Mayco’s line of Stoneware Glazes are available in a beautiful array of colors, tints and tones. They were developed to perform from mid-range (cone 4/6) to higher fire (cone 9/10) temperatures. These glazes work well on both stoneware and porcelain and are designed so that they do not run. Most of Mayco’s Stoneware Glazes are available in pre-mixed pints, as well as a dry mix.

Mayco’s Stoneware Glazes should be applied to bisqued ceramic pieces. If dipping, one coat of glaze is sufficient. Use 2-3 coats if brushing or spraying, allowing glaze to thoroughly dry in between each layer of application. The glazes can be fired from cone 4/6 to cone 9/10 in oxidation or reduction atmospheres. If using dry mixes, no sieving is necessary but it is recommended that the dry materials be mixed before adding water, in case some of the materials have settled in the bag. The ratio of water added to dry mix is approximately 1 pint of water (16 oz.) to 1 pound of dry glaze. Premixed glazes should be stirred well before being applied to pots or other ceramic wares.

The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired results. We recommend that glazes always be tested on your clay body.

Cone 6 results: Green Jasper is a glossy, transparent white glaze that breaks over texture. Contains metallic green and blue crystals. Base color is stable, crystals can create movement.

Cone 10 reduction: Base remains. Crystals shift to metallic red. Light application recommended.

Tip: Green Jasper uses SW250 White Opal as the base glaze. Upon opening, crystals will be concentrated in the bottom of the bottle. Stir/shake thoroughly to incorporate before each use. Crystals can create movement. Avoid having a heavy
concentration of crystals near the bottom of your piece. When storing a crystal glaze, you may consider storing upside down to make crystal more accessible."
