Cone 6: 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: 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.
