Case: Restorative Planishing of an Antique Copper Kettle
案例：古铜壶表面的修复性打平
标签：文物修复, 局部打平, 包浆保护, 低力度, 专家复核
一件清代铜壶因磕碰出现多处凹陷与陈旧锤痕。修复时先拍照建档，仅对变形区做局部退火（用小块木炭控温，避免整体氧化），再用小号蛋形砧配轻木锤小心补打，尽量保留原有包浆。每步前后对比照片，交文物专家复核后再进入封护工序，禁止为求平整而过度打磨破坏历史层。
A Qing-dynasty kettle showed dents and old hammer marks from knocks. We documented it photographically, then locally annealed only the deformed areas (controlled heat with a small charcoal piece to avoid overall oxidation) and carefully re-planished with a small egg stake and light wooden mallet, preserving the original patina. Photos were taken before and after each step and reviewed by a conservator before sealing—over-grinding the historic layer was forbidden. ---
