A specialized glaze, Oxblood contains a chemical that causes it to reduce locally, producing a true copper red in your electric kiln without a special firing. Because of the way this glaze works, it needs to be very thick to produce the red color. Thinner spots will be clear or grayish.
Cone 6 glaze.
Available in 5lb. bags of dry glaze. Consult Coyote’s website for specific mixing instructions for your glaze.
