A Liuli ring was nondestructively analyzed by EDXRF probe, to discuss the characteristic of chemical composition and the producing place of this Liuli ring. The result reveals that the chemical composition of this Liuli ring belongs to PbOBaO SiO2 system, which is similar to Chinese special ancient PbO-BaOSiO2 glass dating from Chunqiu to East Han state. So, it was concluded that this Liuli ring was used Chinese special technology and formula, and was made in China. But on the appearance, this Liuli ring is not like a mature glass, but a faience or frit which is the compound of glqss and crystal substance.%利用EDXRF探针,对一件战国时期的琉璃环进行了无损分析,以研究其化学组成特点及产地.分析表明,这件琉璃制品的化学组成属PbO-BaO-SiO2系统,与中国春秋至东汉时期特有的铅钡硅酸盐玻璃的化学组成一致,因此判断该制品是利用我国特有的技术和原料配方,在中国制成.但从外观来判断,该琉璃制品与成熟的玻璃差异较大,而更象是釉砂或玻砂,即玻璃态和晶体物质的混合体.
