Gray Opal SW255 Stoneware Classic, Cone 6-10

Consistent Performance and Control!

Cone 6 oxidation (first photo): Gray Opal creates a transparent gloss finish. It deepens in color from one coat to three but surface decoration and design remain visible through the glaze even with three coats. The glaze will break and pool around surface textures, creating opportunities for the opalescent character to develop.

Cone 10 reduction (second photo): Color lightens; becomes more transparent.

TIP: Thinner application will provide a glossy transparent finish. Thicker application will provide blue white floating. Surface decoration will be visible under the glaze, but if you apply the glaze thick, it could blur your image.
