Kuro Guinomi

Koichiro Isezaki is Jun Isezaki's eldest son.
He uses a tunnel-shaped kiln called an "anagama."
This work was created around the time indicated in the included artist’s résumé, which dates up to 2014.
This earlier work by Koichiro Isezaki is coated with black slip yet placed in a position within the kiln where Yohen (kiln-transmutation) effects could develop, resulting in a surface that combines the qualities of both black ware and Yohen-fired pieces.
Around the shell marks and inside the cup, the tones lean more toward purple or brown rather than pure black. On the front near the shell marks, Kinsai (gold-like coloring) appears, showing a strong Yohen character.
In contrast, the natural ash glaze that adhered to the mouth has transformed into a cobalt blue due to the black slip, and when in use, it will deepen to an even richer blue as it absorbs moisture.

He was born in Bizen City, Okayama Prefecture, in 1974 as the eldest son of Jun Isezaki.
He graduated from Tokyo Zokei University in 1996.
He studied ceramics in NY and has been active since 2000.
