This distinctive glaze seeks to recreate the famous classical Jun wares of the Song period. The splashes and streaks characteristic of this glaze are described as yao bian, or 'transmutation glaze', and has been the subject of much research. See R. Kerr, Chinese Ceramics: Porcelain of the Qing Dynasty 1644-1911, p. 75, and N. Wood, 'The Evolution of the Chinese Copper Red,' in R. Scott (ed.), Chinese Copper Red Wares, Percival David Foundation of Art, pp. 29-30, for a discussion on this topic.
