Height 34.6 cm, mouth diameter 15.6-17.0 cm, body diameter 27.8 cm, bottom diameter 19.2 cm
　This jar has a short, upright mouth rim with a ball-shaped rim, and was probably used as a seed pot. It was made of slightly sandy clay, and the surface of the vessel was formed by rolling up the clay and using the soma (a thin layer of clay) vertically on the lower half of the body and horizontally on the upper half, but the shaping is not very good. Two sunken lines are randomly drawn on the shoulder. The ware is not very hard. The firing is still in the reduction stage, and the surface is grayish in color.
