“…Its use in archeology and cultural heritage is quite recent and mainly focused on the study of organic analytes. These research areas have well‐consolidated analytical procedures based on techniques such as micro‐Raman spectroscopy (MRS), X‐ray fluorescence (XRF) and Fourier transform infrared microspectroscopy (FTIR) in different configurations. Other noninvasive and non/microdestructive methods, for example, X‐ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES) and scanning electron microscopy with energy dispersive X‐ray analysis (SEM‐EDX) are usually employed as surface analysis techniques applied to cultural heritage goods.…”

Organic and inorganic compounds of a gilt and painted leather artifact were studied by the use of time-of-flight secondary ion mass spectrometry (ToF-SIMS) technique as part of an in-depth study of this peculiar painting technique. The object under investigation is an altar frontal, coming from the church of San Domenico in Orvieto, which can be dated to the mid-17th century. High mass resolution spectrometry was applied for the chemical characterization of organic materials contained in the gold varnish and paint layer. ToF-SIMS analyses performed on reference compounds and samples from the artifact proved the presence of indigo to depict blue and lead white to depict white areas and the use of an oil binder as resulted by the presence of indigotin, palmitic and stearic acids signals with their diacylglycerols, lead soaps, lead oxides and hydroxides. The analyses have also shown the presence of colophony in the gold varnish. ToF-SIMS results were agreed and integrated with those obtained by other analytical techniques.

“…Examples of both portable and stationary XRF systems used for in situ and ex situ studies are numerous and diverse in the literature. Some recent applications are for paintings, investigation of paintings and other cultural heritage objects along with complementary analytical techniques, a remote‐controlled system used for field investigation, and analysis of murals using confocal synchrotron micro‐XRF . The typical characteristics of a handheld XRF were also deemed appropriate for investigations of Ethiopian artifacts in the field.…”

Application of a portable XRF analyzer to investigate the medieval wall paintings of Yemrehanna Krestos Church, Ethiopia

Despite the large body of ancient Ethiopian works of art in the form of murals, icons, and illuminated manuscripts, the physicochemical examinations carried out on them are few. This study is an in situ investigation of the wall paintings in the early 12th century Yemrehanna Krestos Church, Ethiopia. Fast, onsite, nondestructive analysis of the painting materials was carried out using a portable X-ray energy fluorescence dispersive spectrometer. It is believed to be the first onsite technical examination of Ethiopian mural paintings. This work resulted in information about the painting materials and the existence of different painting programs. The analysis revealed that the main pigments were red and yellow ochre, minium, cinnabar, orpiment, gypsum, lead, and white and carbon black; those typically employed in medieval times with no indication of later conservation-restoration intervention. Correlation between concentration of elements and multivariate statistical analysis was used to identify the most probable compounds and to classify sets of pigments used in two painting programs. The portable X-ray energy dispersive fluorescence spectrometer analyzer is found valuable to guide the in situ analysis and assess potential sites for microsampling for further investigations with complementary analytical techniques. However, in this expedition, we were unable to collect sufficient microsamples to warrant adequate complementary analyses. Characterization and documentation of the materials of the church murals support art historical studies and eventually conservation intervention plans.

“…Nowadays, due to the benefit of the brightness of synchrotron radiation, minor pigment phases can be identified with synchrotron radiation equipment, whereas classical laboratory instruments may not be sensitive enough to detect them (Herrera et al. 2008, 2009).…”

Determination of Pigments and Binders in Pompeian Wall Paintings Using Synchrotron Radiation – High‐resolution X‐ray Powder Diffraction and Conventional Spectroscopy – Chromatography

The employment of synchrotron techniques complemented by conventional laboratory systems has allowed us to deepen and improve our knowledge of Roman wall painting procedures. The palette identified in wall paintings from Pompeii and Herculaneum from the second century BC includes goethite, hematite, cinnabar, glauconite, Egyptian blue, and other components such as calcite and aragonite. Proof of the use of organic binders is provided by FTIR and PY-GC/MS. Therefore, the possibility of the use of 'a secco' techniques cannot be ruled out. Pigments in wall paintings are usually found in small percentages and conventional X-ray diffractometers do not detect them. Synchrotron radiation -high-resolution X-ray powder diffraction has allowed identification with only a few micrograms of sample.a rcm_478 286..307
