　This is one of the medium-sized jars belonging to the latter half of the 12th century. The rim of the mouth has begun to develop a slight rim band. The clay is gray and coarse in texture, with a three-tiered body. The surface is grayish black from reduction firing, and the entire surface from the neck of the mouth to the shoulders is covered with a bright green natural glaze.
