Mayco Fundamentals Underglazes are highly versatile - use for complete coverage or to create design elements. They can be applied to wet clay, green ware or bisque. If your piece has texture, dab excess color out of the texture, and avoid allowing glaze to pool inside textures. Underglazes are formulated to mature at Cone 06/05; however, most maintain their color at higher temperatures. For best results, test on your clay body and in your kiln prior to use on finished pieces.
