Particle-induced X-ray emission method was applied for the determination of light and heavy elemental composition of archaeological glass seals. Quantitative information on the major, minor and trace elements and their correlations in respect of the raw materials which were used for the glass manufacturing are discussed. Although the differences of the elemental concentrations between the seals originating from different glassworks were small, discriminant analysis enabled the separation of glassworks to an extent which makes future provenance studies feasible. The need of supplementary use of energy dispersive X-ray fluorescence and proton-induced gamma-ray emission for the glass samples was also investigated.
