[What is Shino Ware?] It is said to have originated when the tea master of the Muromachi period, Shino Soshin, ordered the Mino potters to make it. It is produced from Kukurikani City to Izumicho, Toki City, using fire-resistant, less-baked Gotomaki clay and Mogusa clay, which are low in iron and have a slightly purplish or pinkish white clay base. It is thickly glazed with Shino glaze (feldspar glaze), which is made by crushing and refining feldspar. Usually, the glaze surface has fine cracks and yuzu-like texture, as well as many small holes. The glaze edges and the rim, where the glaze is less applied, show a reddish scenery called "hiiro" (fire color). The Shino tea bowl, named Unohana-gaki (owned by the Mitsui Memorial Museum), is one of only two national treasures (designated in 1959) among domestic tea ceramics (the other is Hon'ami Koetsu's Raku ware white katami-gawari tea bowl, named Fujiyama).
