The peachbloom glaze was notoriously difficult to achieve. To manage the fugitive copper-lime pigment, it is believed to have been sprayed onto a layer of transparent glaze and then fixed with another layer, so as to be sandwiched between two layers of clear glaze. The technique marks one of the great ceramic innovations of the Kangxi period, but probably due to this demanding process, it remained in use for only a short time and was never revived again at a later stage.
A comparable peachbloom washer in the Palace Museum, Beijing, is illustrated in The Complete Collection of Treasures of the Palace Museum. Monochrome Porcelain, Hong Kong, 1999, pl. 19; another is published in Kangxi Porcelain Wares from the Shanghai Museum Collection, Hong Kong, 1998, pl. 208.
