The process of investigating paintings includes the identification of materials to solve technical and historical art questions, to aid in the deduction of the original appearance, and in the establishment of the chemical and physical conditions for adequate restoration and conservation. In particular, we have focused on the identification of several samples taken from six famous canvases painted by Pedro Atanasio Bocanegra, who created a very special collection depicting the life of San Ignacio, which is located in the church of San Justo y Pastor of Granada, Spain. The characterization of the inorganic and organic compounds of the textiles, preparation layers, and pictorial layers have been carried out using an XRD diffractometer, SEM observations, EDX spectrometry, FT-IR spectrometry (both in reflection and transmission mode), pyrolysis/gas chromatography/mass spectrometry and synchrotron-based micro-X-ray techniques. In this work, the advantages over conventional X-ray diffraction of using combined synchrotron-based micro-X-ray diffraction and micro-X-ray fluorescence in the identification of multi-layer paintings is demonstrated.
绘画作品的调查过程包括对材料的鉴定，以解决技术和历史艺术问题，帮助推断原作的外观，并为充分修复和保护建立化学和物理条件。特别是，我们专注于从西班牙格拉纳达的圣胡斯托和牧师教堂里的圣伊格纳西奥的六幅著名画布上的六个样本的鉴定，这些画布由佩德罗·阿塔纳西奥·博卡涅格拉绘制，他创作了一个非常特别的系列，描绘了圣伊格纳西奥的生活。使用 X 射线衍射仪、SEM 观察、EDX 光谱仪、FT-IR 光谱（反射和透射模式）、热解/气相色谱/质谱和基于同步加速器的微 X 射线技术对纺织品、制备层和绘画层的无机和有机化合物进行了表征。在这项工作中，展示了在鉴定多层绘画作品中，结合基于同步加速器的微 X 射线衍射和微 X 射线荧光的优势，优于传统 X 射线衍射。
