Gray Opal
Description
Mayco’s stoneware glazes are preferably applied with a soft fan brush onto the bisque-fired ware. Fire between cone 5 and cone 6 (1200°C - 1230°C). Many colors also perform very well at higher temperatures — see images; test before applying on production pieces. 473 ml. Ready to use.
Information
Cone 6 oxidation (1230°C): Gray Opal creates a transparent gloss finish. It deepens in color from one coat to three but surface decoration and design remain visible through theglaze even with three coats. The glaze will break and pool around surface textures, creating opportunities for the opalescent character to develop.
Cone 10 reduction (1280°C): 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.
Safety
