A buff firing, medium plasticity, slightly toothed fireclay. Ideally suited as a refractory agent to reduce body maturity, yet not adversely affect its working and drying properties, or overly darken its fired color.

This material is good substitute for the popular but discontinued AP Green Missouri Fireclay. It fires to a similar color and is a bit more refractory.

Fireclays are often inexpensive and thus coarsely (or even erratically ground). They are implicated in lime-popping. Fireclay should be ground to at least 30 mesh to eliminate this problem.
