title: Uranium Contents of Ancient Man-Made Glass.
abstract: The concentrations of uranium impurities in a variety of ancient man-made glasses have been determined by counting the sites of neutron-induced fissions. There appears to be a chronological trend from low to high and back to low uranium contents over the past three millennia. Crude estimates of ages by fission-track counting should be possiblewith considerable labor for the group of glasses which was found to have the highest concentration of uranium.
