Microanalysis of clay-based pigments in painted artworks by the means of Raman spectroscopy

Original language description

FT Raman spectroscopy and micro-Raman spectroscopy with lasers of three different wavelengths (1064 nm, 785nm and 532 nm) were used for analysis of reference samples of natural clay pigments including white clay minerals (kaolinite, illite, montmorillonite), green earths (glauconite and celadonite) and red earths (natural mixtures of white clay minerals with hematite). In addition, eight micro-samples obtained from historical paintings containing clay pigments in ground and colour layers have been examined. Powder X-ray diffraction and micro-diffraction were used as supplementary methods. It was found that laser operating at 1064nm provided the best quality Raman spectra for distinguishing different white clay minerals, but the spectra of green and redearths were affected by strong fluorescence caused by the presence of iron. Green earth minerals could be easily distinguished by 532 or 785nm excitation lasers, even in small concentrations in the paint layers. On the other hand, when a
