In japan, glasses came into use in the Yayoi period and continued to be used through the Kofun, Nara and Heian periods mainly as accessories for selected people. We have determined the chemical composition of a number of specimens of every period by using the X-ray fluorescence spectroscopy, neutron activation analysis and PIXE method. As for the specimens which contain more than 1 % lead, the lead isotope method was applied to see the provenance of glass material. The results are as follows:
1) Glasses of the Yayoi period.
Green glasses mostly excavated in northern Kyushu is high PbO-high BaO glasses which originated from China.
Blue Ca-alkaline glasses are sometimes of high K content.
2) Glasses of the Kofun period.
Blue beads typical to this period contain sometimes % order of Pb. This Pb is of Japanese origin, thus indicating the existence of glass making in this period.
The high-PbO glasses in the late Kofun period contain the Pb of Korean origin.
3) Glasses of the Nara and Heian periods.
Three high PbO specimens (one from the Nara period and the other two from the Heian period) all contain the Pb of Japanese origin. The Pb of the glass in the Nara period has exactly the same isotope ratios as those of the Kocho-Juni-Sen (early Japanese coins of these periods). The two specimens from the Heian period contain the Pb from the Taishu mine in Tsushima.
