 This small water jar with a large, flattened mouth dates to the end of the 14th century. It is made of grayish-white dense clay, water-ground and molded, and has a thread cut on the back. There are chink lines on the shoulder and body. The ash glaze is well melted and evenly applied, but there is a large amount of feldspar in the glaze, giving it a bluish-white color.
