Glass-Ceramic Glazes

Glass-ceramic frits are made by the controlled devitrification (crystallization) of a composition to create a homogeneous structure in a glassy matrix. Glaze employing these crystalline frits have improved hardness. Glass ceramic coatings are common on tiles because of their superior abrasion resistance compared to glazes. These materials can be lead free and thus offer a way to produce very bright colors without using encapsulated stains (utilitarian ware employing frit glass in the glaze is often very brightly colored).
