Introduction of traditional ceramics

Ceramics is a general term for pottery and porcelain. China people invented pottery as early as about 8000-2000 BC (Neolithic Age). Ceramic materials are mainly oxides, nitrides, borides and carbides. Common ceramic materials are clay, alumina, kaolin and so on. Ceramic materials generally have high hardness, but poor plasticity. Besides the use of utensils and decorations, it also plays an important role in the development of science and technology. Ceramic raw materials are the earth's original resources, clay, which is quenched. Clay is tough, plastic when it meets water at room temperature, slightly dry and grindable; Fired to 700 degrees, pottery can hold water; It will be porcelain when it is burned to 1230 degrees, and it will not absorb water at all, and it is resistant to high temperature and corrosion. In today's culture and technology, its flexibility of use still has various creative applications.
