Microsamples collected on 27 major paintings by Old European Masters dating from the 14th to the late 19th centuries were analyzed using synchrotron-based X-ray diffraction. Two complementary analytical configurations were used at beamlines ID22 (high angle resolution) and ID21 (high lateral resolution), in order to highlight markers of the different grades of the lead white pigments (mixture of cerussite PbCO and hydrocerussite Pb(CO)(OH)). Rietveld analysis and crystalline phases mapping at the microscale revealed the composition and microstructure of the pigments, shedding light on the preparation recipes and pigment choices of the artists through History.
采用基于同步加速器的 X 射线衍射技术,对来自 14 世纪至 19 世纪后期的 27 幅欧洲老大师主要画作上采集的微样本进行了分析。在光束线 ID22(高角度分辨率)和 ID21(高横向分辨率)上使用了两种互补的分析配置,以突出不同等级的铅白颜料(碳酸铅 PbCO 和碱式碳酸铅 Pb(CO)(OH) 的混合物)的标记物。Rietveld 分析和微尺度上的晶体相映射揭示了颜料的组成和微观结构,通过历史揭示了艺术家们的准备配方和颜料选择。
