Obvara fired.
Obvara firing at Raku Rendezvous in Ardmore, Ok.
Obvara is an old eastern european technique involving scalding the finish on the pottery to seal the porous surface. The bisqued piece is heated to 1500 to 1650 F., removed from the kiln and dunked into the Obvara mixture and then dunked in water to rapidly cool the piece. The pieces range from tan to almost black with speckles. The mixture consists of approx 2 pounds flour, 2 packets of yeast about 1/4 cup of sugar and about 4 gallons of water.. It is mixed and allowed to ferment about 3 days before use. it smells like beer or sourdough to me. it fits well with the raku process most potters are familiar with. The obvara mixture provides the decoration as well as the reduction of the pot. it is almost smokeless, which can be a great advantage in a city or school situation.
