Investigation of Anti-mold Measures in Mezurashizuka Tomb
We gave instruction and advice and participated in a survey to conserve and restore the Mezurashizuka Tomb, a special historical site. The Mezurashizuka Tomb is one of the decorated tombs in which patterns were drawn using red and gray pigments.
In time, the tomb mound was lost, but the stones used for the chamber became exposed, with the surroundings protected by walls. A large amount of mold had formed on the surfaces of stones in these walls, and it was found that the pigments were unclear. Our preliminary survey for full-scale restoration work consisted of sampling the mold and using ultraviolet rays and brushes to try to remove it. We also measured the temperature on the surface of the stones and the amount of moisture using a near-infrared moisture meter, and examined the effects of disposal on the stones. As a result of this investigation, full-scale restoration work will be carried out in the next year.
Both emergency treatment and middle and long-term conservation measures, including the environmental control within the walls, have been requested.
