QIANLONG PERIOD, LATE 18TH CENTURY, THE FRAMES MODERN

THE ART OF REVERSE-PAINTING
The practice of painting on mirrors developed in China after 1715 when the Jesuit missionary Father Castiglione arrived in Beijing. He found favor with the Emperors Yongzheng and Qianlong and was entrusted with the decoration of the Imperial Garden in Beijing. He learned to paint in oil on glass, a technique that was already practiced in Europe but which was unknown in China in 1715. Chinese artists, already expert in painting and calligraphy, took up the practice, tracing the outlines of their designs on the back of the plate and, using a special steel implement, scraping away the mirror backing to reveal glass that could then be painted. Glass paintings were made for export, fueled by the mania in Europe for all things Chinese. Although glass vessels had long been made in China, the production of flat glass was not accomplished until the 19th century. Even in the Imperial glass workshops, set up in Beijing in 1696 under the supervision of the Bavarian Jesuit Kilian Stumpf, window glass or mirrored glass was not successfully produced. As a result, from the middle of the 18th century onwards, when reverse glass painting was already popular in Europe, sheets of both clear and mirrored glass were sent to Canton from Europe to be painted.
