Notes
A popular secondary clay used in both clay and glazes. This ball clay is the base for a number of very popular premixed plastic porcelain and whiteware bodies in USA. It is very plastic, fires to a light grey color with about 13% shrinkage at cone 10. Many potters claim that this is the whitest firing ball clay available in North America. In the powder form it looks much more like a light beige kaolin than a grey ball clay.
