Bisque (pottery)

From Wikipedia, the free encyclopedia

Bisque porcelain is unglazed, white ceramic ware.[1][2] A popular use for bisque porcelain was the manufacture of bisque dolls in the 19th century.[3]

The related term, biscuit,[4][5][6][7][8][9] refers to pottery that has been fired but not yet glazed. The porous nature of biscuit earthenware means that it readily absorbs water, while vitreous ware and bone china are almost non-porous even without glazing.[10] The temperature of biscuit firing is usually at least 1000°C, although higher temperatures are common.[11] The firing of the ware that results in the biscuit article causes permanent chemical and physical changes to occur. These result in a much harder and more resilient article which can still be porous, and this can ease the application of glazes.
