Grolleg is a blended English kaolin typically used for making translucent porcelain clay bodies. The material has a low shrinkage rate and fires to a blue/white color. It has moderate plasticity and a low titania and high flux content.
A glaze or clay body will almost always specify Grolleg if Grolleg is necessary. If it just says china clay or kaolin, other kaolins are a more cost-effective option.
