Elemental composition of glass differs based on raw material and additives used during manufacturing process, therefore elemental analysis provides substantial information from an archaeological point of view. Major, minor and trace elements in glass samples from Moldava, Kyjoy and Visegrad were detelinined. LA-ICP-MS was used for elemental analysis. Concentrations of Na2O, MgO, Al2O3, SiO2, K2O, CaO, TiO2, MnO, Fe2O3, CoO, CuO, SnO2, Sb2O3, PbO and Li-7, B-11, (45) Sc, V-51, Cr-52, Ni-60, Zn-66, As-75, Rb-85, Sr-88, Y-89, Zr-90, Nb-93, Mo-95, Ag-107, Cd-111, Cs-133, Ba-137, 139La, Ce-140, Pr-141, Nd-146, Sm-147, Eu-153, Gd-157, Tb-159, Dy-163, Ho-165, Er-166, Tm-169, Yb-172, Lu-175, Hf-178, Th-232, U-238 in 44 glass samples were detelinined. Samples were discriminated according to finding sites using multivariate statistical methods. Elements used for discrimination (Sc, Zr, Ti, Zn, La) were determined by the Random Forrest algorithm. For archaeological sites discrimination. Primary Component Analysis (PCA) was used.
