Three footed cauldron. Glossy black inside, raw unfinished clay outside with a freehand brushed pentacle in matte black.
PSH cone 6 clay Black C540i
Pigmented with non-toxic iron oxide. Fires to a deep brown/black, deeper black when sealed with a transparent glaze. Not recommended for microwave heating because of its iron oxide content.
PSH Wax Resist Emulsion UWAX2
A brushable, water-wax emulsion applied to bisque pots to resist glaze. The wax burns away during firing, so none is present in the finished piece.
PSH Black Matte Glaze GBKM2
Non-toxic (lead free) matte black, suitable for the exterior of pots. Rigid and durable, but vulnerable to scratches, gives a dark matte surface that resembles cast iron. A slow-drying glaze for brushing and detailed decoration.
