Jingdezhen's chemists and thermal engineers are highly skilled and there is no question of going back to the ancient manufacturing processes. A special effort is made to improve the green glaze imitating the color and transparency of jade, which is named qingci in Chinese and celadon in Europe. During the reign of Yongzheng several hues of celadon glaze are listed.
An amphora vase bearing the imperial mark of Yongzheng appears as a culmination of that development. It was sold for HK $ 17.4M including premium by Christie's in Hong Kong on November 1, 2004, a very high price at that time for a monochrome porcelain, and returns in the same venue on May 31, lot 2888.
The shape of this vase 52 cm high imitates vessels made of metal or porcelain in the Tang period, which are no longer amphorae of the antique type since the pointed lower end used to catch the vessel in its lower part for pouring the liquid has been replaced by a usual flat base for installation. He retains from these Tang models the two lateral handles in the shape of dragons biting the rim. The ornament of the neck simulating bamboo rings is a reference to the Northern Song.
Celadon is also an ancient symbol reminding the development of that glaze in the Longquan kilns under the Southern Song dynasty. The bluish-green glaze of this amphora, thick and translucent and leveled in the recesses, is indeed an achievement directly attributable to the engineering of the Qing.
