| Outline of Final Research Achievements |
We investigated mechanisms of an ancient bonding technology of granulation and its techniques to equalize colors of bond parts and granules/metal surfaces from the viewpoints of material science and art. Toward this aim, bonding experimental studies were conducted through different heating atmospheres, temperatures, and time, considering gold alloy compositions of the granules and surfaces as well as copper compounds included in brazing materials in order to evaluate bonding conditions and generated colors.
As a result, ball shear testing and X-ray CT of the bond parts revealed that the use of brazing materials including copper carbonate has achieved a successful granulation in an electric furnace, reducing copper carbonate to form copper. Examinations of colors of the bond parts and granules/surfaces with a spectrocolorimeter and the naked eye further demonstrated that gold alloys rather than pure gold generated reduced color unevenness among the bond parts and granules/surfaces.

| Academic Significance and Societal Importance of the Research Achievements |
古代のマイクロ接合法である金や銀の微細粒を基板に接合させる粒金技法は、途絶えてしまい現代に伝承されていない。芸術学的視点をもつ金工作家と、材料学的視点をもつマイクロ接合の専門家が連携して研究を進め、その謎とされる古代粒金技法のメカニズムを解明し、普遍化するため研究を実施した。その研究成果を、大学教育の中で活用していくことが重要である。今まで出来なかった粒金技法を現代ジュエリーの制作に生かす指針を示すことができた。
また、国内の美術館と連動して、収蔵粒金作品を非破壊分析調査して組成を明らかにしたり、制作工程を推定したりしたことにより、社会的意義があったと考える。
