Specific gravity: 1.43. The surface of this glaze lives up to its name as a smooth and stony matte. The color response is not as vivid as it would perhaps be without the added magnesium carbonate. With cobalt carbonate, it is in the lilac range and with copper carbonate, it is a pale green. This glaze is not food safe. For color variations, omit the zinc oxide.
