Ceramic Tunnel Kiln

Kilns are an essential part of the manufacture of all ceramics, which require heat treatment, often at high temperatures. During this process, chemical and physical reactions occur that permanently alter the unfired body. In the case of pottery, clay materials are shaped, dried and then fired in a kiln. The final characteristics are determined by the composition and preparation of the clay body, by the temperature at which it is fired, and by the glazes that may be used. Although modern kilns often have sophisticated electrical systems to control the firing temperatures, pyrometric devices are also frequently used.
