This paper deals with analyses made on fragments of glass beakers found at Helgö in Sweden and Spong Hill in Norfolk, England, by both energy dispersive x-ray fluorescence and neutron activation The beaker types considered are of Snartemo and Kempston types. Significant differences in the content of minor and trace elements have been discovered which distinguish the two beaker types and can be interpreted as implying the use of differentsands and possibly different decolorants. It is felt that these discrete compositions imply the use of geologically different raw materials within the same overall tradition of glassmaking. It is not possible to identify specific locations of manufacture for either group, and therefore one cannot dismiss the possibility, however remote, that the Snartemo group is of Scandinavian origin. -- AATA
