- 描述： 为探讨薛家岗文化玉器的制作工艺,采用体视显微镜进行微痕观察,并通过X-射线衍射分析、红外光谱、拉曼光谱等分析仪器的物相测试,对安徽省文物考古研究所和安徽省博物馆所藏的127件薛家岗玉器的表面加工微痕迹进行研究分析.结果显示:薛家岗玉器大多光素无纹;玉料主要以闪石玉为主,结构普遍较粗;开料以线切割技术为主,片切割技术为辅;钻孔主要为两面对钻,工具有实心钻和空心管钻,孔壁常留有螺旋钻痕和对钻台痕;玉器整体经过打磨抛光工序;出现了破裂玉器的接合修复技术;薛家岗文化晚期出现了镂空技法、减地浅浮雕技法以及阴线刻技法,体现了玉器制作工艺的明显进步.127 pieces of Xuejiagang jades preserved at the Institute of Archaeology of Anhui Province and Museum of Anhui Province were analyzed to study the carving technology of jades. Stereomicroseope was used to observe the surface micro -traces. X -ray diffraction analysis, infrared spectroscopy and Raman spectroscopy were performed for phase studies. The results show that Xuejiagang jades are almost plain ,without surface pattern. The jade material is mostly nephrite of a crude structure. The opening technique is mainly line - cutting with piece - cutting as a supple-ment. Holes were mainly drilled from both sides, and the tools used were both solid drills and hollow drills. There are spiral drilling traces and two - surface - drilling traces left on the hole wall. The entire jade had been burnished and polished. Broken jade could have been joint - repaired. Techniques such as hollow - carving and has - relief by reducing and line -incising appeared in the late Xuejiagang culture, reflecting remarkable progress in carving technology.
