“…Analysis by proton induced X-ray emission (PIXE) [10,11], low vacuum-scanning electron microscopy (LV-SEM) [6,7] and micro-Raman spectroscopy (MRS) [8,9,12,13] have been applied for the analysis of paintings. Pigments [4][5][6]12], binding media and varnishes [13,14] were identified with different aims: to reconstruct the palette of a particular artist or to obtain historical information on the relationship between populations, trade and migration of cultural groups.…”

The investigation of unmatched ancient objects is an attentive and arduous activity to conservation scientists. An important aspect of art analysis is the question on sampling and avoiding damage on the artefact during the study. A possible way to maximize the information that is extracted from the historical object is using several sensitive micro-analytical techniques on the same micro samples. As an illustration of this multi-method approach, in this work, a canvas painting 'Virgin of Sorrows' was studied and its materials were analysed in order to roughly date and to authenticate this object of art. Proton induced X-ray emission (PIXE), neutron activation analysis (NAA), optical microscopy, scanning electron microscopy (SEM), micro-Raman spectroscopy (MRS) and Fourier transform infrared spectroscopy (FT-IR) were used, obtaining successful results. These methods allowed identifying the different inorganic pigments (iron oxide, carbon black, white lead, Prussian blue) as well as indigo. Optical microscopy and SEM revealed the layered structure of the samples, while FT-IR enabled to determine the nature of the varnish used (shellac). By using these complementary techniques, it was possible to identify the materials in the painting, which are indicative for the period of manufacturing the artwork.

Raman spectroscopy pigments on decorated antique Chilean pottery belonging to the Diaguita`s culture deposited in Museum of Limarí, have been studied by using Raman spectroscopy. Four ceramic fragments from the unknown contexts were examined. Four colors were found with certainty: red, black, brown and white. Quartz and manganese (kempite) salts, as well as different types of oxide pigments: hematite, tenorite and possibly goethite, were identified.

“…Bands at 343, 632 and 1224 cm −1 belonging to copper oxide (II) or tenorite [32] were identified in deep black dashes of the samples [see Additional file 1]. Copper was already reported in the black pigments of PreColumbian Chilean potteries [43]. The copper content of the black color appears to be a particularity of Diaguitas; in fact, in other cultures of South America the black pigment contains iron, manganese and carbon [44][45][46][47] in their composition.…”

Background: Natural and synthetic colouring products along with its associated supporting materials have been studied in several expressions of the Chilean cultural heritage using vibrational spectroscopy. These expressions include archaeological remains as well as works of art. Results: Among the materials studied so far we can count pigments found in archaeological sites from the north of Chile, in plaster (wall paintings) and in polychrome (beams), and dyes mainly related to added components on historic silk textiles. Identification of materials resulted to be relevant to know about Chilean culture through history. Conclusions: The vibrational knowledge obtained contributes to give solid data as a complement to the different information aspects collected by conservation professionals involved in the characterization and conservation procedures of cultural heritage and also it gives us the opportunity to share knowledge and to give value to objects that not always are of the public domain.
