Generally, the ceramics we use are called daily-use ceramics, such as tableware, tea set, coffee set, wine set, rice set and so on.
One of the important indexes of daily-use ceramics is thermal shock resistance. Thermal shock resistance is a characteristic index that shows the ability of ceramic products to resist sudden changes in external temperature without cracking or damage, and it is an important performance index. Most ceramic products for daily use are in contact with heated food. Products with poor thermal shock resistance will crack or break under the action of thermal shock, and the strength of the products is low, which may break when holding food, causing harm to human body.
