Cone 6: Shipwreck is an aquamarine gloss glaze that contains an iron crystal. As the crystal melts, a small iron speck appears. The glaze appears mysterious like underwater footage.
Cone 10: Color darkens.
TIP: SW-212 Peacock is the base glaze.For a lighter crystal effect, you may try applying two coats of SW-212 Peacock with a third coat of SW-54 Shipwreck.
Stoneware crystal glazes are designed to expand upon the surface with dazzling bursts of color. 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.
