Clay is moulded into pots and heated at high temperature in a kiln. The final hardened material produced is classified as :
Ceramic
Clay is an inorganic, non-metallic raw material made mainly of silicate minerals. When it is shaped into pots and then fired at a high temperature in a kiln, the heat causes the particles to fuse and harden permanently into a rigid, heat-resistant, non-metallic solid.
This process of hardening an inorganic, non-metallic material by high-temperature firing is exactly how ceramics are made, which is why pottery, bricks, and tiles all fall under this category.
Therefore, the final hardened material is classified as ceramic.
