“…The laser beam was focused on a diameter of about 25, 5 and 1.5-2 μm respectively. The Raman probe was coupled with an Andor monochromator (Shamrock 163 with a 100 μm entrance slit), and a Newton DU 971P-BV camera from Andor was used as the detector for the Raman signals, working at À 60 1C [11][12][13].…”

“…The spectral resolution of the Raman spectrometers was $ 4 cm À 1 when using the 600 groves' grating and $ 2 cm À 1 when using the 1200 groves' grating. All Raman spectra were recorded at least 5 times for each sample in different locations, and all spectra presented in this paper were representative [11][12][13][14].…”

“…The chemical composition of ceramic glazes and pastes was also accurately determined by X-ray fluorescence with the use of a Niton XL3T GOLDD from Thermo Scientific spectrometer with X-ray generator of 50 kV/200 μA, equipped with a CCD for image location (3 mm spot diameter) and storage [11][12][13].…”

“…Plots of ν max versus the wavenumber maximum (δ max ) of bending Si-O multiplets [22,23] allows one to identify glass types such as lead-based compositions soda, potash-based, mixed potash or soda-lime. X-ray diffraction analysis (XRD) is also a very important technique that may provide complementary information to micro-Raman spectroscopy for the characterization of pottery [11,24,25], and is especially useful for the study of the crystalline phases of ceramic pastes. In many cases pastes from clay minerals exhibit weak or complex Raman signals, and XRD may provide useful information concerning the detailed mineralogical composition of a ceramic body by using a diffraction pattern database [11].…”

Minerals, as raw structural materials or pigments, play a fundamental role in archaeometry, for the understanding of nature, structure and status of an artefact or object of interest for cultural heritage. A detailed knowledge of the mineral phases is crucial to solve archaeological problems: Raman spectroscopy is a powerful investigation technique and has been applied extensively in the last 30 years on mineral identification and on pigment degradation. Here we report an updated review, covering the last decade, of the applications of Raman techniques to issues in which raw minerals, including mineral pigments, are involved. Particular attention is devoted to cases where the Raman analysis of minerals is deeper than a simple identification of the phases present in an archaeological or artistic object.

A detailed archaeometric study of a Late Neolithic cup found in the São Paulo Cave, Almada, Portugal, has been made, which, according to its unique decorative characteristics, may have had a ceremonial and symbolic utilization. Other 23 sherds, collected around the cup, dated early and late Chalcolithic periods, have also been studied. The conjugation of the information provided by the Raman, X‐ray diffraction, and X‐ray fluorescence emission experiments for the locally collected cup, sherds, and clays, with emphasis on the analysis of the ceramic bodies, allowed the characterization of the artefacts. In the reddish, brownish, or black parts of the surface of the cup, haematite, magnetite, and carbon black pigments were identified, whereas in the whitish parts, quartz was the most common mineral. Three main groups could be identified in the ceramic bodies, although all were made with the use of locally collected clays. In the first group, where the Neolithic cup is included, the potters used Miocene clays, most probably from the Palença clay sources, which were fired at a high temperature of about 950°C. The second group was also produced with raw materials of Miocene origin but the firing temperature was much lower, around 800°C, as revealed by the existing amount of muscovite. The third group, with clays of a Pliocene origin, exhibited a much lower content of calcium carbonate, as evaluated by the R index ([SiO2 + Al2O3 + K2O]/CaO), considered as ceramic raw material or a geological source indicator. These clays contain high amounts of kaolinite, muscovite, quartz, microcline, and anatase.
