The Zinc is the most interesting metal and was responsible for the invention of coins of mock gold and utensils of mock silver ad. Because of the low boiling point (907°C), zinc is difficult to smelt. Pure zinc can only be obtained after the mastery of distillation techniques, which have been described in our ancient chemical treatises. The mines have given definite evidence of the production of zinc from back to 6th Century BC in Rajasthan. The process of distillation was being used from the 12th century AD, So India was the first to produce zinc by using distillation processes. In fact, many ancient Indian literatures refers to various types of metal that were used in different periods. In the epics e.g. Mahabharata and Ramayana, brass and the bell metal have been termed as kamsya, the utensils of which were used for milking and drinking. The Rasaratnasamucchaya, a fourteenth-century alchemical text, tells that the Indian alchemy was not only confined to the principle of mercury and its compounds but also to a large number of other minerals. It reveals names of scores of celebrated alchemists like Nagarjuna, Govinda and others. The rasvidya (alchemy) was kept closely guarded secret and confined to devout practitioners only.
