Glaze is a glassy melted coating that is fired onto ceramic pieces. Once fired, glazes may be glossy, satin, or matte. If you’re creating clay surfaces intended to hold food, a gloss glaze is an excellent option because it makes it easier to clean the dish. A matte glaze will be non-reflective and can be smooth or stony to the touch. Satin glazes will have a low, waxy sheen that is smooth in texture.

Underglazes are commercial products made up of finely ground clays and frits with oxides and stains. Underglazes usually require a clear or transparent glaze on top of them to seal the surface. You can paint, pour, spray, or dip the underglazes on your creations. Usually, underglazes require three coats. However, Clay-King offers one-coat products that are often fluxed to produce a low sheen.
