Sandbanks Antiques has dated this Qianlong Flambe Brush Washer to the 18th Century.
Jingdezhen Kilns, Qing Dynasty, 18th Century (Qianlong Period)
The elegantly compressed, low-slung body is enveloped in a mesmerizing, rich plum-purple yaobian (flambé) glaze, heavily suffused with opalescent streaks of lavender, cosmic blue, and sea-green flecks that pull cleanly away at the incurved rim. In striking contrast, the interior features a classic, widely crackled cream 'Ge'-type glaze, harmonizing multiple ancient Song dynasty aesthetics into a single masterpiece.

Fitted with an immaculate, uniform chocolate-brown zijin iron slip to the recessed base—a technical hallmark of elite 18th-century imperial studio production—this remarkably lightweight vessel boasts an illustrious, undisturbed Japanese collection provenance. Fully vetted under ultraviolet light, the piece survives in museum-grade, pristine condition, making it a premier acquisition for the discerning connoisseur of Chinese scholar's works of art.
