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 ...
In Middle and South Europe, grog is used to create fire-resistant chamotte type bricks and mortar for construction of fireplaces, old-style and industrial furnaces, and as component of high temperature application sealants and adhesives. A typical example of domestic use is a pizza stone made from chamotte. Because the stone can absorb heat ...
In catering, the burner heats a water reservoir, making it a sort of portable steam table. [17] Historically, it was a kind of portable grate raised on a tripod heated with charcoal in a brazier. [18] The chafing dish could be used at table or provided with a cover for keeping food warm on a buffet.
An earthenware fire-pot or indigenous stove found in West Africa , [3] notably in Ilora and Oyo, an Adogan has a flat bottom with a carinated wall and an out-turned rim with three decorated lugs to support the cooking pot. A U-shaped hole is cut in one side to allow air to enter, and through which fuel is inserted.
The filled pit is then set on fire and carefully tended until most of the inner fuel has been consumed. At around 1,100 °C (2,010 °F) the maximum temperatures are moderate compared to other techniques used for pottery, [4] and the pottery produced counts as earthenware. After cooling, pots are removed and cleaned; there may be patterns and ...
In Jewish culture, especially on days where it was impossible to build a fire, but where prolonging the existing heat of the oven was necessary, the hot coals were, in advance, pushed to one side and covered over in ashes, while the entire clay oven was covered over with a larger earthenware vessel, to which old rags were added along the edges ...
It is used for cooking at table, notably in gueridon service, or as a food warmer for keeping dishes at a buffet warm. Historically, a chafing dish (from the French chauffer , "to make warm") is a kind of portable grate raised on a tripod, originally heated with charcoal in a brazier , [ 1 ] and used for foods that require gentle cooking, away ...
Refractory fire clays have a high concentration of kaolinite, with lesser amounts of mica and quartz. Non-refractory fire clays, however, have larger amounts of mica and feldspar. [15] A Staffordshire pottery stoneware plate from the 1850s with white glaze and transfer printed design. Visually this hardly differs from earthenware or porcelain ...
