This paper reports the results of elemental analysis, using laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS), of 30 glass beads from an assemblage of beads excavated at medieval al‐Basra, Morocco. Six chemical glass types are represented and their characteristics and geographical origins are discussed, with reference also to the techniques used to make the beads. The presence of numerous beads of lead–silica glasses is of particular interest. The morphological, technological and chemical analyses of the bead assemblage shed light on al‐Basra's trade connections.
