Researches for Damages and Restoration of Contemporary Japanese Style

对二战后的时代背景下的当代日本风格绘画进行了研究，认识到了以下几点。最常见的问题是裂缝、剥落和坠落。麻烦的是，一些画上的颜料画得很重，并铺在金属叶子上。在一些作品中，问题的根源可能是艺术家画画的环境(特别是在干燥的条件下)。在一些颜料颗粒细小、胶水浓度较低的画上，我们发现了粉化现象。我们注意到霉菌和“传真”。一些作品上有薄薄的一层，避免了朱红和粉刺。银叶变色变色，朱红色素变色。银叶发黑的原因被认为是明矾被涂上了油漆。在高温高湿的环境中，朱红层上的铅玻璃颜料(“新外古”)会变成硫化物而变色，在许多情况下，厚层绘画的修复是困难的。我们生产的修复机用于厚层工程的剥离。

We researched on contemporary Japanese style painting on the times after World War 2 and recognized the following.a. Most popular troubles were cracks, exfoliation and falling. That trouble on some paintings that pigments were painted heavily and laid on metal leafs.b. On some works, the source of the trouble may be surroundings (especially over dry condition) that artists made the paintings.c. On some paintings with fine particle pigments and low concentration of glue, we found out chalking.d. We noticed mold and "faxing". Foxing on some works had thin layer avoided vermilion and Verdigris.e. The discoloration and change of color were occurred on silver leaf and pigments on vermilion. The cause of Blackened silver leaf is supposed that alum was painted.f. In surroundings of high temperature and high humidity, lead glass pigments ("Shin-iwaenogu") on vermilion layer changed to sulfide and become discolored.In many cases, the restoration of paintings with thick layer is difficult. We produced restoration machine for exfoliation of thick layer works.
