These mugs are fired at cone 03. The outside glazes are G2931K transparent with added stain plus 3% Zircopax. The left one contains 10% Mason 6021 red. The right one has 15% Cerdec 297497 red stain. The latter is an older product, obviously not as potent. Encapsulated stains are a revolution in ceramics but test the ones available. You could save money and get better color at the same time.
G2931K - Low Fire Fritted Zero3 Transparent Glaze
A cone 03-02 clear medium-expansio glaze developed from Worthington Clear.
This is a type of stain manufacture that enables the use of metal oxides (like cadmium) under temperature conditions in which they would normally fail.
Mason 6021 Red Stain
An encapsulated red stain, it has proven better than any other red we have ever tried for glazes. And it works in bodies.
