Kondo Seiko (b. 1945) trained under the Karatsu legend and scholar, Koyama Fujio, whose research into Chinese glazes played a major part in defining the visual identity of modern Karatsuyaki today. Kondo has a nice pictorial sense. In this cup, the clay has a nice gradation from pale to a firey red. You can see that he has used an iron slip to cleverly impress a thumbprint on one side, giving a playful geometric aspect to the cup. The color is warm and tender. He fires using a noborigama (climbing kiln), and other experimental hole kilns.
