“…Developments toward handheld or portable spectrometers allow ATR-FTIR spectroscopy to be employed in field-based or in situ research, 151,188,189 whilst most of cultural heritage research using ATR-FTIR spectroscopy is still lab-based. External Reflection (ER) and Diffuse Reflection (DR) modes have been used in portable FTIR devices to investigate cultural heritage 151,190,191 in excavation or storage sites, exempting artefacts from relocating frequently. One of the main advantages of ER and DR modes is that they are non-contact acquisition modes, allowing for completely non-invasive studies of cultural heritage materials.…”

“…Aside from spectral distortions, ER and DR can only detect shallow surfaces of examined objects. 191 Therefore, the spectra acquired in ER and DR modes may not be representative of the whole objects, especially when the objects show an inherent chemical heterogeneity. Although ATR mode requires contact between the crystal and the sample, it can reach higher lateral resolution in FTIR experiments compared to ER and DR modes.…”

“…Fourier transform infrared spectroscopy and Raman vibrational spectroscopy also stand amidst the most frequently used techniques for mineral characterization and differentiation [2,8,13,48,49]. Along with handheld XRF analysis [50], these techniques are probably the most commonly used analytical tools in conservation science, as they offer a series of advantages such as: relatively low-cost, non-or minimalinvasiveness and an immediate response in terms of results [51]. Chemometrics, such as PCA, applied to different spectroscopic data, is a powerful analytical tool, widely used in recent years for discrimination analysis, including the classification of pigments [52,53].…”

Assessment of Easily Accessible Spectroscopic Techniques Coupled with Multivariate Analysis for the Qualitative Characterization and Differentiation of Earth Pigments of Various Provenance

Natural minerals and earths with coloring properties have been widely used as artistic pigments since prehistoric times. Despite being extensively studied, the complex chemistry of earth pigments is still unsatisfactory described with respect to their mineralogical and structural variability and origin. In this study, a large group of earth pigments from various geographical locations was investigated using easily accessible spectroscopic techniques and multivariate analysis with the aim to identify distinctive mineralogical and chemical characteristics of natural pigment sources. Portable X-ray fluorescence (p-XRF), Fourier transform infrared spectroscopy (FTIR) and fiberoptic Raman spectroscopy were used for the elemental, molecular and structural characterization of the investigated pigments. Diagnostic spectral features and chemical patterns (fingerprints) were identified and discussed with respect to their geological sources. Due to the occurrence of similar accompanying minerals, it was observed that the differentiation of red and yellow ochers is more challenging compared to green, brown and black pigments. However, for some of the investigated pigments, the presence of certain accessory minerals and/or of certain chemical patterns can have diagnostic value. Principal component analysis (PCA) of the FTIR and XRF data matrices showed promising results in terms of geological attribution, highlighting a promising tool for provenance research. The results of the study demonstrate the potential benefits of this rapid and nondestructive approach for the characterization and differentiation of earth pigments with similar hues coming from different geological sources.

“…A number of informative reviews on portable instrumentation that include applications to cultural heritage are available. [3][4][5][6][7] Laser-induced breakdown spectroscopy (LIBS) is one analytical technique increasing in use for archaeological and cultural heritage object analysis. 8 XRF spectrometry has certainly been the more commonplace choice for elemental analyses of these often-precious samples considering its nondestructive nature.…”

Handheld laser-induced breakdown spectroscopy (LIBS) was applied to two studies of archaeological material at excavation sites in the Orvieto (Umbria), Italy geographic region. The short analysis times and wide range of detectable elements, covering both metals and nonmetals, achievable via LIBS played a central role in successfully exploring research questions specific to the analyzed artifacts. For one study, associations among Roman terraced walls at the Coriglia excavation site were established through comparisons among lime mortar elemental compositions measured in situ. New conclusions regarding construction phases were achieved, and agreement between handheld LIBS and handheld X-ray fluorescence (XRF) spectrometry results was established. Secondly, Etruscan bucchero pottery was examined to explore relationships among fabric color (gray and black), excavation site (Cavità 254 and Crocifisso del Tufo), and elemental composition. Differences were found and are discussed as they relate to ceramic production and object purpose. Principal component analysis was applied for data analysis in both studies.
