Formulated as a substitute for UK Cornwall Stone for use in North America.

This was described in an article in Ceramics Technical Nov 2011. The chemistry has some significant differences to the standard UK Cornwall Stone (e.g. 5% more SiO2, 0.4% CaO vs. 1.8%, 6.9% KNaO vs. 7.6%). These suggest that it will not melt as quite as well, testing should be done.
