Problems solved by technology

[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

Embodiment

[0016] Embodiment: a kind of preparation method of underglaze terracotta tableware comprises the following steps:

[0017] (1) material selection: adopt ore soil or compound as raw material, by weight percentage: purple clay 40%, red clay 30%, white clay 30%;

[0018] (2) Making red pottery clay: mixing the proportional red pottery soil ore and adding appropriate amount of water through ball milling and stirring for 12 hours, crossing a 200-mesh mud mesh sieve, pressing and drying to form red pottery mud;

[0019] (3) Roll forming is used to make the terracotta tableware body;

[0020] (4) Biscuit firing: firing the terracotta tableware body under an oxidizing atmosphere at a firing temperature of 980° C. and a firing time of 8 hours. After the end point temperature, stop the fire, keep warm for 7.5 hours to cool naturally, and leave the kiln;

[0021] (5) Ceramic white glaze and decal paper;

[0022] (6) Bake and dry in a kiln, the drying temperature is 750°C, the time is 4...
