Material Characteristics and Comparison of Silver Foil Glass Beads Excavated from the Tomb of King Muryeong in Korea

This study investigated the comprehensive characteristics of silver foil beads excavated from Tomb King Muryeong, based on composition analysis and glass morphological characterization. The major element components metal were using a scanning electron microscope (SEM) equipped with an Energy Dispersive X-ray spectrometer (EDS). Trace elements determined LA-ICP-MS to constrain source raw material. recognized through optical microscope. As result analysis, was detected as pure in both gold- silver-colored beads. chemical soda glass, Na+ acting flux CaO added stabilizer improve durability. It confirmed that plant ash used because MgO K2O found contain more than 1.5%. Through trace it gold made different materials. content Fe2O3 significantly higher gold-colored Therefore, can be interpreted tomb Muryeong intentionally achieved appearance by controlling color outer glass. showed differences according manufactured single or segment types, but types.
