The use of this visual also pops up on traditional and modern pottery. This Nezumi-Shino chawan has the circle/square/triangle carved through a rich iron slip and then glazed over in a wonderful feldspatic Shino glaze. The illustrated chawan is by Mino veteran potter Mizuno Takuzo. I am particularly fond of this style of Shino glaze and the development of thick glaze cells moving in a diagonal indicating the direction the bowl was thrown. Overall, a very sober and engaging bowl with a design that brings the viewer around the bowl and into its interior.
