SW-252 Blue Opal

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.

Mayco’s Stoneware Glazes are Food Safe, Non Toxic and Non Hazardous when used according to manufacturer's directions.

Glaze is fired to cone 6 in the first image, and cone 10 in the second.

Cone 6: Blue Opal is a medium blue semi-transparent to fully opaque gloss glaze. Thinner applications create a transparent blue haze; thicker coatings produce an
opaque finish. Surface textures can cause the glaze to collect and produce streaks of greyish blue.

Cone 10: Becomes more transparent. Can produce red mottling in a heavy reduction.

TIP: Light applications on brown and buff bodies will produce a transparent green-blue gloss finish. Thinner application will provide a glossy transparent finish. Thicker application will provide light blue floating. Surface decoration will be visible under the glaze, but if you apply the glaze thick, it could blur your image.
