Coyote Copper Reds: Oxblood and Snowy Plum

Thickness tests showing one, two, three, and four brushed coats: Oxblood on the left, Snowy Plum on the right. Both colors are dramatically affected by the thickness of application.

True copper reds are among the most sought after glazes.  Because of the difference in firing processes between reduction and oxidation, producing a red copper glaze in an electric kiln is unusually difficult.  In order to extract these reds from our copper glazes, we include an agent that removes oxygen from the copper oxide in the glaze.  This creates a localized reduction environment that affects the piece with the glaze on it. If the glaze is applied too thinly, the copper will not reduce, producing a mostly clear glaze, sometimes streaked with crimson.  Thicker applications tend to yield better results, though the clay body may also have an effect.
