Antique-finish Standards: Italian vs English Style
仿古做旧市场规范：意大利 Vs 英式
标签：市场规范, 意大利做旧, 英式做旧, 出口, 验收标准
出口仿古铜件的两大验收流派差异明显：意大利系（灯具、家具五金）要求"高光做旧"——硫化钾 0.8–1 vol% 一次浸黑后只对浮雕顶部抛光，覆盖率高但保留约 70% 亮面，色值以 Lab L* 35–45 验收；英式（古董复刻、军件）要求"深沉全黑"——肝硫两段浸（先 0.5% 后 2%），L* 20–28，缝内积色允许。混用标准是最常见的退货原因，接单前必须索取对方实物色板（master sample）。
Export antique finishing splits into two standards. Italian (lighting, furniture hardware) wants "highlight antique": one dip of 0.8–1 vol% K₂S to black, then polish only the relief tops — Lab L* 35–45 with ~70% bright surface. English (antique replicas, militaria) wants deep full black: two-stage liver of sulfur (0.5% then 2%), L* 20–28, with color pooled in recesses accepted. Mixing the two specs is the top cause of rejected shipments — always demand the client's physical master sample. ---
