Dross production increases linearly by four times if the bath temperature changes from 880°F to 810°F (471°C to 432°C). At common temperatures used for galvanizing, dross is made of a mesh of zinc-iron alloy crystals encapsulated by molten zinc. Most dross drops to the bottom of the kettle because it is heavier than molten zinc.
