ANOTHER PROPERTY A RARE ' RU -TYPE' CONG -SHAPED VASEQianlong seal mark and probably of the period The heavily potted vessel imitating the archaic jade cong form, supported on a circular short foot with two pierced apertures, the straight sides molded to the corners with raised trigram-like bands, one side pierced with two pairs of holes, all under an unctuous Ru-type glaze stopping at the dark-dressed foot rim, with an underglaze blue seal mark. 11 1/4in (28cm) high 或為清乾隆 仿汝窯八卦琮式瓶 青花《大清乾隆年製》三行篆書款 Such vessels as these are modelled on Song dynasty vases of the same form, which in turn are based on Neolithic jade cong . The present vase appears to be in imitation Ru ceramics rather than those of Guan or ge type that are more regularly published. Most eighteenth century cong -shaped vases are molded with the 'Eight Trigrams' design around the entire body, so the unusual inverted U-shaped design on each facet of the present vessel and the additional paired apertures on one side, makes our model quite rare. See twoparable Ru -type cong vases of the same size and design, one sold at Christie's, Hong Kong, The Imperial Sale, June 3rd, 2015, lot 3108; and the other at Sotheby's Paris, December 15th, 2011, lot 98.
