Made of porous clay fired at low heat.
Pottery made of porous clay and fired at relatively low temperatures of up to 1,200ş C/2,200ş F. It does not vitrify but remains porous, unless glazed. Earthenware may be unglazed (flowerpots, wine-coolers) or glazed (most tableware); the glaze and body characteristically form quite separate layers).
The most ancient pottery was fired earthenware (terracotta), which is known to date back to the Mesolithic period in N Europe and E Africa. Today, pots fired in the traditional method for local use in parts of South America, Indonesia, Africa, and the Indian subcontinent are sometimes burnished to a smooth finish, which strengthens them. They often have an attractively uneven distribution of shades due to different rates of oxidization in the low temperature of an open fire (about 600şC/1,000şF); kiln-fired pots (fired at 1,000–1,200şC/1,832–2,200şF) are more evenly colored and matt. + prikaži više

A strong opaque ceramic ware that is high-fired, well vitrified, and nonporous
Is high-fired, vitrified and nonporous.
Very hard, opaque, water-resistant pottery made of non-porous clay with feldspar and a high silica content, fired to the point of vitrification (1,200–1,280ş C/2,192–2,336ş f).
Glazing decorates and gives it a smooth finish; it usually fires to shades of gray or buff, though some red stonewares do exist. The earliest examples are Chinese, from the 10th to 3rd centuries bc.
From the 9th century ad stoneware was made in N Europe; in Britain from the late 17th century. + prikaži više
