Zinc was largely used in manufacturing brass. It seems that there has been some confusion about early occurrences of zinc, brass and zinc extraction by distillation process. Brass, an alloy of zinc and copper, is known for a long time and can be produced accidentally as has been reported from China and West Asia.
