Exploring the unknown Balkans: Early Byzantine glass from Jelica Mt. in Serbia and its contemporary neighbours

The concentrations of Na, Mg, Al, Si, S, Cl, K, Ca, Ti, Mn, Fe, Ni, Cu, Zn, Br, Sr, Zr, Sn, Sb and Pb in 40 archaeological glasses from the Early Byzantine Jelica site in Serbia, are determined by PIXE/PIGE. Geochemical and multivariate analysis shows it corresponds to Foy series 2.1 and 3.2. Regionally, it is similar to the contemporary 6th century composition from Lower Danube (Bulgaria), Cariin Grad (Serbia) and Butrint (Albania). The results indicate that trade routes between these inland regions and the rest of the Empire were mostly open even during turbulent times of the 6th century.
