Scientific Analysis of Amber Ornaments Unearthed from Northern Wei Dynasty Tombs in Datong, Shanxi

Ancient amber is regarded as a significant tangible witness to material exchanges and cultural communications between China and foreign countries. This paper selects typical amber specimens unearthed from Northern Wei Dynasty tombs in Datong, Shanxi, as the research objects. Detection is carried out utilizing techniques such as extended depth-of-field three-dimensional microscopy, infrared spectroscopy, and Raman spectroscopy. Furthermore, by integrating relevant perspectives from archaeology and historiography, it delves deeply into the raw material sources, processing techniques, decorative pattern characteristics, and cultural connotations of these amber artifacts.The research findings indicate that the raw materials of the amber specimens analyzed in this paper, which were unearthed during the Northern Wei Dynasty in Datong, originated from the Baltic Sea. Some of them are locally processed products made from foreign raw materials, while it cannot be ruled out that the finished products were directly imported for the others. Amber artifacts can be classified into two categories: plain-surfaced and decorated ones. The latter mainly feature string patterns, lotus patterns, honeysuckle patterns, and auspicious beast patterns. The shapes and decorative styles of these artifacts not only reflect the dissemination of Buddhist culture but also embody the historical characteristics of the multicultural integration during the Northern Wei Dynasty. This study represents the first scientific analysis of amber unearthed from tombs dating back to the Northern Wei Dynasty in the Datong region, providing material evidence and scientific basis for the spread of ancient amber and the Sino-Western cultural and trade exchanges observed along the Silk Road.
