I had intended to post all the items from my Spring Raku pottery course, but realize that I had not gotten to the obvara items. The obvara raku, which involves dipping the hot pottery into a fermenting yeast mixture, then into cold water (see this post for more photos of the obvara raku process), was the technique I was least interested to try. I'm not sure I like the effect, but I'm glad for the experience.
I had seen some videos online of someone who used the obvara method to finish some sodium silicate crackled pots, and the result was pretty interesting. So I decided to do the same. Perhaps it was our obvara recipe, or other factors, but the obvara finishing didn't accentuate the sodium silicate texture, it seemed to make its own visual texture. Oh well, still interesting, I guess.
