TL;DR: It is demonstrated that this spectral range - essentially devoid of absorption peaks of the common binder materials - can be well used for identification of inorganic pigments in paint samples thereby markedly extending the possibilities of pigment identification/confirmation by ATR-IR spectroscopy into the realm of pigments having no absorptions in the mid-IR region.

TL;DR: In this paper, Raman spectroscopy was used to characterize the original composition and decay products in the mortars and pigment layers, complemented with quantitative analysis of soluble salts and chemometric and chemical equilibrium calculations.

TL;DR: In this paper, the results of field Raman analyses assisted by a hand-held energy dispersive-X-ray fluorescence spectrometer were used to experimentally determine the composition of compounds present in the walls and wall paintings of two Pompeian houses, one with many luxurious decorative elements and a more modest building (Regio IX, Insula 3, House 5/24).

TL;DR: New methodology for characterisation of the nature of the main carotenoids and their distribution in brown stains or patinas of a deteriorated wall painting on the north wall of the atrium of Marcus Lucretius House (Pompeii, Italy) is proposed.

TL;DR: In this article, the results of field Raman analyses assisted by a hand-held energy dispersive X-ray fluorescence spectrometer are presented for the experimental determination of efflorescence from walls and wall paintings of two Pompeian houses, one with many luxurious decorative elements and a more modest building (Regio IX, Insula 3, House 5/24).
