Cornish Stone is no longer available therefore after some research we have found this substitute product. Cornish Stone was decomposed granite. Used as a secondary flux in glazes at earthenware temperatures and as an alternative to feldspar at stoneware temperatures. Not as fusible as feldspar due to higher silica content. Our Stone Substitute is a milled material compiste flux designed to match the firing characteristics of Cornish Stone.
