Vintage Japanese Kuro-Oribe Style Chawan, Black Glaze with Iron-Painted Window, Matcha Tea Bowl, Wabi-Sabi

A BLACK BOWL THAT OPENS A WINDOW

The glaze is a deep, glossy blue-black. Across it, angular lines and a single sweeping curve cut through to the pale clay below, like a drawing made in shadow. Turn the bowl and a window opens: a patch left free of black glaze, painted in iron brown flecked with rust, and covered by a clear glaze. The bowl itself leans out of round and pinches at the waist. This is a vintage Japanese chawan (tea bowl) in the Kuro-Oribe style (黒織部), the black Oribe of the Mino tradition.

WHAT IS KURO-ORIBE?
Kuro-Oribe (黒織部) is a black style of Oribe ware, made in Mino (modern Gifu Prefecture) in the Momoyama and early Edo periods. Traditionally, the iron glaze was pulled red-hot from the kiln and cooled quickly so that it turned a lacquer-like black. A plain black bowl that is deformed or clog-shaped is called Oribe-guro (織部黒). When the bowl also carries decoration, such as bare windows painted in iron and covered with a white or clear glaze, or patterns carved into the black glaze, it is called Kuro-Oribe.

IS THIS A TENMOKU BOWL?
Not in the strict sense. A classic tenmoku (天目) bowl is shaped like a mortar, with a lip that narrows and then flares out. This bowl is a rounded, slightly deformed Oribe-style form. It shares the black iron glaze with the tenmoku family, which is why the word is sometimes used loosely for any black glaze.

HOW THIS BOWL RELATES
The structure follows the classic Kuro-Oribe recipe: black glaze, a window left bare and painted in iron, linework cut into the black, and clear glaze below. We describe it as Kuro-Oribe style because we have not confirmed the kiln or the firing method.

THE WABI-SABI DETAILS
The bowl leans, the waist pinches, the linework is bold and the iron painting is speckled with rust. Oribe tea ware was prized for exactly this kind of deliberate imperfection.

DISPLAY AND USE
