A Saga feudal clan established a reverberatory furnace before than other feudal clans. There was advanced orchid scholastic ability in a Saga feudal clan Because the X-ray absorption minute structure analysis and neutron radiation analysis are beneficial in the analysis of an iron lump, We used these to the analysis of the iron lump that was cast with the reverberatory furnaces of Saga, Azimu, Rokuo,,Nirayama. It becameclear that these reverberatory furnaces used iron sand mainly, as a result of analysis. We analyzed the steel cannon that toguri gallery is preserving with the method of neutron radiation analysis (NAA), So there is such a view that this steel cannon was created in America, we analyzed the cannon to examine this view. We investigated the tatara-type bellows iron manufacture that exists in Izumo. The precise technique was used the foundation part of the furnace to remove moisture in the tatara-type furnace. The arrangement of garden rocks of the foundation part is done to solidity, to eliminate moisture in the reverberatory furnace of a Kagoshima feudal clan. It is considered as the making technology of the foundation of the pedal-type furnace was used, even though the under work is not investigated. We did the survey of the steel cannon casting technology of China in a half termof 19th century in Keirin. The steel cannon was stored in Canton instructor university museum. These cannons were cast to solidity. The steel cannons that the peaceful Heaven corps spent were displayed on a peaceful Heaven memorial hall these cannons were coarse with a small size.
