The bronze lost wax casting technique of imitating ancient bronzes refers to the use of special craftsmanship by artists to combine casting, painting, carving, and inlaying to imitate ancient bronzes and other cultural relics for people to appreciate and collect. The history of Suzhou bronze production can be traced back to the Wu Kingdom in the Spring and Autumn Period, and the imitation of ancient bronzes can be traced back to the Song and Yuan Dynasties. In the Ming Dynasty, Suzhou's imitation of antique bronzes was famous for "Su Zhu". During the Wanli period, Suzhou had a copper worker Hu Si who "cast Yi Ding and other utensils in imitation of the ancient, and it was indistinguishable from the old castings". During the Wanli and Tianqi periods, Cai Wenfu's imitation of ancient bronzes was called "Su Zhu". During the Qianlong and Jiaqing periods of the Qing Dynasty, there were also many experts. The imitation bronzes were identical to the originals in shape, inscriptions, patterns, thickness, weight, color, etc., reaching the point of being indistinguishable from the originals. Since modern times, Suzhou has been one of the important bases for the production of imitation antique bronzes, and has formed the regional characteristics of "Suzhou made". From the late Qing Dynasty to the Republic of China, Suzhou's famous craftsmen of imitation antique bronzes included Zhou Meigu and Liu Junqing. The whole thing is fake, and Zhou Meigu is the best. In 1921, Zhou Meigu opened an antique bronze workshop, using the lost wax method to imitate ancient artifacts such as tripods, Yi, You, and Gong. Their antique bronzes are so realistic in shape, decoration, inscriptions, thickness, weight, copper composition, chiseling, and skin color that they are indistinguishable from the real thing. After the outbreak of the Anti-Japanese War, the production of antique bronzes in Suzhou was interrupted for more than 20 years. In 1956, Suzhou Arts and Crafts Research Institute purchased the wooden templates of the antique bronzes from Zhou Meigu's workshop, and in 1958, they found Luo Qiyue, Li Hanting, Liu Youfu, and Jiang Shengbao, who had worked in Zhou's workshop, and recruited several apprentices to resume the production of antique bronzes. In the 1970s, a number of imitation bronzes such as "Four-legged Gong with Bird and Beast Pattern", "Phoenix Pattern Gui" and "Gold-Inlaid Human Face Pot" were produced, and precious unearthed bronzes were reproduced for museums in various places. After entering the 21st century, the production of imitation bronzes in the original ancient city basically stopped, but several imitation bronze production companies appeared in the surrounding areas such as Xiangcheng and Wuzhong. At the same time, Suzhou Arts and Crafts Vocational and Technical College conducted a special study on the production techniques of Suzhou imitation bronzes. The production of imitation bronzes goes through the following steps: (a) mold making, (b) sample engraving, (c) mold shaping, (d) wax application, (e) clay application, (six) dewaxing, (e) casting, (eight) finishing, (nine) coloring, and (ten) polishing. Among them, wax application and lost wax method are the main characteristics of Suzhou imitation bronze production techniques. Suzhou imitation antique bronze wares are exquisitely decorated, finely crafted, lifelike in color, and clear in layers. They are almost indistinguishable from the original in terms of shape, decoration, inscriptions, thickness, weight, homogeneous composition, fine workmanship, skin color, and rust spots. The large pieces are majestic, and the small pieces are exquisite, with great historical and cultural value and artistic appreciation value.
