“…Therefore, the identification of the organic materials in pictorial layer is realized with micro‐destructive methods as Fourier transform infrared (FTIR) spectroscopy, which, besides other analytical methods as stratigraphy, microscopy and analysis of the images obtained with different types of light sources, provides reliable and detailed information about the analyzed painted surfaces. Recent studies realized in this regard on a variety of painted supports confirm the necessity of these methods …”

An analytical protocol consisting of X-ray fluorescence spectroscopy, optical microscopy and Fourier transform infrared spectroscopy was used to study the origin and the nature of the materials (pigments, binders and coating preparation) of the Fundenii Doamnei church mural paint from Bucharest. The main interest of the present study consisted in the original votive paint from narthex, painted in 1757 in a secco technique.During analysis, an unexpected pigment in the votive paint could be detected by the combined analytical techniques: ultramarine blue. Along with this pigment, the presence of gypsum binder based on egg and flax seed oil could also be evidenced. These results demonstrated a secco execution technique of the votive paint and also the presence of a restoration treatment. Moreover, during the present study, the components of the preparation layer and the constitutive pigments from both 1699 and 1757 years mural paints have been analyzed. Hence, the following pigments could be identified: vermilion, azurite, cinnabar, lead white, ochre, natural umber and gold, by using the combination of the analytical techniques.The novelty of our results consists in detecting the composition of the materials used in this church painting (fresco and a secco) during these 254 years since its first restoration.The results of these investigations pointed to the suitability of the non-destructive and semi-destructive analytical techniques in the complex characterization of the paints realized in different techniques, at different periods.

“…Several techniques can be exploited for this aim, such as atomic emission spectroscopy, proton‐induced X‐ray emission, inductively coupled plasma, neutron activation analysis, and Raman and infrared spectroscopy . Also X‐ray fluorescence (XRF) has been used, mostly on ground ceramics, representative of the whole object . Thanks to the development of portable XRF, this technique is particularly suitable to detect the chemical elements of archaeological unmovable objects.…”

Application of X‐ray fluorescence spectroscopy to provenance studies of Algerian archaeological pottery

The North African regions boast a multimillenary tradition of pottery production that represents a decisive progress in all societies. In this paper, we present the analysis of several fragments of pottery dating from the Middle Ages and collected in the archaeological site of Gouraya in Béjaïa (Algeria). Energy‐dispersive X‐ray fluorescence measurements were performed to obtain the elemental composition of the clays and to attempt a classification of the samples through multivariate analysis methods, connecting them to the archaeological information about the sites. Hierarchical clusters analysis (HCA) identified two possible different groups, related to different production sites, even if only one source of clay seem to be used, consistently with the geological contest. Based on the results, a tentative provenance interpretation could be proposed on historical bases. We put in place a strategy that made it possible to perform provenance studies respecting sample integrity as we aim to extend our research also to integer and well‐preserved object from museum, to create a database for Algerian production of in the Middle Ages.

Comparison between XRF, TXRF, and PXRF analyses for provenance classification of archaeological bricks

et al. 2013

Ceramics provenance studies based on minor and trace elements are widely used to help in gathering knowledge of local furnace presence and commercial trades. Most of the times, destructive analyses are allowed because of the high amount of material, but sometimes (integer vessels, architectural decorations, etc.), a nondestructive examination is required. In both cases, X-ray fluorescence (XRF) analysis can be a useful tool.In this work, we compare the classification results obtained on a set of bricks from the medieval Chartusian monastery Certosa di Pavia in the Po valley, northern Italy, exploiting XRF, portable XRF, and total reflection XRF (TXRF) spectrometers.The XRF nondestructive analyses were performed both in situ before sampling and in the laboratory without preparing the shards. Grounded samples were instead used to obtain semi-quantitative TXRF analysis without dissolving the samples but using a suspension in high-purified water. The project aimed at verifying if a correct classification was possible even if a quantitative determination of minor and trace elements is abandoned, allowing a faster response when a large amount of data is concerned. For this reason, weight concentration was determined from laboratory XRF measurements only, whereas semiquantitative results and entire spectra were considered for TXRF and the in situ campaign, respectively. Data were then submitted to different statistical data treatments to obtain provenance classification.
