要旨：
本講演では我々の融合研究の経緯と成果、ならびに今後の研究への展開を述べる。我々は在来知を主唱した故長野暹名誉教授(以下長野)を中心に歴史学・考古学と分析化学との融合研究班を組織し、幕末佐賀藩の大砲製造における製鉄技術と鉄素材を探る研究を始めた。まず各地に遺る鉄製砲弾や製鉄炉跡を探究し、得られた鉄遺物の自然科学分析を行った。幕末佐賀藩では他藩に先駆け反射炉を構築、アームストロング砲の製造まで行った。この製造で用いた鉄素材の産地探索で出雲産砂鉄を集中的に採集・分析を行い、さらに他地域の製鉄遺跡や砂鉄素材の探究へと進み、 現在では外来鉄の可能性も含めて研究の展開を図っている。
Abstract：
In this lecture, we will discuss the results of our interdisciplinary research, as well as future developments in our research. We organized an interdisciplinary research team combining history. archaeology, and analytical chemistry, led by Professor Susumu Nagano, who advocated the Indigenous Knowledge, and began the research of the iron-making techniques and iron materials used in the manufacture of cannons in the Saga domain at the end of the Edo period. We first explored iron cannonballs and iron-making furnace ruins that remain in various locations, and conducted natural science analysis of the iron artifacts we found. The Saga domain at the end of the Edo period was the first to build reverberatory furnaces, and even manufactured the Armstrong cannon. In searching for the source of the iron material used in this manufacture, we focused on collecting and analyzing iron sands from Izumo. We then moved on to exploring iron-making ruins and iron sand materials in other regions, and are currently expanding our research to include the possibility of imported irons.
