White porcelain. Sui white porcelain double-bellied dragon handle bottle is made of white porcelain. The handles on both sides of the bottle body are two hand-made longkou, with a single neck and two slim dragon handles formed on the shoulder, which are arranged together with two oval bellies, which are parallel and double flat-bottomed.
