This seminar has been conducted since 1984 in order to convey basic knowledge and techniques to curators working on the conservation of materials at the cultural property conservation facilities. For 2017, the two-week seminar starting from July 10 attracted 31 participants throughout Japan. The curriculum of this seminar consists of two major topics: management of the facility environment such as temperature and humidity, air quality, and prevention of pest damages; factors and manners of deterioration according to material types, as well as its prevention. Experts inside and outside the Institute gave lectures and practical training. For the “Case Study,” where the participants experienced the museum environment research on site, they visited Saitama Prefectural Museum of History and Folklore. After dividing into eight groups, they implemented research under the theme set by each group, and presented the outcomes at a later date. Under the current circumstances whereby many facilities are planning large-scale renovation and major movements related to the conservation of materials, such as shifting to LED lighting, are under way, we will scrutinize the curriculum further for smooth technical transfer of proper management.
