Cold Joining Wood Fittings to Raised Copper
起凸铜器与木质配件的冷结合
标签：冷连接, 铜木结合, 铆接, 可拆卸修复
起凸件的热敏感部位（壶把、盘足）可用木配件冷接：铜体锻出 Ø5–8 mm 柄芯或铆耳，硬木（黑胡桃、樱桃）钻孔后以环氧+黄铜铆钉双固定，含水率 8–12% 防日后开裂；热壶手柄选厚实硬木并垫云母片隔热。与传统锡焊相比，冷接不退火、不破坏锤纹与着色层，修复时还可拆卸，玉川堂与欧美金工工作坊均常见。接口打磨倒角后整体上蜡，木铜色差本身即是设计语言，浅色木随使用包浆渐深更有韵味。
Heat-sensitive areas of raised work (kettle handles, tray feet) take wood fittings by cold joining: forge a Ø5–8 mm tang or rivet ears into the copper, drill hardwood (black walnut, cherry) and fix with epoxy plus brass rivets, keeping wood at 8–12% moisture against later cracking; hot handles use thick stock with mica insulation. Unlike soldering, cold joins skip annealing, spare the hammer texture and patina, and stay removable for repair — common at Gyokusendo and Western workshops alike. Chamfer, wax the whole piece, and let the wood/copper contrast read as design: pale wood deepens with patina-in-use.
