AN OVERLAY YELLOW AND TURQUOISE-GROUND GLASS VASE MARK AND PERIOD OF QIANLONG

deeply carved through the bright yellow to an opaque turquoise ground, the globular body decorated with a continuous scene depicting a pheasant perched on a rocky boulder, the rockwork extending to slender branches issuing camellia, peony and narcissus blooms and their associate foliage, the leafy stems extending to the cylindrical neck, all resting on a slightly flared foot, incised on the base with the four-character mark within a double-square

There are three small losses and minor nibbling to the carving, the largest to the tip of the flower petal. Otherwise the vase is generally in good condition overall. There is characteristic pitting and black speckling.

The present vase is unusual for the combination of turquoise and overlay yellow which creates a striking contrasting effect.  It also belongs to the group of globular vases which are normally made in monochrome colours, and which are very rarely seen in overlay decoration.       

Compare two related glass vases with overlay in which the decoration extends from the body to neck, in the Asian Art Museum of San Francisco, illustrated in A Chorus of Colors, Hong Kong, 1995, pl. 93 and 94.  See also a pair of vases with the same unusual colour combination, but without the Qianlong mark, sold at Christie's London, 28th April 2003, lot 714.
