Raising Repairs in Silver Conservation
银器修复中的起凸补配与锤痕匹配

修复古银器缺损时，补片需与原壁厚一致（测厚仪多点取值，常见 0.8–1.2 mm），退火至 650℃ 暗樱红色后水淬软化，再在窝砧上起出贴合曲率。判断原作锤序靠斜光观察锤痕重叠方向与排布节奏，新补片锤痕须主动匹配而非重新满锤。补片用银钎料（650–720℃）低温点焊或以银胶可逆固定，最后整体做旧统一光泽。
When filling losses on historic silver, the patch must match the original wall thickness (measured at multiple points; typically 0.8–1.2 mm), annealed at 650°C to a dull cherry red and water-quenched soft, then raised on a stake to the local curvature. Read the original hammer sequence under raking light — overlap direction and rhythm — and actively match the new patch's marks rather than re-hammering the whole field. Attach patches with low-temperature silver solder (650–720°C) spot joints or reversible silver paste, then age the whole surface to one tone. ---
