“…For the identification of inorganic pigments vibrational spectroscopic techniques are mostly employed [49]. Raman spectroscopy and more specifically Raman microscopy have been established to be highly effective in artwork diagnosis [50][51][52][53][54][55][56][57][58][59][60]. Characterization of both inorganic and organic materials in paint samples is further aided by Fourier transform-infrared (FTIR) spectroscopy but the scope of this technique is limited by scattering of the IR light within the sample [61].…”

“…3 For these reasons, the prevailing view is that the presence of anatase as a white pigment on archaeological artefacts or early paintings should be regarded as a clear-cut indicator of modern intervention in some form or another. 4 As part of a programme to investigate the procurement of paint pigments and other raw materials in Roman Britain, 5,6 Raman spectroscopy has been used to identify pigments on several samples of ceramic vessels which appear to have been used as paint pots. Surprisingly, evidence has been found for the presence of anatase in the white pigment.…”

Analysis of a sample of white paint from a ceramic pot of Roman date, using FT-Raman spectroscopy indicated that a component of the white paint was anatase. This suggested that the presence of anatase, usually regarded as an indicator of modern (early twentieth century or later) intervention, could extend back at least two thousand years. Further examination of the sample, using scanning electron microscopy, chemical analysis using an energy-dispersive X-ray analyser, X-ray diffraction and microRaman spectroscopy, has confirmed the presence of anatase in small proportions (approximately 1.5%). An explanation for the initial observations relating to the sensitivity of anatase detection in Raman analysis is explored.

“…The structure suggests a practice of smoothing the coarse undulations of the basal wall material with coarse stucco and then creating a smooth painting surface with a finer more highly ground material. This is a similar practice to that employed by the Romans and later Europeans (Damiani et al, 2003;Edwards et al, 2002Edwards et al, , 2003b.…”

“…While it has been used to identify pigments on rock art (Edwards et al, 1999;Mortimore et al, 2004), frescos (Bikiaris et al, 1999;Edwards et al, 2002Edwards et al, , 2003b and painted pottery (de Waal, 2004), little work has been focused on Maya stucco and pigments. Some early petrographic and X-ray diffraction analysis determined the composition of the stucco and mortar for different Maya sites (Hansen et al, 1997;Huenda-Tanabe et al, 2004;Littmann, 1958).…”

Micro-Raman spectroscopy has been applied to painted stucco samples from three buildings at the Maya site of Copan, Honduras. The buildings, Clavel (AD 450e550), Ani (AD550e650) and Structure 10L-22 (AD730,) date from three phases of the Classic Period (AD400e820) acropolis construction. The red pigment has been identified as haematite and the stucco as a mixture of calcite particles dispersed throughout a calcite based lime wash stucco. The physical structure of the stucco changed through time, indicating a refining of production techniques over this period. By combining Micro-Raman spectroscopy with other micro-ATR infrared spectroscopy and environmental scanning electron microscopy a detailed investigation of the materials and production techniques used to decorate these buildings has been made. Differences in the mineralogy of the red pigment used on each building indicate a different geological pigment source for each period.
