Determining the provenance of the European glass beads of Lumbu (Mbanza Kongo, ...
Costa, Mafalda; Barrulas, Pedro; Dias, Luís; Lopes, Maria da Conceição; Barreira, João; Clist, Bernard; Karklins, Karlis; de Jesus, Maria da PiedadeA collection of glass beads found in Lumbu (Mbanza Kongo, Angola) were analyzed by means of a multi-analytical minimally invasive methodology, which included handheld X-ray fluorescence (hXRF), variable pressure scanning electron microscope coupled with energy dispersive X-ray spectrometry (VP-SEM-EDS), micro-Raman spectroscopy and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Trace e...

Coccato, Alessia; Costa, Mafalda; Rousaki, Anastasia; Clist, Bernard-Olivier; Karklins, Karlis; Bostoen, Koen; Manhita, Ana; Cardoso, AnaIn 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...
