I've chosen to classify this as belonging to the Qing
dynasty reign of Yongzheng (1723-35) since it was during
this reign that doucai reached both it's height in production and perfection.
Though doucai ware was first thought to have originated during the reign
of the Ming emperor Chenghua
(1465-87), shards have since been unearthed from
the Xuande (1426-35) stratum at Jingdezhen during
excavation. The origin of this design however is Chenghua. Information
on other examples regarding this specific design and style is listed
