This paper presents the novel application of recently developed analytical techniques to the study of paint layers on sculptures that have been restored/repainted several times across centuries. Analyses were performed using portable XRF, μ-XRD and μ-Raman instruments. Other techniques, such as optical microscopy, SEM-EDX and μ-FTIR, were also used. Pigments and other materials including vermilion, minium, red lac, ivory black, lead white, barium white, zinc white (zincite), titanium white (rutile and anatase), lithopone, gold and brass were detected. Pigments from both ancient and modern times were found due to the different restorations/repaintings carried out. μ-Raman was very useful to characterise some pigments that were difficult to determine by μ-XRD. In some cases, pigments identification was only possible by combining results from the different analytical techniques used in this work. This work is the first article devoted to the study of sculpture cross-section samples using laboratory-made μ-XRD systems.
本文提出了将最新发展的分析技术应用于研究经过几个世纪多次修复/重新绘制的雕塑上的涂料层的新方法。使用便携式 XRF、μ-XRD 和 μ-Raman 仪器进行了分析。还使用了其他技术，如光学显微镜、SEM-EDX 和 μ-FTIR。检测到了包括朱砂、雌黄、红漆、象牙黑、铅白、钡白、锌白（锌矿）、钛白（金红石和锐钛矿）、立德粉、金和黄铜在内的颜料和其他材料。由于进行了不同的修复/重新绘制，发现了古代和现代的颜料。μ-Raman 非常有助于表征一些通过 μ-XRD 难以确定的颜料。在某些情况下，只有通过结合本文中使用的不同分析技术的结果，才能进行颜料鉴定。这项工作是第一篇专门研究使用实验室制造的 μ-XRD 系统的雕塑横截面样品的文章。
