A close comparison, however, from the Qing court collection, is in the Palace Museum, Beijing, a smaller washer also of this five-lobed prunus shape, with two raised ribs on the outside and with very similar incised decoration, illustrated in The Complete Collection of Treasures of the Palace Museum: Porcelain of the Song Dynasty, Hong Kong, 1996, vol. 1, pl. 84, where it is noted that this shape and design were imitated by the Jingdezhen kilns in yingqing (qingbai) ware. The flower on the Beijing washer is described as hibiscus, but its bloom and leaves, like those on the present piece, seem closer to traditional depictions of the tree peony.

The Beijing washer is illustrated again, together with a second washer of similar form in the Palace Museum, also smaller size, without raised ribs and decorated with an incised dragon medallion and key-fret borders; see Ding ci ya ji. Gugong Bowuyuan zhencang ji chutu Dingyao ciqi huicui/Selection of Ding Ware. The Palace Museum’s Collection and Archaeological Excavation, Palace Museum, Beijing, 2012, pls 45 and 46.
