Excavated from Kusado-Senken Site, Fukuyama City, Hiroshima Prefecture
13th century
Height 35.0cm, mouth diameter 14.0-14.8cm, body diameter 29.0cm, bottom diameter 18.3cm
　The neck of the mouth is rather thin and rises vertically, and the edge of the mouth rim is folded outward, already forming a ball rim. The surface of the bowl is polished by polishing. Two sunken lines have been drawn on the shoulder, but they are unintentional and not necessarily parallel to each other. The firing process is not very good. It has already begun to transition to oxidative firing, with red fire color appearing on the lower half of the body and the neck of the mouth.
