浮雕完成后可硫化做旧：浸入硫化钾（1%–3%）溶液数秒至数分钟得棕黑层，水洗后软布抛光高光。封护三选一：热熔蜡（家具蜡）薄涂、BTA 钝化后清漆、或电泳涂层。户外件优先电泳+定期重涂，避免绿锈蔓延。

After embossing, sulfide-patinate: dip in 1%–3% potassium sulfide for seconds to minutes for a brown-black layer, rinse and buff the highs with a soft cloth. Seal by one of three: thin hot wax (furniture wax), BTA passivation then clear lacquer, or electrophoretic coat. For outdoor work prefer the e-coat with periodic recoating to stop green corrosion spread.
