The high-temperature resistant design of ceramic hot pot bowls

The high-temperature resistance design of ceramic hot pot bowls is mainly reflected in aspects such as material, craftsmanship and structure. Here is a detailed introduction for you:

Material selection

Special formula ceramics: Some ceramic hot pot bowls are made with special formulas and techniques. High-temperature ceramics represented by Jingdezhen ceramics can withstand temperatures above 1000℃. They not only meet the needs of home baking but also can cope with the high-temperature environment of hot pot. This type of ceramic material, when combined with materials of a lower coefficient of thermal expansion, can prevent cracking in high-temperature cooking environments.

Reinforced materials: For instance, magnesium-reinforced porcelain, due to its material properties, has relatively loose requirements for thermal shock resistance. The minimum requirement is that it should not crack after one heat exchange at 140℃ to 20℃. It can adapt to certain changes in cold and hot environments and is suitable for use as a material for hot pot bowls.

Firing process

High-temperature firing: After multiple high-temperature firing processes, ceramic hot pot bowls have extremely high durability and can easily handle high-temperature ingredients. For instance, there are ceramic hot pot bowls that have been fired at a temperature of over 1.380 degrees Celsius, capable of withstanding significant temperature variations. Even when cold or hot, they will not crack.

Underglaze painting technique: Ceramic hot pot bowls designed with the underglaze painting technique not only feature beautiful patterns that are not prone to fading or falling off, but also this technique helps enhance the overall performance of the bowls, ensuring their stability even at high temperatures. The protective layer formed by the underglaze painting process can enhance the bowl's high-temperature resistance and corrosion resistance.

Structural design

Anti-scald design: Some ceramic hot pot bowls adopt anti-scald design, such as having double ears or high legs, which are convenient to take and prevent hands from being burned during use. For instance, the blue and white porcelain anti-scalding soup bowl features a double-ear design that enables users to safely hold the bowl containing hot soup or hot pot ingredients.

Thickened design: The specially thickened ceramic hot pot bowl is more suitable for use in high-temperature environments, such as heating ingredients in ovens and microwave ovens. The thickened bowl wall can better withstand high temperatures and reduce the risk of cracking caused by temperature changes.
