Only very few Yongle porcelains with this delicate, clear, bluish-green glaze have survived, including two Yongle jars of the same form in the Qing Court collections. The jar in the Palace Museum, Beijing, which measures 14.1 cm. across its base is illustrated in Monochrome Porcelain The Complete Collection of Treasures of the Palace Museum, Hong Kong, 1999, p. 134-5, no. 123, where the glaze colour is described as cuiqing, bluish-green or jade green. The example from the National Palace Museum, Taipei, which measures 12.3 cm., is illustrated in Porcelain of the National Palace Museum, Monochrome Ware of the Ming, Book I, Hong Kong, 1968, p. 50, pls. 10, 10a and 10b, where the colour of the glaze is described as dongqing, 'winter green'. An almost identical example, also with three biscuit florettes on the shoulder, was sold at Christie’s New York, 16-17 September 2010, lot 1357.
