Ceramics
 
 
 
Ceramics are made of non-metallic minerals that have been permanently hardened by firing at a high temperature. Most ceramics resist heat and chemicals and are poor conductors of heat and electricity. Traditional ceramics are made of clay and other natural occurring materials, while modern high-tech ceramics use silicon carbide, alumina, and other specially purified or synthetic raw materials. Ceramic materials are used in all forms of pottery.
