Researches for Damages and Restoration of Contemporary Japanese Style

我们对二战后的当代日本风格绘画进行了研究，得出以下结论：最常见的问题是龟裂、脱落和跌落。有些画的问题是颜料涂得很重，并涂在金属叶子上。在一些作品中，问题的根源可能是艺术家作画的环境（尤其是过于干燥的条件）。在一些用细颗粒颜料和低浓度胶水的画上，我们发现了粉笔。我们注意到霉菌和“传真”。有些作品的复色层较薄，避免了朱砂和铜绿。银叶上出现变色和变色现象，朱砂叶上出现色素现象。银叶变黑的原因被认为是明矾被涂上了。在高温高湿环境下，朱红色层上的铅玻璃颜料（“shiniwaenogu”）变成硫化物而变色。在很多情况下，厚层画的修复是困难的。研制了厚层作品剥落修复机。

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.
