Cone 6 oxidation (first image): Robin’s Egg is a greenish-blue matte glaze that contains a sand-colored crystal. As the crystal melts, a small sandy-brown bloom will appear in the glaze, producing a mottled, textured finish.

Cone 10 reduction (second image): Semi-gloss finish with variegated blue/light blue and crystals.

TIP: SW-105 Frost Blue is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-105 Frost Blue with a third coat of SW-116 Robin’s Egg.

One of the most distinctive traits of Mayco’s Stoneware is that the glazes provide consistent performance and intriguing visual interest. They are best known for being receptive and favourable to the user during both application and firing. Mayco Stoneware glazes are friendly to the user in application, layering and firing. Many glazes will break over textures, revealing secondary colours and shades. The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired results.

Stoneware Classic & Matte Glazes: Stir well. Apply to soft-fired bisque (cone 04/06). Apply one, two or three coats depending on the result desired. Allow each coat to dry before applying the next coat. Fire from cone 5/6-10. See label for additional firing information for individual glazes and cone 10 performance.

Stoneware Crystal Glazes: Crystal glazes are designed to expand upon the surface with dazzling bursts of color. Crystals will settle to the bottom of the jar and will need thorough mixing prior to initial use and in between each coat. Apply two to three coats using a fan or hake brush. While the glaze is wet, use your brush to redistribute crystals to achieve balanced coverage. Over application of the crystals can cause pinholing or running. Avoid placing crystals near the bottom third of a vertical piece as they may cause additional movement during firing. See label for additional firing information for individual glazes and cone 10 performance.

Stoneware Gloss Glazes: Stoneware Gloss glazes can be used in design, all over coverage and are the ideal product for intermixability at mid-range temperatures. The integrity of your design will remain unchanged as these glazes are incredibly stable and will not move or combine with surrounding colors. See label for additional firing information for individual glazes and cone 10 performance.
