“…In all spectra the Pb was characterized as a majority element, being the presence of this element due to by the use of pigments with Pb, such as lead white (2PbCO 3 .Pb(OH) 2 ), yellow massicot (PbO) and red litharge (PbO). These pigments are also known for their secant properties from Pb, so by the end of the 19th century they were commonly used as the layer of preparation for polychromy in artworks [6,14,15].

Analysis of historical artifacts, it's a multidisciplinary field of research known as archaeometry, has expanded greatly in recent years. One of the reasons for this expansion was the great effort of physicists and engineers, who focused on the development of portable instruments, that allow analyses in situ and non-destructive of these artifacts. The X-Ray Fluorescence (XRF) is techniques of the most used in this field of study. In this work the XRF was used to analysis the artwork "Passagem de Humaitá", by the Brazilian painter Victor Meirelles, dated 1872. The painting, which has dimensions of 268 cm x 405 cm, is exposed at National Historical Museum located in Rio de Janeiro. The analyses were carried out in situ with portable XRF system model TRACER IV from Bruker, which has Rh anode and can operate with maximum voltage and current of 40 kV and 200 μA. Spectra of more than 80 points of the painting were obtained, with the tube operating at voltage of 40 kV and a current of 10 μA, and the spectra were collected during 60 seconds. The results allowed to conclude that the painter used pigments such as vermilion and/or cinnabar [HgS], calcite [CaCO3], zinc white [ZnO], lead white [(PbCO3)2·Pb(OH)2], red ocher [Fe2O3], brown umbra [Fe2O3.MnO2].

“…O processo de fabricação das placas utilizou os mesmos parâmetros que usualmente são usados para a confecção da estrutura suporte do acetato As superfícies das placas sem e com selante, nas diversas composições testadas, foram observadas por estéreo microscopia, microscopia óptica (MO) 12,13 e por eletrônica de varredura (MEV) 12,14 , respectivamente através dos microscópios Olympus modelo 8ZX16, Zeiss modelo M2m e Hitachi modelo TM3000, este último operando a 15kV. Análise e mapeamento dos elementos químicos [15][16][17][18] presentes foi realizada por espectroscopia por dispersão de energia (Energy Dispersive Spectroscopy -EDS) [19][20][21][22][23] utilizando-se um detector X Flash MIN SVE fabricado pela Bruker acoplado ao MEV.…”

“…Policromias em madeira vem sendo analisadas por pesquisadores sul americanos na tentativa de compreender as técnicas e materiais empregados no período colonial FREITAS et al, 2016). Da mesma forma, pinturas sobre tela, madeira ou metal são estudadas com diferentes perspectivas, como a caracterização de materiais e técnicas (DE OLIVEIRA et al, 1998;HALAC et al, 2012;MARTE et al, 2014;BADILLO-SANCHEZA e BAUMANN, 2016;RODRI-GUEZ-GACITUA et al, 2016;TOMASINI et al, 2016) assim como sua degradação, levando à formação de eflorescência em sua superfície (PUGLIERI et al, 2016).…”

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.
