As últimas décadas tem presenciado um crescente aumento no uso de métodos físico-químicos de análise de bens culturais. Algumas dessas técnicas tem se mostrado particularmente úteis pelo caráter não invasivo e não destrutivo que apresentam e, dentre elas, a espectroscopia Raman apresenta posição de destaque. Neste artigo, essas características da técnica são detalhadas, bem como são apresentados os fundamentos teóricos do espalhamento inelástico de luz e discutidos alguns aspectos práticos de sua utilização. Finalmente, é apresentado um levantamento detalhado dos grupos de pesquisa da América do Sul, voltados ao estudo de bens culturais, que tem se utilizado dessa ferramenta analítica e em qual tipo de questionamentos vem sendo aplicada. Abstract: The last decades have witnessed an ever growing increase in the usage of physico-chemical methods to investigate cultural heritage problems. Some of these techniques are proving to be particularly useful in such a context, due to their non-invasive and non-destructive nature; among them, Raman spectroscopy occupies a prominent position. In this paper, such characteristics of the technique are detailed and the physical basis of inelastic light scattering are presented, together with some practical aspects of its applications. Finally, it is here offered a detailed survey in the literature on the South American research groups devoted to the investigation of cultural heritage issues who are using Raman spectroscopy, and the type of interrogation carried on.

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.

“…On Andean easel and wall paintings from colonial times, the predominant variety has generally been found to be lead white, consisting of basic lead carbonate (2PbCO 3 ·Pb(OH) 2 ) often mixed with neutral lead carbonate (PbCO 3 ) [23], while published analyses of occurrences on Inka and pre-Inka painted surfaces most often describe calcium-based minerals, such as calcite, gypsum and apatite [25][26][27][28]. Occasional instances of early white pigments bearing Ti and/or Si have been reported, most often as clay-based minerals with quartz and/or titanium dioxide as minor constituents [25,26,29,30]. On the qeros that we have studied and that can be stylistically dated to colonial times, we have found the white pigment to be exclusively lead white.…”

The occurrence of a titanium dioxide/silica white pigment on wooden Andean qeros: a cultural and chronological marker

A white pigment found on a sub-set of polychromed wooden Andean ritual drinking cups called qeros has been characterized by X-ray diffraction, X-ray fluorescence spectroscopy and Raman spectroscopy as consisting principally of cristobalite (SiO 2 ), anatase (TiO 2 ), and α-quartz (SiO 2 ). This unexpected assemblage of minerals is like that reportedly found in an exposed titanium ore body in southern Peru, an area once part of the Inka Empire. The ore is a close match in color and composition to the white pigment found on the qeros and offers a possible candidate for the geological source of this material. The temporal horizon for the use of this pigment appears to be ca. 1532-1570, correlating with what we refer to here as the Transitional Inka/Early Colonial period, although production of polychromed qeros may have begun before this time and certainly continued well into the eighteenth century or later. Not long after the arrival of the Spanish, this titanium dioxide/silica pigment was replaced by lead white, a result of Spanish influence. We suggest that white pigments on qeros offer material evidence for establishing a chronology for these ritual vessels and that the titanium dioxide/silica pigment on this group of qeros constitutes a previously unidentified, naturally occurring white pigment indigenous to the southern Andes, the first use of which probably dates to the PreColumbian period.
