| Outline of Final Research Achievements |
In this study, we manufactured and restored pipe-shaped bengara, and performed a culture test on this bengara to investigate the microbial deterioration of red iron oxide contained in buried cultural property.
We manufactured pipe-shaped bengara and found that the color and diameter of the bengara particles changed with increasing firing temperature, which suggested a significant association among heating temperature, particle growth, and color change. In the aforementioned microbial culture using pipe-shaped bengara, plate-like crystals (Vivianite) were formed only in the presence of iron-reducing bacteria and constituted a part of the pipe-shaped iron oxide particles. Generation of plate-like crystals will not be able to grasp the shape of the pipe-shaped iron oxide particles, the possibility of deterioration due to shape change was observed.
