Using horsehair and feathers in raku firing yields incredible marks that can’t be created in any other type of firing. But for optimal results in horsehair and feather raku, you should have a smooth surface. Marcia Selsor creates this ideal surface with terra sigillata and I loved her no-muss-no-fuss method for mixing sig. In today’s video, an excerpt from her brand new video Raku Firing: Expanding the Potential of the Raku Kiln, Marcia demonstrates this technique and a horsehair/feather firing.- Jennifer Harnetty, editor.
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.

Marcia Selsor uses a surface, prepares it to react in a certain way, or reheats and erases it, to create infinite possibilities of surface decoration. She also uses flashing, fuming, smoking, and post firing chemical effects — all of which the following methods will be used at the Alternative Firing Surfaces Conference.
