Although AMACO® Opalescent Glazes may be used on any clay body, they develop their greatest opalescence and most interesting textures when applied over red burning clay bodies. Most of the AMACO® Opalescent Glazes have a high gloss similar to mother-of-pearl.
Best results are achieved with three or four applications of glaze. On textured ware, the glaze flows thin on relief and thick in incised areas, giving an added dimension on the surface.
AMACO® Opalescent Glazes are supplied in liquid, ready-to-use form in pint jars. They are applied on a mature Cone 04 (1971°F, 1077°C) bisque by brushing, dipping, or pouring. On red bisque, these glazes should be applied rather heavily, and a slow rather than fast firing is best. Recommended temperature is Cone 05 (1911°F, 1044°C).
