Combining the modified external-beam proton induced X-ray emission(PIXE)

inductively coupled plasma atomic emission spectrometry(ICP-AES)and other techniques

the chemical compositions

structures and other properties of some ancient glass samples of the Han Dynasty

which were unearthed from Hepu county

Guangxi

were determined.These glass samples can be classified to several glass systems

such as K2O-Si02

PbO-BaO-Si02

PbO-Si02

Na2O-K20-PbO-Si02 and (Na20)K20-CaO-Si02.But most of the samples belong to K20-Si02system glass.Due to the surface corrosion

the flux K20 in the surface of the K20-Si02glass Was lost

but with the relative enrichment of the Si02.Based on the characteristics of chemical composition and appearance of these samples

it is thought that

during the Han Dynasty

the making technique of the K20-Si02 glass in China Was influenced by the technique related to the PbO-BaO-Si02 glass from abroad.
