山东沂源出土战国皮革文物的材质鉴别

山东沂源发掘的一座战国晚期墓葬,保存完好,随葬品丰厚。其中有皮革制品,这在北方考古发掘中十分罕见。对出土皮革文物的研究,为研究北方地区战国时期的皮革制品提供了重要的实物依据。因此,本研究利用衰减全反射—傅里叶变换红外光谱(ATR-FTIR)和扫描电子显微镜(SEM)对战国皮革文物材质进行了分析鉴别,初步判定沂源出土战国皮囊为羊皮革制品。研究结果对皮革文物材质的科学鉴别提供了借鉴,为科学、有效保护奠定了基础。

Identification of waterlogged leather unearthed from a Warring States Period tomb in Yiyuan, Shandong Province

A wellpreserved late Warring States period tomb unearthed in Yiyuan, Shandong Province contained a great number of burial accessories. Among these burial accessories were found leather objects. The discovery of archaeological leather is rare in archaeological excavations in the North of China. Those objects are important for the study of ancient northern region leather tanning procedures. The archaeological leather samples were studied by using the attenuated total reflection Fourier transform infrared spectroscopy (ATRFTIR) and scanning electron microscope (SEM) to obtain insight into the functional groups and pattern of collagen fibrils of the waterlogged Warring States period leather. For comparison, modern sheep leather samples were analyzed using the same approach. The ATRFTIR comparisons of the archaeological leather and modern leather showed that the archaeological leather contained the characteristic absorption bands of the leather. The SEM studies indicated that the pattern of collagen fibrils of the waterlogged leather was similar to that of modern sheep leather. This study provides a reference for identification of the archaeological leather.
