The Obvara Firing Process

About the Process

The Obvara firing process, which originated in Eastern Europe around the 12th Century, involves scalding the finish on the pottery to seal the porous surface. Similar to the raku pottery process, a bisqued pot is heated, in this case to 1650°F (899°C) and removed from the heat. The difference is that the pot is then dipped into a specific obvara yeast mixture before being dunked in water to rapidly cool the piece. The effects are quite stunning.
