|
|
A plastic kaolin from South Carolina which is considered a course particle sized kaolin and used primarily for white stoneware bodies. Has very good throwing properties but does not lend itself to translucency.
|
|
|
|
|
|
|
|
|
From New Zealand China Clays, for use in highest quality tableware where exceptional whiteness and translucency are demanded. Extremely low Fe 2O 3 & TiO 2
