Jian ware tea bowl (jianzhan)
A dark-glazed conical stoneware bowl from Jianyang in Fujian, whose iron-saturated glaze separates during firing into streaks or spots. It was made for whisked powdered tea and the colour is functional: white froth on a near-black ground is easy to read, and judging the froth was the point of the contest the bowls were made for.

Porosity
Not porous. It contributes nothing of its own to the liquor, so it can be moved between teas freely and washed with detergent without consequence.
The glazed interior is inert. The body is thick, unglazed at the foot and coarse, which matters for handling rather than for flavour — an unglazed foot ring holds water and must be dried before the bowl is stacked or stored.
Where it comes from
Chinese, from Jianyang in Fujian, and conventionally dated to the Song period when tea was whisked from powder rather than steeped. Japanese practice adopted these bowls under the name tenmoku and they acquired a separate significance there. TeaHQ gives the conventional dating without asserting a specific year.
Named here rather than presented as generic equipment. The object belongs to a practice, and TeaHQ describes it from the outside.
If you do not own one
Any chawan whisks matcha equally well, and a pale interior arguably shows the foam better than a dark one does for a beginner learning what a good suspension looks like. The dark bowl is a historical form and a beautiful object, not a technical advantage.
This one is not marked essential. The tea can be made without it.
Brewing methods it is used for
- Whisking (bowl-prepared powdered tea) — Powdered leaf suspended in water rather than steeped and strained — the only common preparation in which the leaf itself is consumed rather than discarded.

Care and maintenance
Rinse and dry, including the raw foot. These bowls are heavy and thick, so they tolerate heat well and drops badly. Glazes with visible metallic sheen should not be scoured.
