Micro-Raman spectroscopy and complementary techniques (hXRF, VP-SEM-EDS, μ-FTIR...
Coccato, A; Costa, Mafalda; Rousaki, A; Clist, B; Karklins, K; Bostoen, K; Manhita, A; Cardoso, A; Dias, CB; Candeias, A; Moens, L; Mirao, JIn the framework of the inter-disciplinary KongoKing project, a set of beads from archaeological excavations in the Democratic Republic of the Congo was analysed by means of a minimally invasive, multi-analytical approach based on micro-Raman spectroscopy. The full characterization of the materials, including glassy network, opacifiers and colorizers, was achieved thanks to the combination of data from handheld...
Evaluation of portable Raman spectroscopy and handheld X-ray fluorescence analy...
Lauwers, D; Candeias, A; Coccato, A; Mirão, J; Moens, L; Vandenabeele, PIn archaeometry, the advantages of a combined use of Raman spectroscopy and X-ray fluorescence spectroscopy are extensively discussed for applications such as the analysis of paintings, manuscripts, pottery, etc. Here, we demonstrate for the first time the advantage of using both techniques for analysing glyptics. These engraved gemstones or glass materials were originally used as stamps, to identify the owner,...
