Goki chawan (tea bowls) are a type of Goryeo tea bowl from the Joseon Dynasty, fired on the Korean Peninsula. The name comes from their resemblance to the wooden bowls ("goki") used in Zen temples. They are characterized by their thin, large bowl shape, deep interior, and "bachi-kodai" (splayed foot). The clay contains iron, giving the bowls a reddish or brownish hue, and they are elegant and refined tea bowls. Size: 11.2 cm in diameter x 7.5 cm in height. Calligraphy: Kanjitsu Kawakami, the 10th generation of the Edo Senke school.
