[0002] Daily tableware is mainly made of ceramics, mainly including reinforced porcelain, high white porcelain, bone china, beautiful quality porcelain and other ceramic products. Although these ceramic products have good strengthening performance, impact resistance and high temperature resistance, their disadvantage is the firing temperature. High, high energy consumption, heavy weight, general freshness preservation and health care performance, and the product cannot be weathered and degraded after being fired at high temperature, and it is easy to cause environmental pollution when discarded after use, especially the waste and defective products generated in the production process form ceramic waste, which is even more Pollution and harm to the ecological environment
Although the terracotta products produced with laterite porcelain clay have light weight, low firing temperature, low energy consumption, and easy weathering after product damage, they are only used in tea sets and handicrafts because of their brittle texture. Applied to daily tableware, the application field is limited
