In 1738, William Champion from the UK patented a commercial zinc smelting process, presenting it as a British metallurgical invention. This patent was granted despite the fact that British spies had previously copied the design from the long-established industrial operations at Zawar, Rajasthan. The patent allowed Champion to profit from a technology developed centuries earlier in India, with no credit given to its original innovators.

The Zawar Zinc Distillation, or ज़ावर ज़िंक, is a sophisticated metallurgical process for smelting zinc that originated in Rajasthan, India. Practiced since the 14th century, this method involved closed-retort downward distillation, a highly advanced industrial technique for its time. This process was crucial for producing pure zinc, a metal with significant applications, and was considered sacred due to its transformative nature and the specialized knowledge required.

The Story
In 1738, William Champion secured a British patent for commercial zinc smelting, marketing it as a novel "British metallurgical invention." This claim emerged during a period of intense industrial expansion, positioning the technique as a European innovation. The process, however, bore a striking resemblance to methods long established in India, raising questions about the true origins of Champion's patented technology.
The Zawar Zinc Distillation (ज़ावर ज़िंक) method, originating in Rajasthan, India, involved a sophisticated closed-retort downward-distillation process for zinc smelting. This industrial-scale production had been operational since the 14th century, predating European understanding of such techniques by centuries. The knowledge and practice were deeply embedded within local communities, representing not just a technological achievement but also a sacred craft passed down through generations, integral to the region's economic and cultural fabric.
The appropriation of the Zawar zinc smelting technique was later exposed through historical research, revealing that British industrial spies had copied the design directly from Indian practices. This act of industrial espionage allowed Champion to claim a patent for a process that was not his invention, effectively erasing the centuries of Indian innovation. The lack of acknowledgment for the original creators in Zawar highlighted a systemic pattern of biopiracy and intellectual property theft during the colonial era, denying credit and economic benefit to the originators.
Closed-retort downward-distillation zinc smelting was running industrially at Zawar, Rajasthan since the 14th century. British spies copied the design and claimed the patent.
