Abstract
AbstractThis study analyzed two glass eye beads discovered in an ancient tomb complex at Dongxin Furniture Square in Datong, Shanxi Province in China. The tomb complex was dated to the Northern Wei Dynasty (398–494 AD), when Datong was known as Pingcheng. We used scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS) as well as a 3D microscope system with ultra-depth of field to conduct non-destructive tests on the beads. We examined the beads’ manufacturing techniques, including matrices, eye patterns, and bead holes. The composition analysis revealed that both beads belonged to the mix of v-Na-Ca and m-Na-Al glass system, which is a key indicator of local production in Java. The bases were colored using Co2+, whereas the white, red, and yellow colors of the eye patterns were achieved using SnO2, Cu2O, or Cu0, and PbSnO3, respectively. These findings indicated that both objects were Jatim beads originating in the Kingdom of Java in Southeast Asia. This study provides valuable insights into ancient trade routes between different regions and offers reliable scientific evidence of the glass trade and technical exchanges in ancient times.
