Of square form, decorated with yellow-glazed on the biscuit, in an archaistic shape with lobed sides and a square opening. It has a small lizard-like qilong dragon picked out in aubergine brown, crawling up the side, his head resting on the edge of the opening. The underside is enameled in yellow. The pot is very black on the inside, which indicate it has actually been used to wash inly brushes. As it is of small size, it could have been used as a water dropper, as well as a washer.
