Cone 6 oxidation: Passionflower Purple is a glossy, opaque, deep purple glaze with opaque crystals in varying sizes that bloom into shades of blue, green, and yellow.

Cone 10 reduction: Glaze shifts to a semi-opaque variegated blue that breaks over texture. Crystals soften and lighten. Glaze remains stable.

TIP: SW-134 Eggplant is the base glaze. For a lighter crystal effect, apply 1 coat of SW-190 Passionflower Purple over 2 coats of SW-134 Eggplant. This glaze is stable, even with heavy application.

Stoneware crystal glazes are designed to expand upon the surface with dazzling burts of colour. Fired results will vary based on ware’s orientation. Crystals will settle to the bottom of the jar and will need a good mixing prior to initial use. Re-stir between each coat. Stir with palette knife or other unpainted tool. Avoid placing crystals near the bottom third of a vertical piece as they may cause additional movement during firing. Crystals will flow more than the base glaze. While the glaze is wet, use your fan brush to redistribute the crystals to achieve balanced coverage. Over-application or heavy deposition of the crystals can cause pinholing or running. When storing a crystal glaze, you may consider storing upside down to facilitate crystal dispersion on the next use.
