Secular Research of Artifacts on Post-Conservation Treatment

本研究收集了4年多来文物保存后处理现状的长期变化的现场研究资料和照片，并进行了整理和编制数据库。值得注意的是，与现场调查相比，发现的文物样本分析的因素和结果发生了以下变化：保存处理过程：木制品上化学试剂的分离，金属制品因防腐不良而出现的腐蚀开裂现象，补树脂部位钙盐的分离等。展示/储存的地点和环境：化学试剂的洗脱，高湿度导致的发黑和污渍的出现，干燥和湿度调节剂的功能下降，工件表面和颜色的变化，补充树脂的变质等。处理：由于运输和过度包装导致的拆箱破损、损坏，其他破损、损坏的情况，展示板和膨胀聚苯乙烯与人工制品的粘连等。其他：水滴留下的污渍，标签绳结在粘合和修复部分留下的痕迹，文物本身的着色等。总共研究了9121件文物，发现其中约1475件发生了变化。在许多情况下，变化的因素是由于陈列和储存，而不是保存处理的问题。这些因素是值得注意的，保护科学研究人员和保护处理人员只要熟悉这些因素就可以解决。对于采用新工艺处理的木制品，在某些木制品表面化学试剂的分离方面仍有待进一步改进。然而，由于没有发现木制物品的尺寸变化，这表明文物本身长期稳定的现状得到了承认。

In this research, including information and photographs, collected from on-site research which had conducted over four years of secular change of artifacts on post-conservation treatment for current condition, were organized and compiled the database.It was remarkable the factors and the results of analysis from samples of artifacts which were found change from on-site research as follows :1.Processes of conservation treatment : Separation of chemical agents on wooden objects, reappearance of corrosion and cracking of metal objects due to defective corrosionproof, separation of calcium salt on resin-supplemented parts, and etc.2.Locations and circumstances of display/storage : Elution of chemical agents, appearance of blackening and stains due to high degree of humidity, decrease in function of conditioning dry and humidity agents, change of surface and color on artifacts, deterioration of supplemented resins, and etc.3.Handling : Breakage and damage during unpacking due to transporting and excess packing, other cases of breakage and damage, adhesion of display sheets and expanded polystyrene to artifacts, and etc.4.Others : Stains from water drops, traces by knots of label strings being off parts of adhesion and restoration, coloring on artifacts itself, and etc.About total 9,121 artifacts were researched and found change on about 1,475 of them. The factors of change were due to display and storage in many cases rather than a matter of conservation treatment. These factors are remarkable that it will be able to be solved by well familiarizing the factors to conservation science researcher and conservation processing staff.As for wooden objects treated with new processes are still expected further improvements in terms of separation of chemical agents on surface of certain wooden objects. However, since size change on wooden objects has not been found it shows that current status of long-lasting stability of artifacts itself were recognized.
