Fire, smoke, feathers… and a bucket of fermented yeast? Welcome to our Raku workshop. 🔥
Unlike our usual firings, where pottery cools inside the kiln, these processes involve removing pieces while they’re still incredibly hot—and letting what happens next shape the finish.
Here are three techniques we explored:
🔥 GLAZED RAKU + REDUCTION
Glazed pieces are lifted from the kiln with tongs and placed into a metal reduction bucket containing combustible material. The heat ignites it, and covering the bucket limits oxygen. Depending on the glaze, this can produce metallic flashes and shifting colors, while smoke darkens exposed clay and highlights crackle lines.
🫧 OBVARA
A different process often explored alongside Raku, Obvara uses a fermented mixture of flour, yeast, sugar, and water. Hot, unglazed pottery is dipped into this brew, which scorches against the surface, creating toasted browns, smoky patches, and wonderfully unpredictable patterns. A dip in water stops the action and preserves the markings.
🪶 HORSEHAIR + FEATHERS
Horsehair and feathers are applied to the hot, unglazed surface, where they burn and leave carbon markings. Horsehair creates wandering black lines, while feathers leave soft, smoky impressions. No glaze needed—the burning materials create the decoration.
Temperature, timing, and placement all influence the results. We can guide the process, but we never have complete control—and that’s part of the excitement.
Thank you to everyone who joined us to experiment, learn, and share that moment of surprise when the finished surfaces were revealed. 🤎
Which finish would you try? Obvara is my favorite.
