Product Description

This Cornish Stone substitute 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. Nearly free from Iron, it is very white and opaque.

Due to a 50% rise in the cost of already expensive Cornwall Stone Substitute aka MFW30/G Spray Dried Flux, the decision was made to replace it with this affordable material. Laguna decided to market the substitute blend being used to replace Cornwall Stone in Laguna glaze production since Cornwall had become unavailable. In all Laguna's tests, at all temperatures, they found it worked the same at 1/3 the cost (of what was quoted to Laguna Clay as the new cost of the MFW30/G Spray Dried Flux).

The product is sold as SG919 Laguna Cornwall Sub.

The Typical Analysis comparisons below illustrate that there are only small variations in chemical composition, which show SG919 Laguna Cornwall Sub as a more chemically similar substitute for the natural Cornwall Stone.
