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 BaSiO3, BaSi2O5, and PbSiO3 according to the results of energy dispersive X‐ray spectrometry analysis. Then BaSiO3, BaSi2O5, and PbSiO3 were synthetized in...
