摘要 胶矾水在书画创作、书画装裱以及古籍修复中是常用的配料。胶矾水的主要功能是防墨洇散,防水固色,除此之外还可加固、防腐。一方面,胶矾水中的明胶可以填充纤维间隙,包覆纤维,起到防墨渗入的作用;另一方面,明矾有"架桥"和"絮沉"作用,优化明胶性能、助留墨迹。但由于胶矾水中明矾的水解作用导致纸张酸化、劣化,因此尽量避免添加明矾或亟待寻找胶矾水的替代品,达到既能防洇散又对纸张无损伤的效果。 Gelatin and alum water is a common ingredient in the creation and mounting of calligraphy and painting as well as ancient books repair. The main function of gelatin and alum water is to prevent ink from bleeding, resist water and fix color. In addition, it can also strengthen paper and prevent corrosion. On the one hand, gelatin can fill the fiber gap and coat the fiber to prevent the ink from penetrating. On the other hand, alum has the functions of “bridge” and “flocculation” to optimize the gelatin performance and retain the ink. However, due to the acidification and deterioration of the paper caused by the hydrolysis of alum, alum had better be avoided or a substitute for gelatin and alum water should be found, so as to prevent ink from bleeding and do no harm to paper.
