While a delicate celadon glaze had already been developed in the Kangxi reign, it was during the Yongzheng period that the production of glazes imitating Song dynasty Ru and Guan wares greatly expanded. According to the 1732 edition of the Jiangxi Tongzhi (Jiangxi provincial gazetteer), compiled by Xie Min, governor of Jiangxi Province between 1729 and 1732, two different types of Ru-type glazes were developed, one displaying a subtle network of crackles and the other of even tone; see S.W.
