Mason 6001 Alpine Rose Stain Glazes. Low Fire-Mayco Calcined kaolin is valuable in

Calcined kaolin is valuable in glaze formulations that contain high amounts of kaolin to source alumina and which are thus subject to shrinkage and cracking-during-drying problems

This material is good substitute for the popular but discontinued AP Green Missouri Fireclay

This borosilicate frit is high in calcium which means it will affect browns and iron oxide colours

Mason 6001 Alpine Rose Stain Glazes. Low Fire-Mayco Calcined kaolin is valuable inStains are a mixture of ceramic oxides and coloring metal oxides that are melted in kilns, quenched, ground to specific mesh size (some are acid washed), and colored with organic dyes to simulate the fired color. Essentially they are fritted colorants. They are made and manufactured for several reasons: to provide a consistent and stable form of colorant that doesnt dissolve in the glaze melt as easily as coloring metal oxides; to make colorants safer
