Clay crafts are containers or crafts made from clay or pottery after firing.
Clay is a soil with little sand and sticky soil. It is not easy for water to pass through to have good plasticity.
Generally, clay is formed by weathering silicate minerals on the earth’s surface. Generally, it is weathered in situ, with larger particles and components close to the original stones. It is called primary clay or primary clay. The composition of this clay is mainly silica and alumina, which are white and refractory, and are the main raw materials for the preparation of porcelain clay.
