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 this post, Marcia Selsor shows how to enhance the effects of an Obvara firing by texturing the surface and then shows the exciting process.- Jennifer Poellot Harnetty, editor.
