A excellent potted shape, a excellent glaze and Cobalt blue, a excellent execution of the decoration - this dish is definitely done in an Imperial quality.
Ming Chenghua mark but Qing Dynasty, probably of the Kangxi Period ( 1662 - 1722 )
There are also Daoguang dishes with a quite similar Dragon design but if this piece would be a Daoguang dish it most probably would bear a Daoguang mark.
Kangxi pieces often are marked with a Ming Quenghua mark - thus the Chenghua Mark on this dish together with a for Kangxi typical yellowish - ochre colored surface of the unglazed footring clearly points to the Kangxi period as dating for the dish.
Diameter :19,4 cm.
Condition : A short nearly invisible hairline which is to see on the last enlargement and 2 small shell shaped chips to the underside of the rim which however fortunately do not negatively impact the front view of this rare dish.
