Product Overview
Temperature Firing range is from Cone 05 (1915° F.) to Cone 03 (2014° F.) Recommended firing temperature is Cone 05 (1915° F.). Tip Although Amaco Opalescent Glazes may be used on any Amaco clay, they develop their greatest opales cence and most interesting textures when applied over red burning Amaco Indian Red Clay No. 67. Most of the Amaco Opalescent Glazes have a high gloss with anirides cence 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 can be used very effectively in Raku firing. We suggest controlled experimentation with Opalescent Glazes (for example O-42, O-23 at Cone 5, 2185°F.) When fired at this temperature on the inside of a stoneware bowl, the glaze flows to produce a variegated bottom and thins at the rim to expose more of the clay body. Amaco Opalescent Glazes are supplied in liquid, ready-to-use form. They are applied on bisque or greenware by brushing, dipping or pouring. On red bisque these glazes should be applied rather heavily, and a slow rather than fast firing is best Safety To download a copy of the AP (Non-Toxic) colors MSDS sheet in PDF format, please click here.
