Japanese Bizen Ware Catch-All Dish | Ao-Bizen Sangiri Blue-Grey | Studio Mark | Yakishime Desk Tray | Wabi-Sabi Ceramic Bowl

Bizen-yaki (備前焼) produces six distinct surface effects through the control — or deliberate release of control — of the anagama kiln's atmosphere. Most collectors are familiar with the warm amber hi-iro and the golden goma sesame-ash speckling. This piece demonstrates something rarer: ao-Bizen (青備前), the blue-grey that forms when the kiln produces it, not the potter.

The process is called sangiri (桟切り): during the multi-day wood firing, the potter partially buries certain pieces in the ash and sand that accumulates near the kiln's firebox. This burial creates a local reduction zone — oxygen-deprived, carbon-rich — that drives the iron in the Bizen clay to a cool blue-grey rather than the warm amber of normal oxidation. The result is a surface that looks, in certain lights, more like weathered slate or aged pewter than fired clay. Against this cool ground, the passages of warm hi-iro visible on the exterior — where the piece was exposed above the burial sand line — create the characteristic Bizen tonal drama: cool and warm meeting at an edge that records exactly where the sand surface was.

The interior adds a botamochi (牡丹餅) — the pale circular zone left where a round refractory separator rested against the clay during kiln loading, blocking the ash deposit and producing a lighter disc at the bowl's center. This is the third fire mark on a single piece: sangiri grey, hi-iro amber, botamochi pale — a Bizen vocabulary lesson compressed into one functional object.

The form is a heavy, low bowl with four symmetrical V-notches cut into the rim — a classic multi-purpose dish form that Bizen has produced for centuries. The notches make it immediately useful: as a rest for incense sticks (each notch holds a stick at a slight angle over the bowl, which catches the ash), as a ring and key dish by the entrance, as a sake cup holder or sencha tray, or simply as a desk catch-all where keys, coins, a ring, or a clip find their natural resting place at the end of the day. The weight and the rough, honest surface of the yakishime clay give it the kind of presence that cheap trinket dishes never achieve.

The base carries a geometric studio mark — two overlapping triangles, △ over ▽, pressed into the raw clay before firing by hand. Geometric marks of this type were favored by independent studio potters in the Bizen region during the Showa and Heisei periods who preferred a visual identity to a kanji signature. The mark is deliberately composed and cleanly executed.
