CLUSTER ANALYSIS APPLIED TO SPECTROCHEMICAL DATA OF EUROPEAN MEDIAEVAL STAINED GLASSES

Abstract
Cluster analysis has been applied to the spectrochemical data obtained in the analysis of some mediaeval glass fragments. Differences have been observed between Catalan glasses and all European glasses, and also between European glasses from different countries. To distinguish geographical origin sodium, potassium, calcium, magnesium and aluminium have been shown to be adequate.
