Speedball - Underglazes

Speedball's underglazes are highly concentrated underglazes that can be used directly as printing ink for various printing techniques due to their thick consistency (which can sometimes feel grainy). They can be brushed on as is, requiring no more than one or two coats, or mixed with water or resin to achieve the consistency of other underglazes. It can be applied to clay, leather, or fabric using a brush, sponge, or palette knife. Colors can be mixed together or combined with other glazes.
