“…Each one of these techniques has its own place in the cultural heritage field, and they are often used together in order to overcome specific limits. The synergic application of analytical techniques, exploiting different radiation frequency ranges, indeed allows for obtaining complementary information for a complete picture of the palette [2][3][4][5], main alteration products [6][7][8][9] and organic substances [10][11][12][13][14]. Despite the poor conservation state of the decorative materials and the presence of several retouched and restored areas, the analytical approach adopted here provided very informative results, not only for the identification of original materials but also for the identification of modern compounds, allowing the individuation of restored areas that can be confirmed and highlighted by results obtained by imaging results [15].…”

Identifying Original and Restoration Materials through Spectroscopic Analyses on Saturnino Gatti Mural Paintings: How Far a Noninvasive Approach Can Go

This paper presents the results obtained for the mural paintings (XV century CE) in the church of San Panfilo in Villagrande di Tornimparte (AQ, Italy) by means of noninvasive spectroscopic techniques; this research is a part of the project on the Saturnino Gatti pictorial cycle, promoted and coordinated by the AIAr (the Italian Archaeometry Association). Digital optical microscopy (OM), X-ray fluorescence spectroscopy (XRF), fiber optics reflectance spectroscopy in the UV–Vis–NIR range (FORS), Fourier transform infrared spectroscopy in the external reflection mode (ER-FTIR), and Raman spectroscopy were performed on the points selected based on the image analysis results and the few available records on previous intervention, with the aim of characterizing both the original and restoration organic and inorganic materials. The synergic application of complementary techniques allowed us to obtain a complete picture of the palette and the main alteration products and organic substances (of rather ubiquitous lipid materials and less widespread resin and proteinaceous materials in specific points). The identification of modern compounds permitted the individuation of restoration areas; this was confirmed by the comparison with multiband imaging results, as in the case of specific green and blue pigments, strictly related to the presence of high signals of zinc. This analytical protocol left only very few ambiguities and allowed to minimizing the number of samples taken to clarifying, by sample laboratory analyses, the few doubts still open.

“…In addition, the availability of the original materials used for their creation in artists’ studios can be a valuable help to facilitate compositional analysis [ 30 ]. Further advantage of studying contemporary art materials is that often the artists, or their assistants, are alive and can contribute to documenting the materials through interviews [ 28 , 30 , 31 , 32 , 33 ]. In parallel, to clarify the materials and fabrication methods of contemporary art, a few museum research programs collaborate with artists to create databases of materials.…”

This review is conceived as a guide for material science researchers and conservators aiming to face the problem of deterioration of contemporary artworks entirely or partially made of plastics. It initially illustrates the analytical approaches for identifying polymeric material components in 3D art objects, such as sculptures and installations, and provides a perspective of their limits and advantages. Subsequently, the methodologies used for studying the deterioration of contemporary art plastics are reviewed, emphasising the main effects of the different types of degradation (i.e., migration of additives, oxidation and hydrolysis) and suggesting the appropriate techniques for their detection. Finally, the application of artificial ageing tests is critically assessed. All the concepts are elaborated through case studies and examples.

Botteon et al evaluated the use of portable micro-spatially offset Raman spectroscopy (micro- SORS) to analyze pieces of artwork from the 16th century [ 84 ].…”
