Selective Gilding in Contemporary Sculpture
当代雕塑的选择性贴金语言

当代雕塑家常把亮金用作"点睛"而非全覆盖：在化学着成黑褐的铸铜表面，仅对指尖、唇部或几何棱线贴 24K 金箔（3.3 cm × 3.3 cm/张），哑光黑底与镜面金形成强对比。关键在分界封护——先对整体喷 2K 聚氨酯底封，贴金后再局部罩光，金箔区选用 UV 恒定型清漆防脆化。单件雕塑用箔 50–300 张，材料成本可控而视觉溢价显著，已成为画廊级青铜作品的常见语言。
Contemporary sculptors use bright gold as accent rather than coverage: on chemically blackened bronze, 24K leaf (3.3 cm × 3.3 cm sheets) goes only on fingertips, lips or geometric ridges, mirror-gold against matte black. Edge control is critical—first a 2K polyurethane base coat overall, then leafing, then spot topcoat, using UV-stable lacquer on leaf to prevent embrittlement. At 50–300 sheets per sculpture, material cost stays modest while visual premium is large—now a gallery-bronze idiom. ---
