The emerald pearl cup

Wild clay, stoneware and porcelain cup, wood-fired for two days and two nights. It shows intense wood-firing effects, with ash rivulets and a precious emerald colour pearl of molten ash, known in Japanese as “bidoro”. Fossilised shells mark the spot where the piece was standing during the firing, and leave space for the ash passages to go around the piece.

The dark and rich wild clay foot contrasts with the lighter stoneware and porcelain engobe of the top part of the piece. At the very top, as well as the inside, there’s light pink tones from volatilized copper.

The accumulation of volatilized ashes during the firing formed a stunning crystalline pool on the inside, making of this cup a unique and extraordinary piece for a true luxurious everyday.
