Cover-Coat® Opaque Underglazes are formulated for both greenware and bisque and provide opaque color coverage, even when applied over another color. These clay, water-based underglazes fire to a porous matte finish; apply a clear glaze for shiny color.
Low heat angobs (burning 995-1060 ° C)
Concepts® are underglaze colors designed primarily for decorating bisque. These colors are frit-based; therefore, when three coats are applied, they have a glossy sheen when fired. One, two, or three coats may be applied.
Low heat angobs (burning 995-1060 ° C)
