“…The depth dependency is confirmed also by the elemental analysis, which clearly shows a surface enrichment of about 100 µm thickness (Figure 7b). The data obtained from the analysis are in agreement with the literature [35]. The data was taken and adapted from Ref.…”

Scientists, curators, historians and archaeologists are always looking for new techniques for the study of archaeological artefacts, especially if they are non-destructive. With most non-destructive investigations, it is challenging to measure beneath the surface. Among the vast board of techniques used for cultural heritage studies, it is difficult to find one able to give information about the bulk and the compositional variations, along with the depth. In addition, most other techniques have self-absorption issues (i.e., only surface sensitive) and limited sensitivity to low Z atoms. In recent years, more and more interest has been growing around large-scale facility-based techniques, thanks to the possibility of adding new and different insights to the study of material in a non-destructive way. Among them, muonic X-ray spectroscopy is a very powerful technique for material characterization. By using negative muons, scientists are able to perform elemental characterization and depth profile studies. In this work, we give an overview of the technique and review the latest applications in the field of cultural heritage.

“…Considering the results presented in this work and previous results [21,23,30], it can be concluded that the combination of XRF and GRT gives good results for bulk concentrations of coins if: (1) surface and bulk show different concentrations (there is an enrichment and/or corrosion of the surface of the coin) and (2) bulk is an approximately homogeneous mixture. However, further studies are needed to improve and optimize the method.…”

This work focuses on the analytical study of eight medieval metallic artefacts discovered during the archaeological excavations of the Ereñozar necropolis (13th century, Basque Country, Spain). As the conservation state of archaeological objects is closely related to the characteristics of the burial environment, chromatographic analysis was performed with the aim of quantifying the soluble salt content of the burial ground. Moreover, portable systems were used for the elemental and molecular characterization of the artefact collection. A hand‐held X‐ray fluorescence spectrometer was used to analyse the alloys constituting the objects. Then, the characterization of the main corrosion phases affecting the artefacts was carried out using two portable Raman systems. Both tools, equipped with different excitation lasers (785 and 532 nm respectively), were used in a complementary way by coupling them with the BAC151B video microscope. Thanks to its dual laser wavelength port, it was possible to sequentially focus with both lasers on the same selected spot. In this way, the sensitivity of each system for the characterization of Fe‐based and Cu‐based corrosion phases was also compared. Furthermore, the information obtained from both chromatographic and spectroscopic techniques allows the modelling of the chemical reactions that led to the formation of the identified degradation products.
