimation mugs are not suitable for dishwashers and microwave ovens.

Sublimation mugs have a strong personality because they are easy to print patterns on. However, because of this problem, it is less stable than the screen of printed ceramic mugs fired in large kilns. China ceramic mug factories think sublimation mugs are not suitable for microwaves and dishwashers.

Xinxiang custom ceramic mug manufacturer, the objective of the study was to quantity by descriptive analysis the impact of mug shape (Short/Wide vs. Tall/Narrow) and beverage volume (100, 150, 200 and 250 ml), systematically combined to obtain eight conditions, on the perception of instant coffee. To obtain exhaustive conclusions, the experiment was repeated with four coffee types prepared by combining two coffee species (pure Arabica and pure Robusta) and two powder concentrations (0.8 g/100 ml and 1.6 g/100 ml). The 32 beverages (8 conditions × 4 coffee types) have been profiled sequentially by 11 trained assessors using a glossary of 59 attributes covering appearance, orthonasal aroma, retronasal aroma, taste, mouthfeel and aftertaste perceptions. Results show that conditions significantly impact darkness intensity of all coffee types but high dosed Robusta. This modulation of darkness is not associated with any other significant modulation of perception, except for low dosed Arabica, for which significant changes in darkness are associated with significant changes of four orthonasal attributes (overall aroma intensity, aroma complexity, roasty and malty). It is noteworthy for coffee industry to observe that sensory quality of reconstituted instant coffee was stable across mug and volume conditions for three coffee types. Nevertheless, for low dosed Arabica, the different conditions modulated ortho-nasal perception of aromatic notes probably through crossmodal interactions induced by changes in liquid coffee darkness intensity. Coffee professionals thus need to take into consideration that coffee mugs and cups may affect consumers’ perception of certain coffee types.

The impact of packaging and vessel physical properties on food and beverage sensory expectations and how such expectations modulate sensory experience has largely been investigated in the past decades (Piqueras-Fiszman and Spence, 2015, Spence and Wan, 2015) mainly with respect to colour and shape properties.

The role of colour on consumers’ expectation and/or perception of food and beverage has been largely demonstrated. For instance, expectation for sweetness in orange juice is higher when packaging background colour was orange compared to white (Deliza, Macfie, & Hedderley, 2003). This probably results from learnt perceptual association between orange colour and sweetness which reinforced expectation for sweetness. The white colour of a plate increased actual sweetness of a strawberry mousse in comparison to a black plate (Piqueras-Fiszman, Alcaide, Roura, & Spence, 2012). According to the authors, the white background may have enhanced the perceived pinkness of the mousse though contrast effect and then perceived sweetness of the dessert through crossmodal visual-taste interactions due to congruency between pink colour and sweetness. The impact of mug colour on expected and actual perception of coffee beverage consumers’ perception has been demonstrated and explained by crossmodal interactions between taste and colour, e.g. pink ceramic mugs increased coffee sweetness and reduced acidity compared to white cup (Carvalho & Spence, 2019). However in another study perceived sweetness of coffee was decreased when experienced in white ceramic mugs vs transparent and blue cups (Van Doorn, Wuillemin, & Spence, 2014). Indeed, according to the author, the perceived brownness being more intense in the white cup probably through contrast effect, this may have, in turn, increased the perceived coffee flavour and then reduced the perceived sweetness.

Multiple studies explored the impact of shape of container on food and beverage perception (Spence & Van Doorn, 2017). More fruitiness for beer in curved-sided vs regular glass was perceived by consumers because the rounded shape may have evoked the roundness of many fruits (Mirabito, Oliphant, Van Doorn, Watson, & Spence, 2017). Rounded coffee mugs further enhanced the perceived sweetness of coffee (Carvalho & Spence, 2018). Indeed some perceptual associations have been demonstrated between container shapes and basic tastes such as round shape and sweetness (Velasco, Woods, Petit, Cheok, & Spence, 2016). An on-line study using mug pictures with different diameter, height, and thickness of rim showed that expected bitterness, taste intensity and aroma strength of coffee were rated higher in short than in taller mug and in small than in large diameter mug (Van Doorn et al., 2017). According to the authors, cultural influence could explain such results as coffee served in short mug are in some countries more concentrated and then “stronger” (e.g. espresso) whereas in larger mug coffees are often more diluted and/or served with milk and then less “strong”. To summarize colour and shape of the container can create sensory expectations resulting from crossmodal implicit associative learning occurring during repeated eating experience as reported for odour and taste modalities (Stevenson, Boakes, & Prescott, 1998). Such sensory-based expectation can, in turn, modulate food and beverage sensory perception. For a review of the role of visual cues on expectation and its impact on actual perception see Deliza and MacFie (1996).

Descriptive analysis method encourages trained panelists to apply an analytical strategy by evaluation sensory attributes independently. However, because of the robustness of perceptual associations implicitly stored in our memory (Mojet & Köster, 2005), we hypothesized that the impact of container physical properties on consumers’ beverage and food perception also influence descriptive analysis results obtained with a trained panel. We tested our hypothesis on coffee beverage served in Short/Wide vs. Tall/Narrow rounded white ceramic mugs in porcelain which are regular mugs suitable for sensory evaluation. China ceramic mug manufacturers, Based on finding from Van Doorn et al. (2017) showing that both height and diameter modulated sensory expectations, we predicted that coffee perception is modulated by the shape of a mug and that aroma and bitterness are perceived more intense when evaluated in mug with Tall/Narrow shape compared to Short/Wide shape which is associated to more diluted and then less intense coffee and such impact is reinforced with low beverage volume which is associated to more concentrated and then more intense coffee by opposition to larger beverage volumes.
