Contemporary Jewelry Brands: Small-batch Electro-gradient Coloring
当代首饰品牌的小批量电解渐变着色

欧洲多家独立首饰工作室把电解着色做成签名语言：恒电位仪控制下以 0.3–0.8 V 阶梯递增、每级停留 30–60 s，硫化铜膜由金褐、紫红渐入蓝黑，同一吊坠呈现干涉渐变。相比火法与浸煮法，电解膜厚重复性达 ±5 nm 量级，适合 50–200 件小批量一致性控制；工作室据此发布"色号卡"并公开电压-时间曲线，把工艺参数转化为品牌卖点与客户复购理由。
Independent European jewelry studios treat electro-coloring as a signature: under potentiostatic control, voltage steps of 0.3–0.8 V held 30–60 s each move a cuprous sulfide film through gold-brown, purple-red and blue-black, giving one pendant a full interference gradient. Film-thickness repeatability of ±5 nm suits 50–200-piece batches; studios publish "color-number cards" with voltage-time curves, turning process parameters into brand equity. ---
