Presentation at the 15th International Congress on the Deterioration and Conservation of Stone (Stone 2025)
From September 8 to 12, 2025, Dr. MIZUTANI Etsuko (author) participated in the 15th International Congress on the Deterioration and Conservation of Stone (Stone 2025), held at the Sorbonne University in Paris, France, and delivered an oral presentation. This congress, which takes place every four to five years, is an international forum on the conservation and restoration of sculptures and architectural structures made of stone and brick.
The congress brought together a wide range of participants, including conservation scientists and geologists studying the deterioration of stone and brick, practitioners involved in conservation and restoration, and experts in architecture and building physics. Presentations covered diverse topics, from fundamental studies on deterioration caused by air pollution and salt weathering, to new restoration techniques and practical conservation measures, as well as sustainable environmental control strategies and the evaluation of climate change impacts.
In her presentation, the author reported on research conducted at the Center for Conservation Science, Preventive Conservation Section, which focuses on improving the humid environment inside a rock cave housing a Buddhist wooden architecture, without relying on air conditioning, to preserve the structure. Following the presentation, the author received many questions and comments from researchers engaged in the preservation of cultural properties facing similar high-humidity challenges and others interested in sustainable environmental control. This provided an opportunity to exchange views on the potential for future collaboration.
Going forward, the author intends to continue actively disseminating research outcomes internationally, while also gathering the latest knowledge from around the world to further contribute to the preservation of Japan’s cultural heritage.
