CAC MIDRANGE CLAY – PLUM BLACK (25# BAG)

Black/brown stoneware body with a fine/smooth texture.

For best results we recommend a fully oxidized (user your vent or remove all peeps) slow bisque fire to Cone 04 to fully burn out organics and a slow glaze firing that does not exceed Cone 5 or bloating may occur. Please use witness cones in your firings to confirm Cone. Manganese off gasses during firing so ensure your firing space is properly ventilated.
