市售三氯化铁按 1 份固体配 2–3 份水（质量比）配成约 38–42°Bé 溶液，温度控制在 25–35°C 蚀刻最快。切勿将水倒入浓溶液以免爆溅；佩戴耐酸手套与护目镜。

Mix commercial ferric chloride at 1 part solid to 2–3 parts water (by mass) to about 38–42°Bé; 25–35°C gives the fastest etch. Never pour water into the concentrate (it can splatter); wear acid gloves and goggles. ---
