Description
Synchrotron-based X-ray Powder Diffraction (SR-XRPD) is particularly suited for the study of historical pigments. This technique indeed enables to discriminate between the multiple inorganic products present in complex paint stratigraphies at the micrometric scale, but also to provide detailed information on their composition and microstructure. This talk will present SR-XRPD research conducted via complementary analytical configurations, aimed at revealing the ancient syntheses of inorganic pigments, and deciphering the potential alteration mechanisms active in historical pictorial formulations. The communication will also present the “Heritage Materials” BAG implemented at the ESRF, and the opportunities offered by such collaborative initiatives to the Heritage community.
