Study on Analysis and Conservation of Archaeological Materials in Japan and Korea

该计划的目标：a）交换考古材料分析研究的数据b）交换考古材料样本c）考古材料保护技术的比较研究活动概要：<Samples>水浸木：从希南（韩国）和江濑（北海道）的沉船中取样。漆：日本的绳纹时代、弥生时代和古坟时代涂有漆的船只和梳子。- 来自Tahori网站的Urushi。朝鲜，第6 C.金属对象：青铜器文物-从古坟时期在日本。日本和韩国古坟时期的铁剑。<Results and Discussion>含有铁盐的饱水木材在潮湿的环境下不牢固。采用PEG法处理后的木材应保持干燥状态，比较了两种用于冷冻干燥的预处理方法。一种是使用叔丁醇溶液，另一种是PEG的水溶液。许多漆器文物已经。在日本和韩国被挖掘出来。它的起源始于。从青铜时代开始，大约在B. C. 100.日本出土的青铜器数量大，表面状况多样。其中一个表面覆盖着厚厚的铜绿。另一种表面光滑，像黑色或银色的玻璃。BTA与赤铜矿反应迅速，但与碲铁矿反应缓慢。制备了两个样品。准备了两个样品，一个是富的，另一个是贫的。两个表面都用腐蚀抑制剂处理。加速恶化治疗后，观察到的生存状态无差异。

Objectives of the program :a) Exchange of, data on analytical research of archaeological materialsb) Exchange of samples of-archaeological-m-aterialsc) Comparative study on the conservation techniques of-archaeological materialsSummary of Activities :<Samples>Water-logged Wood : Sampled from the shipwrecks from Sinan (Korea) and Esasi (Hokkaidou).Urushi : Vessels and combs coated with Urusi from the Joumon period, Yayoi period, and Kofun period in Japan.Vessels and bow with. -Urushi from Tahori site in. Korea, the 6th C.Metal Objects : Bronze artifacts-from the Kofun period in Japan. Iron swords from the Kofun period in Japan and Korea.<Results and Discussion>A water-logged wood containing iron salt is-not strong against the wet condition. This type of wood treated by PEG method should-be kept in a dry condition.Two methods of pretreatment for freeze-drying were compared for shipwrecks. One of them is using a solution of tertiary butanol, and the other is a solution of PEG in water.Many of, urushi artifacts have been. excavated in Japan and Korea. Its origin in started. from Bronze age, around B. C. 100.The bronze artifacts excavated in Japan have a large, variety in surface condition. One of them has surface heavily covered with thick patina. The other has smooth surface, like a glasses which has a black or silver color.BTA reacts quickly With cuprite, but slowly with tenorite. Two samples were prepared. Two samples were prepared, one rich and the other poor in tenorite. Both surfaces were treated with a corrosion inhibitor. No difference in the surisce state was observed after a treatment of accelerateing deterioration.
