The Obvara technique, 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 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.
In today’s post, an excerpt from her video Raku Firing: Expanding the Potential of the Raku Kiln, Marcia Selsor shows how to enhance the effects of an Obvara firing by texturing the surface and then shows the exciting process.- Jennifer Harnetty, editor.
