Half cylinder shaped (Hanzutsu) tea bowl, thrown from light, coarse Mino clay, with very little inclusions a clay found on earlier Shino bowls. The walls are cut with a potters knife.
The bowl has been covered fully (with the exception of the foot ring) first with an iron bearing engobe (oniita) and after the decoration had been incised with the typical ash and feldspar glaze inside and outside creating the nezumi-shino glaze.
The decoration in white Shino glaze on this bowl are a circle, a triangle and a rectangle, rarely seen on antique tea bowls and very symbolic in the iconography of Zen buddhism, with many interpretations. Very famous is for example the zenga by the Rinzai monk Sengai Gibon (1750-1837), published by the Zen philosopher Suzuki Daisetsu (Daisetz) under the title 'Universe'. Please refer to picture no. 10.
The bowl comes with a very good wood box and a fine shifuku.
No cracks or repairs.
Size: 8,3 cm height x 11,6 cm in diameter.
