Argentinean prehistoric pigments’ study by combined SEM/EDX and molecular spectroscopy

Raman spectroscopy of minerals and mineral pigments in archaeometry

“…Darchuk et al investigated pigment samples from the Carriqueo rock shelter (Rio Negro Province, Argentina) by SEM‐EDS, FTIR and Raman spectroscopy. The basic components were determined as yellow or red ochres.…”

Effect of gamma irradiation on Korean traditional multicolored paintwork

“…In the previous study, various methodologies were reported for characterization and structural studies of pigments such as X-ray fluorescence analysis (XRF), scanning electron microscopy with energy-dispersive X-ray detection (SEM-EDX), XRD, particle-induced X-ray emission (PIXE), Fourier transform infrared spectroscopy (FT-IR), and FT-Raman analysis (Desnica et al, 2008;De Nolf et al, 2006;Darchuk et al, 2010;Webera et al, 1998). In this study, gamma-irradiated pigments were analyzed using XRD.…”

Identification of pyroxene minerals used as black pigments in painted human bones excavated in Northern Patagonia by Raman spectroscopy and XRD

“…Most prehistoric paintings found in rock art sites, decorated archaeological ceramics and, as in this case, bone remains in ritual contexts, contain red and black pigments as the main colorants [4][5][6][7]. Physicochemical analyses have shown that, in their great majority, the red paints in these artifacts are based on Fe oxides/hydroxides, and that the black pigments are either carbon-based, such as charcoal, or Mn oxides/hydroxides [4][5][6][7][8][9][10][11][12][13][14][15].…”

Raman spectroscopy is a well established and powerful technique for the non-invasive identification of materials in cultural heritage objects.…”
