This object is flat and round, with a pair of ring ears on its shoulder. At the two sides of the belly are inscribed five concentric circles double lines. The circles extend from the center and intervals between circles are filled with lines like water waves. The whole picture gives an impression that ripples appear when a stone is thrown into the water. The whole object is covered with blue and yellow glaze. The polished and shiny surface is close to products made with mature celadon-making techniques. The whole object is made in a regular shape with a new sculpt. Such an object is rarely seen among celadon articles produced in the Eastern Han Dynasty.
