Additional file 1 of Close up to the surface: reflections on a preliminary forensic study of four Chinese bronze mirrors

Additional file 1: Table S1. Elemental abundances for both the reflective and knob side surfaces of the 4 mirrors as provided by X-ray fluorescence measurements. Note the trace mercury found on mirrors 3 and 4 and the Chromium found on mirrors 1 and 2 from ancient and modern treatments respectively.附加文件1：表S1。本表格提供了经X射线荧光（X-ray fluorescence）测量得到的4块反射镜的反射面与旋钮侧表面的元素丰度数据。请注意：3号与4号反射镜上检出痕量汞，而1号与2号反射镜上的铬分别源自古代与现代的表面处理工艺。
