摘要
为了对出土于敦煌佛爷庙湾的一件魏晋时期的铜镜进行保护研究,对其病害特征进行了描述,并对其锈蚀产物进行了检测分析。首先绘制了这件铜镜的病害图;采用湿法化学分析、便携式X荧光光谱仪(XRF)、X射线探伤仪、激光共焦显微拉曼光谱仪(RAMAN)、多晶X射线衍射仪(XRD)和同步热分析仪(TG-DSC)等方法,对铜镜的材质、纹饰及主要锈蚀产物进行了定性分析检测检测结果表明,该铜镜的材质为铜锡铅三元合金;镜背覆盖着精美的龙纹;铜镜的锈蚀产物中都含有碱式氯化铜。
In order to conserve a bronze mirror from Wei and Jin Dynasties unearthed at the Fo - Ye Temple in Dunhuang,the decay and damage characteristic of the mirror were described and the main corrosion products were analyzed.First,a picture showing the decay and damage of the object was drawn.Then the composition of the material in the mirror and the mirrors decoration and its main corrosion sites were analyzed by qualitative analysis of wet on bronze mirror,X-ray fluorescence,X -ray inspection,Raman spectroscopy,X-ray diffraction and differential scanning calorimetry The results showed that the bronze mirror was an alloy of bronze,containing both tin and lead;the back of the bronze mirror was found to be covered with an exquisite dragon pattern;the corrosion products of bronze mirror contained copper chloride.These results were used to develop a scientific conservation plan.
