This celadon jar has a circular lid with a knob shaped like a bird looking back, a dish-like mouth, a contracted neck, a round swelling belly, and a flat bottom. It has a grayish white body that is coated outside with bluish yellow glaze. Stuck on its upper belly are four animal head ornaments (pushou), two Buddha statues, and a pair of two-headed birds. They are arranged orderly with proper intervals and sketched in brown color. Brown patterns are painted on the body of the jar with running and lively strokes. The jar is the earliest object found so far in China that was beautified using painting techniques. It can be called an art treasure among China’s early porcelain products. The superb underglaze painting technique ofthis jar, which was unearthed in 1983,has overthrown the previous theory that the underglaze technique did not appear until the Tang dynasty, thus advancing the appearance of this technique in China for nearly 500 years.
