Notes

A popular medium plasticity buff burning clay used in stoneware, sculpture and many other types of clay bodies. It is very refractory (8-10% absorption, 12% total shrinkage cone 10) and fires to an attractive surface. It is considered very consistent.

It is also used for mortar for building kilns.

Typecodes	Clay Other Clays that are not kaolins, ball clays or bentonites. For example, stoneware clays are mixtures of all of the above plus quartz, feldspar, mica and other minerals. There are also many clays that have high plasticity like bentonite but are much different mineralogically.
Typecodes	Fireclay Fireclays are non-kaolin non-ball clay materials similar to stoneware clays but lacking fluxing oxides. Many fireclays have a PCE of 28 or more.
