Mason 6021 encapsulated stain in Plainsman M370 transparent fired at cone 6 on M370 (with second layer of two other colors). Notice the bubbling. This stain is rated to 2300F, it appears that even cone 6 is pushing its limits.
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.
