Most of the AMACO® Opalescent Glazes have a high gloss with an
iridescence similar to mother-of-pearl. Best results are achieved with
three or four applications of glaze. On textured ware, these iridescent glazes flow 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 (2205°F, 1207°C). 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
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.
Firing range is from Cone 05 (1911°F, 1044°C;) to Cone 03 (2019°F,
1104°C). The recommended firing temperature for these iridescent glazes is Cone 05 (1911°F, 1044°C).
