Qing Bowl 17th Century

The photos don't show enough detail and there's some glare, but here goes: The reign mark is for Shunzhi the first emperor (1644-61) of the Qing Dynasty. Authentic items bearing the imperial seal of Shunzhi are so exceedingly rare that some experts say they are nonexistent. The chaos caused by the fall of the Ming Dynasty (1368-1644) led to the destruction of the main kiln sites at Jingdezhen, and porcelain production didn't really pick up again until mid-way through the reign of Kangxi (1662-1722). Therefore, genuine mark-and-period Shunzhi imperial wares may not even exist, according to some experts. It is believed that the earliest appearance of the Shunzhi mark is on pieces dating from the Yongzheng-era (1722-35), a "tribute" practice, which continued under Qianlong (1736-95). If that is the case here, what you have is still a fine 18th century Chinese Qing Dynasty blue and white porcelain bowl, complete with dragons. There is the small chance that it could be of 19th manufacture, but I don't think so. By the way, who looked at it on Antiques Roadshow? Was it Lark Mason?
