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).

Earthenware jar from the Neolithic Majiayao culture China, 3300 to 2000 BCE. The earliest forms of pottery were made from clays that were fired at low temperatures, initially in pit-fires or in open bonfires. They were hand formed and undecorated. Earthenware can be fired as low as 600 °C, and is normally fired below 1200 °C. [9]
The porous nature of (fired) biscuit earthenware means that it readily absorbs water, while vitreous wares such as porcelain, bone china and most stoneware are non-porous even without glazing. [6] The temperature of biscuit firing is today usually at least 1000°C, although higher temperatures are common. [ 7 ]
[40] [41] [42] The small, black to brown earthenware vessel is a cookware-cum-serveware used for various jjigae (stew), gukbap (soup with rice), or other boiled dishes in Korean cuisine. As a ttukbaegi retains heat and does not cool off as soon as removed from the stove, stews and soups in ttukbaegi usually arrive at the table at a bubbling ...
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 ...
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 types of ceramics can be divided into five groups: unglazed earthenware; glazed earthenware (施和的器 seyūtōki or 低火度前 teikadoyū): fired at relatively low temperatures 800–900°C using lead as the medium, the technique was introduced from the Korean peninsula in the 7th century.
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 ...
