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.
PLEASE NOTE* This is a new product and not 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.
