Schoonmaker, acquired prior to 1887. Collection of Job Male (1808-1891).Francis X. Schoonmaker收藏，得於1887年之前Job Male (1808-1891) 收藏The form of the present vase, modeled after ritual jade cong, is more commonly found in monochrome glazes. The underglaze-red decoration, much favored during the early Ming dynasty but virtually abandoned after the Xuande period due to the very high failure rate during firing, was revived and mastered in the early Qing dynasty, around the 1670s in the Kangxi period. It became a standard practice although successful firing of the copper pigment remained particularly difficult hence wares decorated in this manner continued to be made in small quantities.The Qianlong Emperor is known to have been a great admirer of archaic jades, and his collection surpassed that of any of his predecessors. It is therefore unsurprising that he would have commissioned the making of vases in shapes devised from jade prototypes. The present vase demonstrates a fusion of the the archaic form, cong, with a contemporary design, replete with symbolism. Bats have traditionally been the symbol of good fortune, and red bats were especially auspicious, red being the color which wards off demons and is homophonous with the word 'enormous' (hong), indicating especially great fortune. Only a small number of copper-red Qianlong vases of this type is known, including one from the W.W.
