A mustard-gold-colored talc bead was recovered during the 2014 excavation campaign carried out in Lumbu (Mbanza Kongo, Angola) together with the nineteenth-century glass trade beads imported from Bohemia and Venice. Results from this multianalytical and minimally invasive study suggest that this bead may have been brought to the kingdom’s capital by means of an established intra-kingdom trade network or as an o...

A 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...
The glass bead assemblages recovered during the 2014 excavations of the ruins of Kulumbimbi located in Mbanza Kongo (Angola) were analyzed by means of a multi-analytical minimally invasive methodology, which includes 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 induct...
