“…Moreover, some archaeological samples were also analyzed using high-resolution synchrotron X-ray diffraction analyses performed at the ID22 beamline of the European Synchrotron Radiation Facility (ESRF, Grenoble, France), thanks to the Historical Materials "Block Allocation Group"(BAG) access [15,16]. In the context of the BAG, standardized operating conditions were provided, and the synchrotron X-ray diffraction data were recorded at a wavelength of λ = 0.3542 Å, corresponding to an incident radiation of 35 keV.…”

In this study, the well-preserved glazes of 13 colored bricks representative of the decoration of the palaces of Sargon II (Khorsabad, 8th century BC) and of Darius I (Susa, 6th century BC) were examined. The purpose of this research is to gather information about the ancient brick manufacturing processes by examining the colored glazes and, in particular, black glazes using a combination of methods that included optical microscopy, SEM-EDX, synchrotron µ-XRD, and µ-Raman spectroscopy. The results revealed different coloring techniques for producing black glazes in the Neo-Assyrian and Persian Achaemenid periods. Regarding the black glazes of Susa, it is particularly interesting to note that their chemical composition varies according to the function of the glazes on the bricks: manganese oxide (for colored fields of glaze) and iron-rich compounds (for raised lines separating glazed areas). In comparison, the black glazes from Khorsabad are characterized by the presence of spherical copper sulfide and galena nanoparticles (ranging from less than 100 nm to about 1 µm) for both the glazed areas and the separating lines. This coloring technique to obtain black glazes is very rarely described in the literature, as well as the mechanism of formation of these spherical nanoparticles.

“…Micro X-ray Fluorescence (µXRF) and X-ray Absorption Near Edge Structure (µXANES) High lateral resolution information on the distribution and speciation of S of samples A7, A9, A5, A4 and A12 was obtained by performing hyperspectral 2D µXRF mapping and µXANES spectroscopy analysis in XRF mode at S K-edge at the scanning X-ray microscope end-station hosted at the beamline ID21 [24,25] of the ESRF (Grenoble, France). The energy calibration was performed using reference powders of CaSO 4 ⋅2H 2 O.…”

The deterioration of cadmium yellow paints in artworks by Joan Miró (1893–1983) and from painting materials from his studios in Mallorca (Spain) was investigated for the first time. Artworks showed discolouration and chalking of paints containing cadmium yellow, altering the colour balance of the works. Analysis of samples from these artworks and from tube paints and palettes containing degraded and non-degraded cadmium yellow paints showed that degraded paints are composed of poorly crystalline CdS/Cd1 − xZnxS with a low percentage of Zn in an oil binding medium. Cadmium sulfates were identified as the main deterioration products and their distribution in the paint layers was mapped using SR µXANES and µXRD techniques. Time-resolved photoluminescence measurements demonstrated that highly degraded samples display a peculiar pink/orange emission with microsecond lifetime. In agreement with recent studies on altered cadmium paints, these evidences suggest that the cause of the chemical change of the paint should be related with its manufacturing method, which affects the degree of crystallinity of the resulting pigment and includes the presence of zinc, besides the environmental conditions in which artworks have been exposed. Finally, it is worth noting that the degraded paints in the analysed Miró artworks have a chemical composition very similar to the one of the paint in the tube Cadmium Yellow Lemon No. 1 by Lucien Lefebvre-Foinet. Indeed, paint tubes of this brand were found in the studio, linking the use of this product with Miro’s degraded artworks.

“…However, these techniques may face challenges in distinguishing the newly formed phases within the microstructure due to overlapping vibrational bands. More recently, synchrotron radiation (SR) facilities have experienced a remarkable rise in the study of Cultural Heritage materials [20][21][22][23]. Advanced radiation imaging techniques, such as SR-based X-ray micro-computed tomography (µ-CT), have been employed to non-invasively determine the effects of the new product crystallization on the 3D stone's microstructure at a maximum voxel size of 1 µm 3 .…”

Understanding the effects of consolidating inorganic mineral treatments on carbonate stones of cultural heritage, on the nature and distribution of newly formed products within the matrix, poses a significant challenge in Heritage Science and Conservation Science. Existing analytical methods often fail to deliver spatial and compositional insights into the newly formed crystalline phases with the appropriate high lateral resolution. In this study, we explore the capabilities and limitations of synchrotron radiation (SR) micro-X-ray powder diffraction (µXRPD) mapping combined with micro-X-ray fluorescence (µXRF) to give insight into compounds formed following the application of ammonium oxalate (AmOx) and diammonium phosphate-based (DAP) solutions on porous carbonate stone. Ultimately, the integration of µXRPD mapping and µXRF analysis proved itself a powerful asset in providing precise qualitative and quantitative data on the newly formed phases, in the case of both calcium oxalates (CaOxs) and calcium phosphates (CaPs), and their complex stratigraphic distribution, thus opening a new route for applications to a more comprehensive study of inorganic treatments applied to carbonate substrates.
