Well potted with shallow rounded sides supported on a gently tapering foot, painted in translucent green enamel within underglaze-blue outlines, the interior with a central medallion enclosing a five-clawed dragon writhing amongst flames in pursuit of a flaming pearl, its sinuous body carefully picked out with scales and its muscular legs terminating in powerful sharp claws, all within double-line borders in underglaze-blue repeated at the rim, the exterior similarly decorated with a pair of five-clawed dragons striding amongst flames in pursuit of flaming pearls, the base inscribed in underglaze-blue with a six-character reign mark within a double circle.
