Modern earthenware may be biscuit (or "bisque") [13] [14] fired to temperatures between 1,000 and 1,150 °C (1,830 and 2,100 °F) and glost-fired [15] (or "glaze-fired") [4] [16] to between 950 and 1,050 °C (1,740 and 1,920 °F). Some studio potters follow the reverse practice, with a low-temperature biscuit firing and a high-temperature glost ...
Pottery is the process and the products of forming vessels and other objects with clay and other raw materials, which are fired at high temperatures to give them a hard and durable form. The place where such wares are made by a potter is also called a pottery (plural potteries ).
The ceramic part of the stove is made with clay, which is shaped and then fired. The qualities for the ideal type of clay for use are: ability to maintain good strength when fired at 900 °C; ability to remain slightly porous when temperatures reach 1150 °C; the clay should not warp or change shape when fired at 1250 °C.

The Punjabi tandoor from South Asia is traditionally made of clay and is a bell-shaped oven, which can either be set into the earth or rest above the ground and is fired with wood or charcoal, reaching temperatures of about 480 °C (900 °F; 750 K). [4] Tandoor cooking is a traditional aspect of Punjabi cuisine in undivided Punjab. [5]
[citation needed] The central Asian tandoor use the method primarily for uncovered, live-fire baking, which is a transitional design between the earth oven and the horizontal-plan masonry oven. This method is essentially a permanent earth oven made out of clay or firebrick with a constantly burning, very hot fire in the bottom.
Fire pots were vital to the development of civilization. Once humans had learned to contain, control and sustain fires, they had an invaluable tool for cooking food that would have otherwise not been edible. Fire pots were also useful for sharpening spears, hollowing out canoes, baking pottery, and many other tasks, such as staying warm.

Ceramics require high temperatures so chemical and physical reactions will occur to 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 and the temperature at which it is fired.
