Recording Standards for Rubbing Bronze Inscriptions
青铜器铭文捶拓的记录规范
标签：金石学, 铭文捶拓, 记录规范, 学术档案
学术性金文捶拓须随拓留档七要素：器物编号与藏地、拓制日期、拓工姓名、纸张（扎花宣/皮纸等）、墨法（乌金/蝉翼）、比例尺与方向标，拓片右下角钤"某某手拓"印。铭文区先以 5% 六偏磷酸钠棉贴敷清洗，忌硬刷伤锈；上纸用白芨水浓度不超过 3%——过浓日后揭纸会带落锈层。社科院考古所与各大博物馆均要求一器一档、拓本与照片同编号归档；拓片不得添加任何描修，字口残泐须如实拓出，学术价值即在于"存真"。
Academic bronze-inscription rubbings travel with a seven-item record: object number and holding institution, date, rubber's name, paper (zhahua xuan or pi paper), inking method (wujin or chanyi), scale bar and orientation, plus the rubbers' seal at lower right. Clean the inscription with 5% sodium hexametaphosphate poultices—never hard brushes on patina; size the paper with no more than 3% bletilla water, which lifts rust if stronger. CASS archaeology and major museums file one rubbing per object, numbered with its photographs, and forbid retouching—corrosion and breaks must print as they stand, for the value lies in truthfulness.
