Andrew Kellner is off to graduate school in Sept so he gave the old bull his supply of a bastardized porcelain clay body. Well actually it is 3 different particle sizes of silica sand, some feldspar(another non plastic and a titch of kaolin added to make it throwable. This is a clay for those that love to throw a slightly stiff mortar mix. So I'll come clean. I love this clay and especially trimming it. I have never liked using porcelain and I'm so glad Andrew made it dirty. They are destined to be pink shino or if my tests of Georgia orange come out then we'll have some peach as well.
