Una Mistura is a striking example of Ryūichi Kakurezaki’s sculptural approach to the tea bowl, merging bold form with the subtle unpredictability of wood firing. Built with his signature angular, hand-modeled construction, the vessel presents a square, gently twisting body whose surfaces shift between deep indigo tones and earthy browns. A dramatic, glossy patch of natural ash glaze pools across one face, revealing the intense heat and atmospheric conditions of the kiln. The interior retains a dark, burnished texture that contrasts with the rugged exterior, emphasizing the tension between refinement and raw materiality that defines Kakurezaki’s work.
