White Opal - Dry
Description
Stoneware glaze for dipping. Fires between 1200 °C and 1260 °C (cone 5 to 10). Can be sprayed and used for oxidation, reduction, among others. Since clays can vary and have different properties, we recommend testing the glaze on a small piece of the clay you intend to use. The bag contains powder to be mixed with water according to the instructions.
Stoneware classic glazes offer the depth, sophistication, and reliability to artists working from mid-range to high-fire temperatures. Many glazes will break over textures, revealing secondary colors and shades. Used alone, stoneware glazes produce beautiful color variations. One coat will allow the clay body to show through the glaze and two to three coats deepen the color. The choice of clay body, thickness of glaze application, firing process, and temperature will affect the fired finish.

Information
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.
Safety
Can be irritating, harmful to health, and environmentally hazardous.
