Chemical analysis of glass from African archaeological sites has become a standard research tool over the past decades. Despite the multiplication of studies, the continent still exhibits vast unexplored regions. One of these is the surroundings of Lake Chad. This paper discusses the results of LA-ICP-MS analysis of recently excavated glass beads from the late medieval Chadian site of Tié. We demonstrate that the composition of those glass beads largely matches assemblages from along the East African coast. This indicates that most of the beads examined entered the region via a hitherto undocumented east–west Sudanic route linking Northeast Africa with Lake Chad.
