Bizen Kuro Rock glass

This is a newly kiln-unloaded Bizen Black rock glass by Jun Isezaki, a Living National Treasure whose creativity never runs dry and who continues to lead the world of Bizen ware.

It is his latest work, unloaded from the kiln in February 2026.

Fired for about ten days in a semi-underground anagama, this piece brings together black slip and intense Goma in a dramatic collision, with parts of the surface transforming into blue fire effects derived from the cobalt in the slip.

This work was fired upright rather than laid on its side, and inside the vessel it has developed aurora-like flowing Goma and striking Tamadare.

Around the rim, where Goma tends to gather most heavily, scorched Goma with blue fire effects has formed, creating a landscape that conveys the fierce energy of flame so characteristic of Jun Isezaki’s dynamic firing.

With its smooth black coloration in the exposed clay areas and its exceptionally bold, energetic form, this piece feels like a concentrated expression of the appeal of Jun Isezaki’s black works.

It will take approximately one month to make the wooden box, have him sign it, and prepare the piece for shipment.

He was born in Bizen City, Okayama Prefecture in 1936.
He graduated from Okayama University in 1959.
He was accredited as a Living National Treasure in 2004.
