A Hirado-type Kogaratsu dish fired from 1610-30s. The iron glaze and the ash glaze contrast like a Yin and Yang, leaving sand spur marks on the front face and the foot. The bicolour design was mainly manufactured in kilns that also produced porcelain (Imari ware), such as the Seirokuno-Tsuji kiln. The deep hat-shaped form is also suitable for a flat sake cup.

There are three gold repairs and a hairline on the rim, but it is in good condition as an old excavated piece. It fits in a box labelled “Karatsu Katamigawari (bicolour) Chawan”.
