Ceramics is a general term for pottery and porcelain. The Chinese invented pottery as early as about 8000-2000 BC (the Neolithic Age). Ceramic materials are mostly oxides, nitrides, borides, and carbides. Common ceramic materials include clay, alumina, kaolin, etc. Ceramic materials generally have high hardness but poor plasticity. In addition to its use in tableware and decoration, it also plays an important role in the development of science and technology. Ceramic raw materials are obtained by quenching a large amount of clay, a natural resource on Earth. And the properties of clay are tough, plastic when exposed to water at room temperature, can be carved when slightly dry, and can be ground when completely dry; Burning to 700 degrees can make pottery that can hold water; When burned to 1230 degrees, it will undergo porcelain transformation, completely non absorbent, and resistant to high temperatures and corrosion. The flexibility of its usage still has various creative applications in today's cultural and technological fields.
