 The thick neck of this jar has an 8mm rim band with the apex of the neck turned outward at a right angle, and the body is shouldered, a mid-twelfth-century form. The body is shawl-shouldered and of mid-twelfth-century form. The body is covered with three sunken lines in regular positions, showing the stylized form of a three-striped jar. The body is gray in color, and although it is well fired, it has cracks on the body due to the strong heat. The dark green natural glaze runs down from the shoulder to the body.
