Comprehensive Research on the Preservation and Restoration of Wall-Paintings from Central Asia collected by the Otani Expedition

目前收藏在国立中央博物馆（首尔）（以下简称国立中央博物馆）的中亚艺术品是大谷的藏品之一。这些藏品被捐赠给日本殖民政府博物馆，光复后被国立中央博物馆收藏。大谷的另一部分藏品也保存在东京国立博物馆（以下简称TNM），一直是研究中亚壁画的宝贵资料。美术馆的壁画在捐赠后没有被碰过，因此有必要采取复原和保存措施。TNM的壁画已经修复并展出。然而，自TNM壁画开展以来，保护技术和观念的情况发生了变化。现在，壁画的保护有了进步，一方面留下了壁画的信息，另一方面也引入了对壁画本身影响较小的新的保护材料。此外，从艺术史的角度对壁画进行研究，如对颜料和制作技术的研究，以及从保护科学的角度进行研究，已经成为一种标准。此次研究是由国立美术馆保护科学部的工作人员和美术史研究人员共同进行的，形成了一个日韩合作项目。使用x射线荧光法和数码摄影对大谷收藏的三幅壁画样品的颜色和草稿线进行了光学分析。在上述分析中，采用了紫外和红外光束的无损检测方法。最终的修复方法于2004年确定，并于同年实施。研究结果汇编成一份报告。

Objects of Central Asian art now stored at the National Museum of Korea (Seoul) (hereafter NMK) are part of the Otani collection. The collection was donated to the Museum of Japanese Colonial Government and, after the liberation, the collection become the possession of the National Museum of Korea. Another part of the Otani collection is also stored at the Tokyo National Museum (hereafter TNM) and has been a precious source for conducting research on Central Asian wall paintings. Since the wall paintings at the NMK have not been touched since they were donated, restoration and preservation measures are required. The wall paintings at the TNM are already restored and have been on display. However, the situation of conservation techniques and concept has changed since the wall paintings at the TNM were carried out. Now, the conservation of wall paintings has advanced, one the one hand, leaving information of wall paintings, and, on the other hand, to introduce new conservation material which less affect the paintings themselves. Additionally, research of wall paintings from the art historical perspectives, such as studies of paints and manufacturing techniques, as well as from conservation science have become a standard. This research is jointly conducted by the staff of Department of Conservation Science at the NMK, as well as the researches of art history to form a Japan-Korean joint project.X-Ray Fluorescense method and digital photography were used to investigate optical analysis of colors and draft lines of three wall painting samples from the Otani collection. In the above analysis, non-destructive methods through ultraviolet and infrared beams were used. The final restoration method was decided in 2004 and carried out in the same year. The results of the research was compiled into a report.
