HENAN RUSSET-PAINTED BLACK-GLAZED JAR NORTHERN SONG TO JIN DYNASTY 北宋至金 河南黑釉鐵鏽花鳳紋瓶 the globular body rising to pronounced rounded shoulders and surmounted by a narrow flanged neck, freely painted on the exterior in bold russet-iron brush strokes with stylised phoenix or bird motif against a thick, glossy black glaze, extending to the interior and the base, leaving only the foot ring unglazed, revealing the pale brown stoneware body (21.5cm high) Qty: (1) Note: Ovoid jars of this type, with this distinctively small, double-ringed mouth, are termed xiaokou ping (small-mouthed bottles), and were probably used for storing wine and other liquids. Typically dark-glazed, such bottles are often painted in russet and in this instance decorated with an abstract phoenix design. Birds in flight, or abstract floral decoration, rendered with vigorous, calligraphic strokes, are also characteristics of these jars. A jar of this type, with floral decoration rather than the birds on the shoulder of the present jar, in the collection of Dr Robert Barron, is illustrated by R.D. Mowry in Hare's Fur, Tortoiseshell, and Partridge Feathers, Cambridge, 1996, p. 165, no. 55, and subsequently sold at Christie's New York, 30 March 2005, lot 303.
