| Outline of Final Research Achievements |
Laser-induced breakdown spectroscopy (LIBS) has not so much been applied to Japanese archaeological finds. The researcher attempted analyses of archaeological pottery and glass objects using the technique. Its merits such as the speed of analysis and the sensitivity of light elements were confirmed. On the other hand, the surface conditions or matrix of the objects cause some problems with quantification. To our regret, finding of borosilicate glass from excavated glass objects was not accomplished.

| Academic Significance and Societal Importance of the Research Achievements |
これまで出土した遺物の材料やどこで作られたのかを探るために、様々な元素レベルの分析法が開発されてきた。遺物研究では実物をなるべく痛めることなく、迅速に正確なデータが得られることが重要であり、本研究では最近機器開発が進められてきたレーザ誘起ブレークダウン分光法を用いた。これまでの方法では測定が困難であった軽元素の測定や10秒程度で測定ができる迅速性を確認することができ、今後も応用が進められるべきと考えられる。
