Directory of Tetsubin Makers

The tetsubin is a cast iron kettle for boiling water, used in Japan for sencha and later for everyday tea. Antique kettles are collected for their casting, their lids and the quiet relief decoration on their bodies. This directory introduces the workshops and regions whose names appear most often on kettles and their boxes.

The Kyoto workshops

Kyoto foundries produced many of the most refined kettles of the nineteenth and early twentieth centuries, often with bronze or silver inlaid lids and elaborate handles.

• Ryūbundō (龍文堂). The most celebrated Kyoto name, founded in the eighteenth century and continued through several generations. The mark 龍文堂造 is widely copied, so the casting itself matters more than the stamp.
• Kamebundō (亀文堂). Known for crisp relief landscapes and figures cast into the body, frequently with fine bronze lids.
• Kinjudō (金寿堂). Another respected Kyoto foundry, associated with elegant forms and well finished lids.

Nanbu ironwork in Iwate

Morioka and Mizusawa in Iwate prefecture have cast iron since the Edo period, and the name Nanbu tekki, Nanbu ironware, is now a protected traditional craft. Nanbu kettles tend to be sturdier, with the familiar hailstone pattern of raised dots, arare, across the body.

• Suzuki Morihisa (鈴木盛久). A Morioka family workshop of many generations, whose kettles are prized for their restrained forms.
• Iwachu (岩鋳). A large Morioka foundry founded in the early twentieth century, best known abroad for its enamelled teapots.
• Kunzan and other studios. Many smaller Morioka makers sign kettles and boxes with art names, which can be checked against their known marks.

Reading marks and lids

Marks are usually cast under the handle lug or on the base, and lids are often signed separately by the bronze maker. A lid by a named artist adds real interest. Kettles were sometimes paired with replacement lids over their working lives, so a lid that matches the body in date and style is worth noting.

Kettle or teapot

A true tetsubin is unlined and is made for boiling water over heat. Iron teapots, tetsu kyūsu, have an enamelled interior and are meant for brewing tea, not for direct heat. Most antique kettles are tetsubin, and most modern enamelled pieces are teapots.

Condition notes

• Light rust inside an old kettle is normal and is usually stable mineral scale.
• Cracks, pinholes and repaired handles affect both use and value, so check the base against light.
• Original fitted boxes with inscriptions add provenance and can help to date a kettle.
