“…No Brasil, a arqueometria é uma técnica ainda em franca expansão. Suas aplicações são principalmente baseadas no uso de equipamentos portáteis, como microfluorescência de raios X e microespectroscopia Raman, mas também já estão sendo usadas técnicas analíticas quantitativas laboratoriais, como espectroscopia de infravermelho por transformada de Fourier e microtomografia computadorizada (Alves et al 2014;Appoloni 2013;Appoloni, Parreira, and Lopes 2008;Puglieri et al 2019;Ribeiro et al 2015;Santos et al 2009;Silva et al 2004).…”

Este artigo apresenta uma revisão sobre os principais métodos analíticos atualmente empregados no estudo de bens culturais e arqueológicos, com especial foco em técnicas baseadas em sincrotron, explorando suas vantagens e limitações dentro das demandas desse campo. As técnicas abordadas são a tomografia de raios X para análises de imagem do interior de objetos, a fluorescência de raios X para o mapeamento químico da superfície dos objetos de interesse, e a absorção de raios X para a especiação química de determinados elementos. Tais técnicas encontram-se disponíveis na fonte de luz sincrotron brasileira do Laboratório Nacional de Luz Síncrotron, o qual atualmente constrói Sirius, uma fonte de 4a geração que irá levar o Brasil a novas fronteiras tecnológicas para estudos de materiais, tal qual na área arqueometria. Abstract: This article presents a review about the main analytical methods currently applied in the study of cultural heritage and archeology, with a special focus on synchrotron-based techniques, exploring the advantages and limitations within the requirements of the field. The techniques presented are X-ray tomography for imaging the interior of objects, X- ray fluorescence for chemical mapping of the surface of objects of interest and X-ray absorption for chemical speciation of elements. These techniques are available in the Brazilian synchrotron light source of the Brazilian Synchrotron Light Laboratory, which currently builds Sirius, a 4th generation source that will take Brazil to new technological frontiers for the study of materials, as in the field of archeometry.

“…Investigations of rupestrian paintings or painted rock art can be found [5,6], but the most common material studied is ceramic. Those studies focused on ceramics produced by people from the North and Northeast (States of Pará, Maranhão, Amazonas, and Rondônia) [7][8][9][10][11][12][13][14][15], South (States of Rio Grande do Sul, Santa Catarina, and Paraná) [16][17][18][19][20][21][22], Southeast (States of São Paulo and Minas Gerais) [23][24][25][26], and Midwest of Brazil (Pantanal region) [27]. Some studies on organic materials exist and focus on resins [28,29], feathers [30,31], and woods [32].…”

The Brazilian Legal Amazon region is divided into at least 155 ethnic groups and has the largest concentration of Indigenous people globally. It represents one of the most extraordinary levels of human, cultural, and artistic diversity, but its material culture is one of the least well-studied. This is especially true in technical art history and conservation science, largely due to (1) the limited international awareness of the richness of materials and techniques used by these Indigenous people and (2) the limitations of knowledge access for many scientists to literature usually published in Portuguese within social sciences and humanities. One result is that these arts are marginalized within technical art history, conservation, and conservation science. To address this knowledge gap, the authors explore 70 materials—among them pigments, dyes, binding media, and varnishes—used for paint production and coloring processes, including syntheses. The authors facilitate research possibilities within technical art history, conservation, and conservation science by presenting data from historical texts from the 18th and 19th centuries and more recent scientific literature. The work aims to build a more global, inclusive, and decentralized vision of art history and to create a more pluralistic narrative of Indigenous art history from South America.
