Ishida Kazuya Cup 180 ml

Stoneware, wood-fired, mineral blue

8.8 cm (H) x 8.6 cm (W)

This cup is by Ishida Kazuya of Bizen and impressively demonstrates how raw porcelain clay and subtle color nuances come together in wood firing. The small bowl has an archaic, rough surface with crystalline areas reminiscent of weathered stone.

The color ranges between cool grays, warm tones, and mineral, almost chalky layers that form during the multi-day wood firing. Ash particles have settled irregularly on the surface and fused into glassy inclusions in the fire—leaving behind a texture that appears naturally grown.

This piece combines Bizen tradition, wood-fired character, and modern material aesthetics and is ideal for sake, tea, or as a collector's item. The cup comes in a hand-signed wooden box (tomobako).
