Vintage Bizen Ware Vase, Goma Ash Glaze and Tamadare Drip Effects
This is a vintage Bizen ware (備前焼) stoneware vase in an unusual stepped, tiered silhouette — a distinctive variation on the traditional tokkuri form — its unglazed reddish-brown body marked entirely by natural wood-firing effects: goma (胡麻) ash speckling, tamadare (玉垂れ) drip streaks, and the dry, matte skin of kasegoma (かせ胡麻).
Cultural & historical narrative
Bizen-yaki, produced for over a thousand years in Imbe, Okayama Prefecture, is fired entirely without glaze — every mark on its surface is the product of ash, flame, and clay interacting inside a wood-burning kiln over firings that can run ten days or more. Three distinct effects are visible on this piece. Goma ("sesame") forms as melting pine ash speckles the surface with granular, glassy spots. Where enough ash accumulates and melts further, it runs down the body in glassy streaks — this flowing stage is called tamadare ("bead-dripping"), visible here cascading from the shoulder down toward the base. And where ash clings to the surface after losing its moisture in the heat, it leaves behind a dry, matte, almost stone-like skin known as kasegoma — a drier cousin of goma long prized in tea ceremony circles for its restrained, wabi character. No two Bizen firings ever produce the same combination, making the specific arrangement of effects on this vase entirely unrepeatable.
Attribution note
The unglazed iron-rich body and combination of goma, tamadare, and kasegoma effects are strongly consistent with Bizen ware from Imbe, Okayama Prefecture. No maker's mark is visible in the available photo, so kiln or artist could not be determined.
Care + closing
Bizen ware is unglazed and slightly porous — wipe clean with a dry or barely damp soft cloth; avoid soaking or dishwasher use. A quietly striking piece for collectors drawn to Bizen ware's natural firing effects and unrepeatable surface character.
