Specialists from science, archaeology and technology fields discussed each other about the casting process of East Asian bronze objects. These works were summarized in the next reports.
1. Lead isotope ratio measurements of old East Asian bronze objects
About 300 of old bronze samples from various sites in Japan, China and Korea were measured their lead isotope ratios with surface ionization mass spectrometer.
2. Reexamination of Fukuda type Dotaku
The evaluation of age and the provenance study of Fukuda type Dotaku were discussed. The archaeological featuers were reexamined with scientific data.
3. Data bank of chemical composition of Japanese bronze objects in Yayoi and Kofun periods
Chemical composition of about 200 samples of bronze objects were summarized
4. Computer simulation of bronze casting process
The casting process was simulated with computer to reproduce the ancient bronze objects
5. Casting examination of Dotaku using stone mold
Dotaku was cast using stone mold. The process of casting was recorded precisely.
6. Mass production method of arrowhead in Kofun period
From the archaeological aspects, the mass production method of arrowhead was examined.
7. Discussion of mold of Dotaku
The significance and feature of casting mold was reexamined to reproduce the Dotaku.
