Raw materials for making stoneware mugs constrain dishwasher and microwave use
Xin xiang Ceramic Mug Manufacturer, Stoneware mugs are a high quality ceramic product that is characterised by wear resistance, heat resistance and good thermal insulation. On the market, stoneware mugs can be customised in a variety of ways, such as heat transfer and logo printing.
High Strength:
Stoneware mugs are fired at high temperature, which has high strength and durability and is not easy to break.
Good heat retention:
Due to its high density, stoneware mugs can effectively keep the temperature of drinks, suitable for both hot and cold drinks.
Abrasion Resistance:
Smooth surface, wear-resistant, long service life.
Aesthetics:
Stoneware mugs usually have a beautiful appearance and rich colour options, suitable for various occasions.
Non-toxic and harmless:
Made of natural materials, no harmful substances, safe and healthy.
Easy to clean:
The smooth surface makes stoneware mugs easy to clean, not easy to retain dirt.
Adaptable:
Can be used for a variety of drinks, such as tea, coffee, milk, etc., suitable for home and office environments.
These features make stoneware mugs a popular beverage container for daily use and gift giving.
The raw materials of stoneware mugs mainly include: kaolin, quartz sand, feldspar and limestone. The choice of these raw materials is crucial to the quality of stoneware mugs.
Kaolin: as the stoneware production of basic materials, kaolin has a high degree of whiteness, high quality features, its composition is relatively stable, not easy to deteriorate, can ensure the stability of stoneware mug materials and quality.
Quartz sand: quartz sand has the characteristics of high hardness and light colour, which can improve the hardness and abrasion resistance of stoneware mugs after firing, making them more durable.
Feldspar: Feldspar is used to regulate the chemical composition and firing temperature during the production of stoneware mugs, and helps to develop the unique physical and chemical properties of stoneware mugs.
Limestone: Limestone is also used to regulate the chemical composition and firing temperature of stoneware mugs, and has an important influence on the firing process and final properties of stoneware mugs.
In the proportion of raw materials, generally adjusted according to the specific production needs and process requirements, but the common ratio is roughly 40-50% kaolin, 25-30% quartz sand, feldspar accounted for 20-25%, limestone accounted for 5-10%.
Stoneware mug production process is tedious and delicate, mainly includes the following:
1). Raw material preparation: the kaolin, quartz sand, feldspar and limestone and other raw materials in accordance with a certain proportion of mixing, and after grinding, sieving and other processes to ensure that the fineness and uniformity of raw materials.
2). Moulding: The mixed raw materials are moulded into stoneware mugs by pressing, grouting or billeting. The moulding process needs to control the thickness and shape of the blank to ensure the quality of the final product.
3). Drying: the moulded blanks are placed in the drying room for drying treatment to remove the moisture and organic matter in the blanks. Temperature and humidity need to be controlled during the drying process to avoid cracking or deformation of the blanks.
4). Glaze: Apply a thin layer of glaze on the dried blank. The choice of glaze needs to take into account the use of stoneware mugs and decorative effect. The glazed blanks need to be dried for subsequent firing.
5). Firing: the glazed blanks into the kiln for high temperature firing. Stoneware firing temperature is generally between 1140-1280 ℃, than the ordinary ceramic firing temperature is about 150 ℃. The firing process needs to control the temperature and atmosphere of the kiln to ensure the vitrification degree of stoneware mugs and various performance indicators.

Material composition:
Stoneware mugs: mainly made of materials such as kaolin, feldspar and quartz, which are fired at high temperatures to form a dense structure.
White porcelain mugs: usually made of kaolin and other minerals, fired at a higher temperature, with better transparency and luster.
Firing temperature:
Stoneware mugs: fired at temperatures usually above 1200°C, forming a high strength and low water absorption.
White porcelain mugs: firing temperatures are usually around 1300°C, resulting in higher densities and lower water absorption.
Appearance and texture:
Stoneware mugs: smooth surface, fine texture, usually with a high gloss, but relatively few colour and pattern options.
WHITE PORCELAIN MUGS: White in appearance and glossy, usually with better clarity for a wide range of decorations and patterns.
Durability:
Stoneware mugs: last longer and are less likely to break due to their high strength and abrasion resistance.
White porcelain mugs: relatively brittle, although they also have a certain degree of durability, they are easy to break when dropped or bumped.
Thermal insulation performance:
Stoneware mugs: due to its dense nature, better thermal insulation performance, suitable for hot drinks.
White porcelain mugs: relatively poor insulation performance, suitable for cold drinks or hot drinks consumed within a short period of time.
Price:
Stoneware mugs: usually more expensive due to the complexity of the production process.
White porcelain mugs: wider price range, usually more affordable.
Material properties:
Stoneware mugs usually have good heat resistance and can withstand microwave heating due to their high temperature firing properties.
Decorations and coatings:
Stoneware mugs with metal decorations or special coatings may not be suitable for use in the microwave as the metal can create sparks in the microwave, which could lead to damage or safety hazards.
Temperature Changes:
Avoid placing stoneware mugs directly from the refrigerator into the microwave when heating in the microwave to prevent the mugs from breaking due to sudden temperature changes.
Heat resistance:
Stoneware mugs usually have good heat resistance due to their high-temperature firing properties and can withstand dishwasher cleaning at high temperatures.
Patterns and Decorations:
If stoneware mugs have metal decorations or special coatings on them, they may not be suitable for dishwasher cleaning as the high temperatures and strong water streams may damage these decorations.
Placement:
When placing in the dishwasher, make sure the mugs are stable and avoid bumping against other crockery to prevent breakage.
Detergent Selection:
Use a mild dishwasher detergent and avoid detergents containing bleach or strong acids to protect the surface of the mugs.
Customising your own stoneware mug can usually be done in the following steps:
Choose a design:
Determine the pattern, text or colour you want. You can use your own design or choose a ready-made template.
Choose the mug shape:
Choose the shape and size of the mug according to your personal preference. Common ones are mugs, teacups, etc.
Find a supplier:
Search online for manufacturers or platforms for customised ceramic mugs, such as Taobao, Jingdong, or specialised customisation websites.
Submit design:
Upload your design file to the supplier's website, make sure the file format meets the requirements (e.g. PNG, JPEG, etc.).
Confirm samples:
Some suppliers will provide sample confirmation service, you can check the sample effect first to make sure you are satisfied with it before proceeding to mass production.
Place order for production:
After confirming the design and samples, place the order and pay for it.
Wait for delivery:
Generally customised products need a certain amount of production time, just wait patiently for delivery.
Attention.
Ensure the copyright of the design, avoid using unauthorised patterns.
Know the production time and shipping cost so as not to affect the time of use.
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.
