Two ancient green Chinese Pb‐Ba glass (Qin and Han dynasties) were studied with Raman microspectroscopy, scanning electron microscopy, and energy dispersive X‐ray spectrometry. Some needlelike silicates were found in the samples and inferred as BaSiO 3 , BaSi 2 O 5 , and PbSiO 3 according to the results of energy dispersive X‐ray spectrometry analysis. Then BaSiO 3 , BaSi 2 O 5 , and PbSiO 3 were synthetized in laboratory in order to obtain their Raman spectra. Through comparative study, the needlelike silicates in the ancient Pb‐Ba glass samples were proved to be PbSiO 3 , BaSiO 3 , and Al 2 O 3 . According to the ternary phase diagram analysis, a mechanism of local element enrichment was put forward for the barium silicate needlelike silicates (by‐products) formation in the ancient Pb‐Ba glass.
