Pair of Bizen-yaki tokkuri vases, Shibaoka Tōsendō, Kōzan-gama kiln, Imbe

€85.00

Two small teardrop vases, narrow at the neck and full through the shoulder, standing close enough together that they read as a pair without being identical. One leans toward deep aubergine with a soft silver mist rolling across the front, almost metallic where the light catches it. The other runs cooler still, a wash of silvery blue-grey shifting into warm rust low on the body. Neither would look complete alone. Together they hold a conversation, one leaning warm, the other leaning bright.


Both carry the maker's mark of Shibaoka Tōsendō, working under the kiln name Kōzan-gama in Imbe since 1912. The kiln has stayed in one family for three generations, currently the third-generation Kōzan, Shibaoka Masashi, working alongside his sons Chikara and Hisashi. A pair like this, thrown at the same time and fired side by side in the same noborigama, is a small, physical record of one firing at a kiln that has kept its own fire burning for over a century.

→ Fourteen days, one fire: what it actually takes to fire a Bizen kiln. A visit to Shibaoka Tōsendō during an active firing, standing at the kiln mouth while the family read the fire by eye and ear alone. Read the full visit in my journal.

What makes this Bizen duo special

The up close look and feel

Both vases share the same dry, slightly speckled clay body under the fingers, cool and dense. The narrower vase carries a soft, almost velvety sheen where the sangiri effect runs deepest. The fuller one is rougher at the shoulder, where ash settled thickest during the firing, and smoother lower down where it did not.

Charming details

Set side by side, the two vases catch light differently: the left holds a warm, even glow from every angle, while the right carries a genuinely silver sheen across its widest point, the kind of subtle metallic quality collectors specifically look for in strong sangiri. That difference comes down entirely to where each one sat in the noborigama. Two vases, one firing, two completely different records of the same two weeks in the kiln.

Hidasuki, goma, sangiri, shiro-Bizen: four names for four completely different things the fire can do to the same clay. These two vases carry the combination of sangiri and goma, where ash and reduction work the surface from opposite sides of the same firing. → Here's what each one actually means.
