Background info on processes:
The obvara firing process originated in Eastern Europe around the 12th Century and involves scalding the finish on the pottery to seal the porous surface. A bisqued pot is heated to 1650°F and then dipped into a specific obvara yeast mixture before being dunked in water to rapidly cool the piece. The effects are quite stunning.
Horsehair raku pots are similarly heated and then various combustible items (horsehair, feathers, sugar, etc.) are then laid on the surface where they will burn leaving black marks and gray smoke shading. Ferric chloride is also sprayed on the pieces to produce yellow-gold coloring.
