Cone 6 oxidation (larger image): White Opal forms a clear- to- milky white gloss surface. One coat produces the clearest finish; subsequent layering increases the incidence of a white precipitate forming. Prominent white to bluish-white colors will emerge where the glaze pools and gathers around surface texture.

Cone 10 reduction (smaller image): White variation lessens leaving a transparent gloss with white pooling.

TIP: White coloration is more visible on darker clay bodies (Buff, Manganese Speck). Thinner application will provide a glossy transparent finish. Thicker application will provide white floating.
