The arts of ironmaking "Tatara-buki process" were well known and practiced in ancient Japan.The process in the ironmaking is unique among metallurgical processes, in which pig iron or steelwith lower phosphorus and sulfur contents is produced directly from iron sand as the raw materialand charcoal as the fuel. On the other hand, in the Department of Materials Science and Engineeringthe education program of "Creative Techno-Craft" is prepared as an appropriate practice for wellunderstanding on "materials production process". The principle of the Tatara-buki ironmakingprocess was investigated for the technical education through metallographic examination forundergraduate students. And also an optimum condition for making molten iron was discussed indetail. In this experiment, iron bear (Kera) was obtained by this process in a 27 % yield. It was foundthat the homogeneous temperature in furnace plays important role in the iron making process and itshould be kept continuously high enough to do reduction of the iron sand for obtaining the iron bearin high yield.
