The glass fragments and beads excavated by a Japanese Buddhist priest, Zuicho Tachibana at the ruined sites near Kashgar, central Asia, in 1909-1911 were studied chemically in 1989. Relative density measurements and visual examination indicated that most of the beads were made of alkali-lime glasses. Two small fragments of glass vessels of unidentified shape were found by x-ray fluorescence analysis to be potash-lime glass. A porous black lump was analyzed by inductively coupled plasma-atomic emission spectrometry and found to be a slag-like substance. White crystals present in this black lump were revealed by x-ray diffraction (XRD) to be quartz crystals containing a small amount of cristobalite. This may indicate that these quartz crystals were heated to form cristobalite. Although exact dates and sites of the excavation of these glasses are unknown, this study may give some information to the archaeology of glass in central Asia.
