Stoneware
A high fired (about 1150C+) ceramic clay that is semi-vitreous (not translucent and not zero porosity). Industrial stonewares are typically refined and fire white or grey and are glazed with opaque and colored glazes. There is a fuzzy line between stoneware and whiteware (the latter has higher porosities and lower strengths because it is not fired to as high temperatures). Stonewares used by potters and traditional potteries generally employ less refined materials, they can fire brown, grey, buff or white. They also commonly have some speckle impurities and some particulate material such as sand or fine grog the impart a tactile surface. Stonewares are noted for their excellent working properties, stoneware throwing bodies, for example, are prized by potters (the clays used are ball clay based rather than kaolin based). The workability of these materials results from the fact that their recipe does not need to contain alot of feldspar or silica (these cut plasticity), the clay materials contain these naturally. These bodies generally cannot be fired to zero porosity without bloating. Out Bound Links
