摘    要:Thirteen different components of six samples belonging to stained medieval glass windows and twelvesimilar samples found in the archives of Girona Cathedral(Catalonia,Spain)during restoration workwere determined by x-ray fluorescence analysis.The use of display and cluster analysis methods,principal components analysis,non-linear mapping,minimal spanning tree and agglomerativehierarchical clustering applied to these results,together with those of nine samples from the samecathedral previously studied,showed the presence of a quite compact cluster formed by the soda-typesamples,indicating a probably similar origin and confirming the peculiarities of this Mediterranean area.The potash-type glasses were highly scattered with little similarity among them,suggesting a likelydifferent source of these samples.The twelve glasses of strictly unknown origin were found to have a highdegree of resemblance to the samples of known context,thus excluding the possibility of them beingsamples made in a very different age or site.Three of them were classified into the same group as thewell-defined soda-type glasses by the pattern recognition method SIMCA.

Abstract:Thirteen different components of six samples belonging to stained medieval glass windows and twelve similar samples found in the archives of Girona Cathedral(Catalonia,Spain)during restoration work were determined by x-ray fluorescence analysis.The use of display and cluster analysis methods, principal components analysis,non-linear mapping,minimal spanning tree and agglomerative hierarchical clustering applied to these results,together with those of nine samples from the same cathedral previously studied,showed the presence of a quite compact cluster formed by the soda-type samples,indicating a probably similar origin and confirming the peculiarities of this Mediterranean area. The potash-type glasses were highly scattered with little similarity among them,suggesting a likely different source of these samples.The twelve glasses of strictly unknown origin were found to have a high degree of resemblance to the samples of known context,thus excluding the possibility of them being samples made in a very different age or site.Three of them were classified into the same group as the well-defined soda-type glasses by the pattern recognition method SIMCA.
