The structure and the chemical composition of the sam- ples are analysed by the undestructive methods of X-ray diffraction (XRD) and the Proton Induced X-ray Emission (PIXE) technique. The results show that these eye-beads are of glass state. Its chemical composition indicates that they belong to the glass of soda lime silicate system (Na2O-CaO-SiO2). By comparing the decorative design and the chemical composition of the samples with those from ancient Babylon and ancient Egypt, we think that these ancient eye-beads in Xichuan were most possibly im- ported from the West.展开更多
