Characterization of some ancient glass vessels fragments found in Xinjiang, China, using a portable energy dispersive XRF spectrometer

Abstract

AbstractIn this article, a portable energy dispersive X‐ray fluorescence spectrometer having determination capability for elements of Na and Mg is applied to characterization of the 58 ancient glass vessels fragments found in Xinjiang, China, successfully. These ancient glass samples were found in different historical sites dated from the Han Dynasty (202 B.C.–220 A.D.) to early Yuan Dynasty (1271–1368 A.D.). The chemical composition difference between the original weathered and inner fresh surfaces is distinguished. Using Mg, Ca, Al and K as the diagnostic elements, the glass samples analyzed are mainly classified into three types through cluster analysis. Each type of glass seems to be produced under different recipes. The techniques used to make these glasses and their possible provenances are discussed briefly. The obtained results provide new useful information for further understanding of the exchange and trade networks related to early glasses found in Xinjiang, China.
