lead-potash-silica glass, potash-lime-silica glass, specific gravity measurement, energy dispersive X-ray fluorescence analysis, lead isotope analysis
Seven glass shards of the Edo period, excavated from Manzaimachi site in Nagasaki City, were examined using specific gravity measurement, X-ray fluorescence analysis (XRF), and lead isotope analysis. Five lead-potash-silica glass wares and two potash-lime-silica glass wares were identified according to their chemical compositions, corresponding to the results of specific gravity measurement. According to the archaeological information and the shards’ lead isotope ratios, three lead-potash-silica glass wares were made in Japan, while the other two were assumed to have been brought from China.
