Abstract：The restoration of Chinese bronzes has a long history and tradition, and is characterized by its own system. Recently, the modern western restoration technologies for culture relics from Europe become to be introduced into China, which are different from the traditional Chinese restoration method. There is much to be studied. Make a foundry part and solder it on the bronze for the missed part is the traditional way of restoration for an incomplete ancient bronze. This method would cause a new damage in the culture relics, and the soldering acid contains Cl-, which is harmful to the conservation of ancient bronze These two aspects do not conform with the conservation principle of culture relics. On the other hand, make a resin fitting and stick it on the bronze is a modern western way of restoration for an incomplete ancient bronze. This method conforms with the conservation principle of culture relics, but the resin fitting is easily destroyed and it is not durable. In this paper, based on the essential principle of conservation of cultural relics, a new type of restoration method for incomplete bronze Yong Zhong is developed by improving the available restoration technology, which takes advantage of the lost-wax method to implement the making and installing of the fitting at the same time. The results of this new restoration technology show that this method can replace the traditional one, to have a satisfactory effect.
