| Outline of Final Research Achievements |
The research team considered the nature of what is commonly thought to be wear from hand-rubbing on Yayoi- and Kofun-period bronze mirrors by analyzing the samples through high-definition visual analysis utilizing scanning electron microscope, 3D microscope and sliding tests. While resin coating on mirrors that have undergone conservation treatment obstructed the magnified high-definition visual analysis, it enabled an increased understanding of the issues surrounding conservation methods for bronze mirrors. The wear experiment comprised extended wet sliding tests utilizing a cotton cloth. The experiment didn't yield surface wear. This suggests that the archaeological theory proposing that surface wear was due to long-term hand-rubbing requires reconsideration.
