During the early-Qing dynasty, in 1696 the Kangxi Emperor invited the skilled German Jesuit missionary Bernard Kilian Stumpf (Chinese name Ji Li’an) to provide technical guidance in the establishment of the Qing palace glass workshop. From this time forward, the Qing imperial workshop produced many fine articles of glass. Qing imperial glassware may be classified into several different categories, namely: monochrome glass (danse), flashed glass (taose), aventurine glass (jinxing), blended-color glass (jiao), gold-inlaid glass (qiangjin), glass-substrate enamels, etched glass, ground glass (mohua), and spotted glass (diancai).
