The glasses of Ljubljana, related historically to the spread of glassworks in the Venetian style, were studied by a combined PIXE/PIGE method based on the in-air proton beam. The contribution of PIGE was determination of Na, Mg and Al oxides that provided (1) non-ambiguous characterization of the alkali and limestone component, (2) stable concentration evaluation algorithm relying on the normalization of all metal oxides to 100%. The majority of investigated samples form a compact group with small variations due to the alkalis used; a clear distinction from a few imported objects confirms local production. The raw materials in medieval glassworks differ significantly from those of Late Antiquity. [Copyright &y& Elsevier]
