Cone 6 oxidation (first image): Midnight Rain is a blue-green breaking gloss glaze that contains a black crystal. As the crystal melts and moves, a black oil-like streak is created in the glaze.

Cone 10 reduction (second image): Crystals melt and integrate into base glaze, darkening the color. Increased movement.

TIP: SW-100 Blue Surf is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-100 Blue Surf with a third coat of SW-115 Midnight Rain.

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.
