Development of portable X-ray analytical instruments to obtain the evidence of east-west cultural exchange through the analysis of material history of excavated artifacts

研制了便携式X射线荧光光谱仪，并在中国、伊拉克、克罗地亚、叙利亚、土耳其、埃及和博物馆使用该仪器对古玻璃进行了分析。我们的分析显示，从日本古坟出土的玻璃来自中国、泰国和印度等亚洲国家。在Byodoin发现的玻璃被发现是奈良型铅玻璃和使用中国技术生产的钾铅玻璃。我们的分析数据还揭示了地中海地区东西贸易的各个方面。

Portable X-ray fluorescence spectrometer was developed and ancient glass was analyzed by using the spectrometer in China, Inida, Croatia, Syria, Turkey, and Egypt as well as in museums. Our analysis revealed that glass excavated from Japanese Kofun came from Asian countries such as China, Thailand, and India. Glass discovered in Byodoin was found to be lead glass of Nara type and potassium lead glass produced using the technique from China. Our analytical data also revealed aspects of east-west trade around Mediterranean sea regions.
