<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->In 1597 AD, Libavius, a metallurgist in England received some quantity of Zinc metal and named it as Indian/Malabar lead.[61] <b>In 1738, William Champion is credited with patenting in Britain a process to extract zinc from calamine in a smelter, </b>a technology that beared strong resemblance to and was probably inspired by the process used in the Zawar zinc mines in Rajasthan.[62] <b>His first patent was rejected by the patent court on grounds of plagiarising the technology common in India. </b>However, he was granted the patent on his second submission of patent approval. Postlewayt's Universal Dictionary of 1751 still wasn't aware of how Zinc was produced.[63]  wiki/History_of_metallurgy_in_the_Indian_subcontinent<!--QuoteEnd--><!--QuoteEEnd-->
