Which material is a ceramic?

Explanation:
Ceramics are inorganic, non-metallic solids typically made from powders and hardened by firing to a high temperature. Clay fits this category because it is an earth mineral composed mainly of aluminosilicate; when heated in a kiln, the minerals bond and it loses moisture, becoming hard, rigid and heat resistant—a ceramic material. That contrasts with wood, which is organic and fibrous; steel, a metallic alloy; and rubber, a polymer. Hence, clay is the ceramic.
