Nara unearthed glass plates or high-grade products from Sassanian Persian

According to a report by the Japanese media such as Asahi Shimbun in November, there were a group of glass plates unearthed from No. 126 old burial mound of the Chitose old Tomb in Shinsawa-shi, Nara, Japan. Analytical scientists Abe and others were also studied by Tokyo University of Science and Technology. By fluorescent X-ray analysis, it was found that its chemical composition was almost identical to that of the glass composition from the Roman Empire. The glass products in Japan's late 5th-century tombs were derived from ancient Roman claims and were scientifically confirmed for the first time.

This in-depth analysis of the cultural relics material shows that this glass plate is a high-grade product containing only a small amount of impurities and contains the plant ash that is unique to the glass products at that time. Abe and other researchers used a large-scale irradiating device at Sayo-cho, Hyogo Prefecture to perform high-energy X-ray fluorescence X-ray analysis on the powders, and detected the metal elements that were used by the Roman Empire until the 2nd century AD. The glass plate is most likely from the Roman Empire. Scientific analysis of the chemical composition of glass is an important method for understanding the raw materials and the place of collection. One of the important indicators is the impurities it contains.

Abe et al.'s study also discovered the chemical composition of the round beam glass bowl unearthed in the 126th grave with the above-mentioned glass plate in 1963, and the relics of the Taisei Palace in the capital of the Persian Sassanid Kingdom (226-651). The pieces of glass found are consistent. Judging from its exterior features such as its shape, this glass bowl unearthed in Japan can also be confirmed as a Persian Sacristy product. Its appearance is pale yellow-green, its caliber is about 8 cm, its height is about 7 cm, and its thickness is about 1 to 1.5 mm. The Taixi Feng’s Palace is located on the left bank of the Tigris River in the southeast of Baghdad, the capital of Iraq. After the rise of the Persian Empire, it became the capital of the Persian Sassanid dynasty and the center of the Nestorian religion.

This major discovery shows that in the 5th century, Japan had glassware from distant and exotic countries. It was an outstanding expression of the East-West trade network and cultural exchanges in the vast region of Europe and Asia. Professor Yosuke Giguchi of the Silk Road Archaeologist at Sanyo Gakuen University in Japan pointed out that the possibility of glass products being introduced into Japan through the Central Asian region exists. Therefore, it is understandable that the time difference between Western production and arrival in Japan is also understandable. of.

The results of this research were announced in November at the Japan Glass Technology Society of Tokyo University of Science. Glass trays and beam cups have been assessed by the authorities as an important cultural property in Japan and are currently being exhibited at the Tokyo National Museum of Heisei for a short time.
