“…The experiment was done with a 2 MeV proton microbeam (9 μm 2 beam area) [1,2]. A Canberra HPGe detector (180 eV FWHM at 5.9 keV), covered with a mylar funny filter (52 μm thickness, 11 % hole) to reduce the intensity of the peaks in the low spectral region (below 4 keV) was used.…”

“…Elementos geologicamente associados a um depósito são os elementos do grupo da platina (PGE -Platinum Group Elements), que incluem o paládio (Pd), a platina (Pt), o ósmio (Os), o ruténio (Ru), o ródio (Rh) e o irídio (Ir). Estes metais possuem elevados pontos de fusão e ebulição, pelo que não são removidos aquando dos processos de refinação [11][12]. Como tal, a concentração destes elementos, característicos do metal e da sua proveniência, pode apontar para uma origem geológica: Pt e Pd, depósitos da América do Sul (Colômbia, Brasil e Perú); Pt, do Leste da Europa (peças mais recentes); Pd, Sn, Sb e elementos do grupo do telúrio, da Índia (após o século XVI) [6,10].…”

Technological and compositional study of the gold leaf from Baroque altarpieces-basis for a research methodology Resumo Foi estudada a folha de ouro do retábulo-mor da igreja de Jesus em Aveiro, um dos mais interessantes exemplares de talha barroca portuguesa, localizado no actual Museu da Cidade e antigo Convento de Jesus. Efectuaram-se análises qualitativas dos cortes estratigráficos por microscopia óptica e identificaram-se três camadas distintas-preparação branca, bolo e ouro-consistentes com a aplicação de um douramento tradicional. A utilização de microscopia electrónica de varrimento com espectrometria de raios X por dispersão de energia (SEM-EDS) mostrou o uso de uma liga ternária de Au, Ag e Cu com aproximadamente 22 quilates. Através de espectrometria de massa com plasma indutivo (ICP-MS) identificaram-se elementos-traço: Cr, Pt, Pd e Sn nas camadas ouro e Pb e Hg no bolo. O emprego de microfluorescência de raios X por radiação de sincrotrão (SR-µXRF) permitiu confirmar a presença de Sn e traçar o perfil dos principais elementos presentes nas amostras.

This paper gives an overview of research in or associated with the pan-European network COST Action G8, which aims at achieving a better preservation and conservation of our cultural heritage by increasing the knowledge of art and archaeological objects through advanced chemical and physical analyses. The paper is focussed on the use of various analytical techniques for the examination of cultural heritage materials and includes research examples on painted works of art, ceramics, glasses, glazes and metals. In addition attention is drawn to advances in analytical instrumentation, for example the development of portable techniques to perform analyses on site, and to the need for collaboration between people directly involved in the field of cultural heritage and analytical scientists.
