High Fire Underglazes

Coyote Underglazes are the only commercially available underglazes specially designed to be fired at cone 5-6.  The colors can be mixed, and stay true and stable up to cone 10 in oxidation.  They are always bold and striking, and are suited to functional ware when covered in Coyote Gloss Clear and fired to cone 6. They can be used on either greenware or bisque.

Intense pigment and high definition are the trademark of Duncan® E-Z Stroke® Translucent Underglazes. These versatile underglazes are perfect for brushwork, airbrushing and antiquing, helping you achieve the look of watercolor or detailed shading on greenware or bisque. Firing range cone 06 to cone 6.

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.
