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.
Historically, reaching high temperatures was a long-lasting challenge, and earthenware can be fired effectively as low as 600 °C (1,112 °F), achievable in primitive pit firing. The time spent at any particular temperature is also important, the combination of heat and time is known as heatwork .
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 ...
Earthenware comprises "most building bricks, nearly all European pottery up to the seventeenth century, most of the wares of Egypt, Persia and the near East; Greek, Roman and Mediterranean, and some of the Chinese; and the fine earthenware which forms the greater part of our tableware today" ("today" being 1962).

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 ...
Fire clay in a furnace. Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick. The United States Environmental Protection Agency defines fire clay very generally as a "mineral aggregate composed of hydrous silicates of aluminium (Al 2 O 3 ·2SiO 2 ·2H 2 O) with or without free silica."
