Sometimes called English Cornish Stone, this is a calcium feldspar mineral used as a major constituent of glazes, and occasionally as a flux in bodies.  Cornwall Stone is partially kaolinized, and can contain between 5-12% kaolin.

*NOTE: This is a new product and not the one from the original mine, as that one was closed.  It looks pink due to the addition of Phosphorus Pentoxide (P2O5).  The product will fire white.  As always, we strongly recommend testing with any recipe to make sure it is compatible.

Comes in 55-pound bags. The price listed is the maximum per pound cost. We reserve the right to change pricing without notice due to the current market conditions. See table below for full-bag and quantity discounts.
