标签：配方, 肝硫, 使用, 古铜
经典配方：市售肝硫块/凝胶 **1–2 茶匙（约 5–10 g）溶于 1 杯（约 240 ml）60–80℃ 热水**，搅至澄清微黄。用法：工件彻底去油后浸泡、涂刷或热敷；30 秒至数分钟出棕→黑梯度，达色即取出。中和：浸饱和小苏打水停反应，清水冲净，干后打蜡。原液避光密封、现配现用（易氧化失效）。这是铜银器做旧最通用的配方。
Classic: 1–2 tsp (~5–10 g) commercial liver of sulfur in 1 cup (~240 ml) hot water at 60–80℃, stir to clear pale yellow. On degreased metal, dip, brush, or hot-pack; a brown→black gradient appears in 30 s–minutes, remove at target. Neutralize in saturated baking soda, rinse, dry, wax. Store stock dark and airtight; mix fresh (it oxidizes). The most universal antique recipe for copper and silver. ---
