(2)The peachbloom glaze has been the focus of scientific research since the mid-20th century. Both the overall soft pinkish red of the glaze, and the areas of clear green which appear to a greater or lesser extent within it owe their hue to copper. Firing in a reducing atmosphere creates the red color, while re-oxidation creates the green. This was therefore a glaze that had to be applied very precisely and fired with great care. Research suggests that a copper-lime pigment was applied between two layers of colorless glaze. The copper-lime pigment was applied by blowing through a bamboo tube with fine silk gauze over the end, to achieve an effect similar to modern spraying techniques. This allowed the thickness of the copper-lime layer to be adjusted so that some areas would be thicker than others. In those thicker areas, there was additional flux, which thinned the upper glaze layer and allowed the copper to re-oxidize and produce clear green. In the other areas, some of the pigment was undissolved making it appear slightly opaque and yet smooth on the surface, while the majority of the copper did dissolve and produced a rich pinkish red and creating one of the most highly esteemed glazes from the Qing imperial kilns.Auction resultparison:Type: RelatedAuction: Christie’s New York, 23 August 2017, lot 189Price: USD 4,000 or approx.EUR 4,500 converted and adjusted for inflation at the time of writingDescription: A Chinese peachbloom-glazed 'chrysanthemum' vase, juban ping, late Qing dynastyExpert remark:pare the related form, glaze, and apocryphal Kangxi mark.
