Abstract：The cemetery of Xinfeng is located in Xi’an City, Shanxi Province, which can be dated back to the late Warring States period through the Qin dynasty (4th—3rd centuries B. C. E) to the midterm of the Western-Han to Eastern-Han dynasty (2nd century B. C. E to first quarter of 3rd century C. E. ). More than 100 glass artifacts were unearthed from 12 tombs among 700 ones in Xinfeng cemetery including eye-beads, rings and ear pendants. Five samples covering all glass types in Xinfeng cemetery were studied with polarizing optical microscopy, scanning electron microscopy (SEM) equipped with energy dispersive X-ray analysis (EDX) and micro-Raman spectrometer. The chemical composition showed that one faience bead is with potassium-calcium-soda glaze layers and the other four lead-barium glass. Copper is the coloring agent for the blue glass, and copper allied with iron for the green ones. The red glass was colored by Fe2O3 particles and the opacity of the white glass was due to the crystals in the matrix. The two colors of the eye-bead were due to copper and iron respectively. Some technologies of lead-barium-soda glass and potash-calcium glaze eye-bead are also discussed in the text.
