The study on iron-smith in the ancient japan

本研究计画为日本古代铁匠技术之研究。研究方法主要依靠考古实物，如铁渣、铁器和铁匠的实验工作，研究结果如下：日本的铁匠作业始于弥生时代中期。这项技术是从古代中国和古代韩国传来的。起初，古代日本的铁匠不能控制1,000℃以上的高温，所以当时的铁匠的工作并不产生高温下产生的铁渣。在古洪早期，突然出现了大尺寸和重的铁渣。这时铁匠技术已经成熟，并从韩国引进。然而，高水平的铁匠技术在汉代晚期才在乡村中出现，作为实验工作的结果，我们对古代铁匠的一些技术进行了实验，得到了各种各样的铁渣，并制作了各种铁器模型，如斧头、锄头、镰刀、铁匠材料等。

The research project is the study on the iron-smith technique in the ancient japan. The methods of the research depend on archaeological objects, for example iron-slag, iron-articles and experimental work of iron-smith.The results of the research project are below.In Japan, the operation of iron-smith began in the middle of the yayoi period. The technique was brought from ancient china and ancient korea. At first ancient japanese smiths were not able to control high temperature over 1,000℃, so the work of iron-smith at this time did not produce iron-slags yielded under high temperature. In the early kohun period suddenly large-sized and heavy iron-slags made an appearance. At this time iron-smith technique was accomplished and was brought from the south korea. However, it was in the late kohun period that the high level technique of iron-smith was available in villages.As results of experimentel work, we experimented some technique of ancient iron-smith and got many kinds of iron-slag and we made many kinds of model of iron articles, for example axes, hoes, sickles, materials for iron-smith.
