Basic study on casting technique of the small bronze ware in Yayoi period

由于对弥合时期的小青铜器进行了详细的调查，因此能够区分模具材料。这是因为泥模在青铜器表面留下的痕迹与石模不同。我应用这一原理，修复了我在遥远的地方出土的青铜器生产所用的模具材料，并能够区分它是否是在什么地方生产的。结果，我可以将一个消费场所与一个生产中心联系起来，青铜器的流通系统变得清晰起来。此外，还利用地球科学的分析技术进行了模具建筑石材的生产中心识别，明确了石材的获取方法和加工方法，并能够阐明青铜器生产工艺的一端。

As a result of having performed the detailed investigation into small bronze ware of the Yayoi period, distinction of the mold material was enabled. This is because a trace to remain on the surface of the bronze ware by a clay mold is different from a stone mold. I applied this principle and restored the mold material which I used for production of bronze ware excavated in a distant place and was able to distinguish it whether it was produced in what production place. As a result, I could relate a consuming place to a production center, and a circulation system of the bronze ware became clear. In addition, I performed the production center identification of mold building stones by the analysis technique of the earth science and I could clarify an acquisition method and the processing method of stones and was able to elucidate one end of the bronze ware production technology.
