《收藏投资导刊》:大部分拿来修复的作品都是哪些问题?不同问题的修复方法有哪些不同?张志红:送过来修复的书画作品大多数是因为保存不得当才出现了问题:有的梅雨季节受潮发霉,有的有水渍污渍,有的是在屋里挂的时间长了被烟熏了等等。归类来说近现代作品基本以人为损害的硬伤为主,有年代的作品则是损害的种
Collection Investment Guide: What are most of the works used to repair? What are the different methods of repair? Zhang Zhihong: Most of the paintings and calligraphy works sent to repair because of improper preservation problems: Some Rainy season damp moldy, and some water stains, and some hang in the house for a long time was smoked and so on. In terms of classification, modern works are mainly based on man-made damage, while works of the past are damaged
