QIANLONG IMPRESSED SIX-CHARACTER SEAL MARK AND OF THE PERIOD (1736-1795)

Advances in technology and experimentation at the Imperial kilns during the 18th century led to the introduction of various new intriguing monochrome glazes. The 'Robin's-Egg' glaze is generally thought to have been developed as a reinterpretation of Song dynasty Jun glazes.

The robin’s egg glaze is more commonly seen on forms like lantern vases, see one in the collection of Musée Guimet, Paris, illustrated in Oriental Ceramics: The World's Great Collections, New York, 1980-82, vol. VII, fig. 184. A vase of the same form as the current vase can be found on other Qianlong period monochrome wares, see a celadon-glazed relief decorated vase, sold at Christie’s New York, 21 March 2014, lot 2182.
