Speedball Ceramic Underglazes feature bright and intense colors that are highly saturated for spectacular results. Compatible with Speedball Earthenware Glazes, they can be used for a variety of decorating techniques. They can be applied to both greenware and bisque and can be blended. Originally designed to perform in a wide firing range (Cone 06-6), they can be successfully fired at Cone 10.
The liquid, opaque colors will not move or bleed, making them perfect for detailed painting, design work, and sgraffito. Because they're lead-free and clean up easily with water, Speedball Earthenware Glazes are ideal for classroom use.
These underglazes are dinnerware safe when used and fired as directed. However, tableware producers should have finished ware lab tested to determine dinnerware suitability due to firing variances and contamination.
