The green glaze, also known as lülangyao (green langyao) or green-Ge, was one of the many glazes produced by the Jingdezhen kilns under the supervision of Lang Tingji, Governor of Jingdezhen, during the years, 1705-1712, of the Kangxi era. This glaze is generally considered to be a transmutation of Langyao red to green, due to the oxidisation of copper in the last stage of the firing which yields a light green rather than a red hue. A more in depth discussion of this glaze is discussed by Q. Wang, in A Dictionary of Chinese Ceramics, Shanghai, 1989, p. 223.
