Technical research of wooden sculptures in Meiji period and study of conservation of them, especially the Gigeiten, statue ceated by kyuichi Takeuchi

本项目旨在厘清明治时期彩绘木雕的雕刻技术和整理技术，并进一步发展彩绘木雕的保护和修复技术。我们当时研究了雕塑的组成和结构，以及它们的制作技术。摄影，程序与各种相机进行。在偏振光下拍摄照片，实现物体表面颜料层的剥落和脱离。x射线照片也用于调查两个雕塑的内部结构，例如佛教神仙和古代日本真武天皇的形象。利用成像计算机软件对图像输出进行处理，通过16位数字信号分析打印出来。从上述研究工作的结果可以清楚地了解到，吉吉藤像不是江户时代的技术创造的。我们认为这幅画是经过策划和创作的，希望它能在芝加哥国际博览会上展出。在内部结构中无法检测到任何损伤，金属部件表面没有铜绿。在片状表面的修复过程中，我们使用丙烯酸树脂代替丙烯酸乳液，并尝试了新开发的清洁和稳定方法。我们参照已故的高村师傅所画的木块组合图，尝试制作了一个复制品雕塑，研究了江户时代古代佛教造像的技法。以日本佛教形象保护的历史为研究对象，考察了Bijutsuln工作室采用的保护方法对现代文化遗产的保护能力。最后，利用三维激光扫描仪对固体进行了三维测量，取得了较好的结果。

The purposes of the present project are to clarify carving technique and finishing technique of polychrome wooden sculptures in Meiji period and further to develop conservation and restoration techniques of such sculptures.We studied on composition and structure of sculpturesand making technique of them at that time. Photographic, procedures with various kinds of cameras were carried out. Photographs underpolarized light were taken to realize flaking and detachment of pigment layer on the surface of the object.X-ray photographs were also taken to survey of inner structures of two sculptures, e.g. images of a Buddhist God Gigeiten and an ancient Japanese Emperor Jinmu.Output of imaging was processed using an imaging computer software analyzing and printing-out through 16bit digital signal. From the results of above research works, it can be clearly understood that the Gigeiten image was not created by techniques in Edo period.We imagine the image was planned and created hopeing It should be displayed at the Chicago International, Exposition. Any damage could not be detected within the inner structure and no patina could be observed on surfaces of metallic parts.In processes of restorationof flaked surfaces we used acrylic resins instead of acryl emulsions and tried newly developedmethod for cleaning and stabilization of them.Referring figures showing combined blocks of woods drew by late Meister Kouun Takamura, we tried modeling up a replica sculpture and studied the ancient technique creating Buddhist Images in Edo period.Studying the history of Japanese conservation for Buddhist images, capability of conservation method adopted at Bijutsuln Studio to Modern cultural heritages was examined. Finally, three-dimentional measurement for solids were tried using a 3D-laser scanner and better results could be obtained.
