郑州地区出土战国蜻蜓眼珠饰的无损分析及制作工艺初探

A non-destructive analysis of the Warring-States eye-beads unearthed in Zhengzhou and their manufacture techniques

本文运用激光剥蚀电感耦合等离子体质谱仪、X射线荧光分析仪、激光共聚焦显微拉曼光谱仪等无损分析方法,对郑州地区出土的17件战国蜻蜓眼珠饰进行元素成分及物相分析,分析表明这17件蜻蜓眼可分为铅钡费昂斯、铅钡玻璃、钾钙费昂斯、钾钙玻璃4种类型。综合考古类型学观察、超景深三维视频显微镜观察、元素成分、物相分析等结果,推断其制作工艺及技术来源,并运用主成分分析和稀土元素分析对产地来源进行初步探讨。

The author analyzes the chemical composition of the compound eye-beads of the Warring States period unearthed at Zhengzhou, by using non-destructive analysis methods such as Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry(LA-ICP-MS), X-Ray Fluorescence analyzer(XRF)and Laser confocal micro Raman spectrometer(Ramen).The analysis shows that the 17 compound eye-beads can be divided into four types, which are potassium calcium faience, potassium calcium glass, lead barium glass and lead barium faience. The manufacture process is inferred based on the results of archaeological typology, 3D video microscope observation, element composition and phase analysis. Principal component analysis and rare earth element analysis were used for a preliminary understanding of the origin.
