Study on Micro-analysis for Cultural Property

本研究主要对16 - 19世纪外销漆器进行微观分析研究。在这些漆器中，日本漆器（漆）是最珍贵的，但也有很多来自中国的其他漆制品。琉球（今冲绳县）和东南亚各国，甚至还有仿欧洲漆器制成的。因此，了解其所用的材料，对确定其来源和修复方法，包括材料的选择，都是非常重要的。开发了质谱法和漆样横截面检查法，并应用于多件出口漆器样品，结果表明，许多漆制品都用欧洲漆修复。这意味着需要提前对后期漆层是否应去除的政策以及修复所用的材料和技术进行仔细的研究和讨论。研究结果将发表在我们最近的合作著作以及3月11-13日在慕尼黑举行的“东亚和欧洲漆技术”会议上。1999年由东京国立研究所和巴伐利亚保护办公室。

Study on micro-analysis was conducted mainly on exported lacquer wares from 16 to 19 century in this research. Among these lacquer wares, those made of Japanese lacquer (urushi) are the most precious but there are lot of other urushi wares from China. Ryukyu (now Okinawa Prefecture) and South-east Asia countries, and even also imitations made of European lacquer. So it was very important to know the material used in order to decide their origins and restoration ways including its materials.In this study the micro-analysis methods using Pyrolysis Gas chromatography/Mass spectroscopy and that using the examination of cross sections of lacquer samples were developed and applied to many samples from exported lacquer objects.The result by the methods deve1oped showed that many urushi objects were restored with European lacquers in later period, which meant careful research and discussion on the the policy whether the layer applied in later period should be removed or not and on the material and technique used for restoration would be needed in advance.The results will be published recently in the book of our collaboration work and also in the proceedings of "East Asian and European Lacquer techniques" held in Munich from 11-13 March, 1999 by Tokyo National Institute and Bavarian Conservation Office.
