Pit K0007, located at the northeast corner of the outer walls of the Mausoleum of the first Qin Emperor, was excavated in the year 2 000, and 46 life-sized bronze waterfowls were unearthed from this pit. According to the report on archaeological excavation, these bronze waterfowls suffered from various diseases because of their harsh burial environment, as well as natural and man-made damage to the pit. Bronze crane No.23 is particularly exquisite and vivid. In order to restore and conserve this precious artifact, we developed a scheme based on its preservation state, disease state and relevant documents. After several essential technical procedures of restoration such as gluing, cleaning, consolidation and pin-connection, the bronze crane finally achieved an ideal exhibition effect.
