The long-necked bottle with net patterns and double ears in hexagonal shape of the Xixia is an unearthed cultural relic collected in Ningxia Museum, which can be described as a masterpiece. Because of the long underground age, there are many rusts on the surface. In this paper, the rust of the six-edged binaural long neck vase of the Xixia was analyzed by means of micro- Raman spectroscopy. The results show that the rusts of the six-edged binaural long neck vase of the Xixia are atacamite, paratacamite, malachite and chalcanthite. Atacamite and paratacamite are harmful rusts, which repeatedly corrode the bronzes, while malachite and chalcanthite belong to harmless rusts and can be retained. The detection analysis provides a scientific basis for making a reasonable repair plan.
