Conservation Standards: Reversibility & Repair Patina
文物修复着色规范与可逆性要求
标签：文物修复, 可逆性, 最小干预, 配色, 规范, 补配
文物修复着色遵循「最小干预、可逆性、可辨识」三原则：补配件颜色允许与原器有可辨识差异，仅要求远观协调。着色材料须可逆——禁用永久性染料与强腐蚀配方，常用弱硫化钾淡液（0.5 vol%）分多次薄涂 + 天然蜡封护，蜡层可溶剂去除。国际通行依据 ICOM-CC 与《中国文物古迹保护准则》，补色记录（试剂、浓度、层数）须归档入修复档案。
Conservation coloring follows minimal intervention, reversibility, and discernibility: repairs may remain distinguishable from the original, needing only visual harmony at distance. Reagents must be reversible — permanent dyes and aggressive formulas are banned. Standard practice is multiple thin coats of dilute potassium sulfide (0.5 vol%) sealed with natural wax, which solvents can remove. Follow ICOM-CC guidance and the China Principles, and archive the recipe, concentration, and coat count in the restoration record.
