Did China get knowledge about gunpowder from India?


New Delhi, November 13, 2020, Friday

Although the invention of fireworks is considered modern, people in ancient India were familiar with the type of fireworks that explode and spread fire. It is also mentioned in the economics of Kautilya in the East. Which describes a sulfur type powder that burns quickly in a fire. Putting this powder in the fire makes the light shine. Not so much if it explodes by filling it into a solid cylinder. A special type of salt that is finely ground into a quick-burning powder. Adding sulfur-type element and coal charcoal makes it more explosive.

Ammunition is generally believed to have been invented in China, but even 2,000 years ago, people in India knew about fireworks and gunpowder. It is believed that China also got knowledge about gunpowder from India. The Syrian chemist Hassan al-Rammah did this in his book in 150 AD. If we talk about the medieval history of India, even in the time of Mughals, Darukha was brewed. At Darashikoh's wedding in 18, a variety of firecrackers, including flowers and firecrackers, were blown up. However, Aurangzeb banned the burning of Darukhana on Diwali by associating it with the practice of Hinduism. Even when the British rulers came to India, the number of firecrackers on occasion increased.

On the one hand , we have a keen interest in chatting about nonsense in WhatsApp , but we are not particularly interested in knowing why fraud occurs , why it is avoided, etc. , so as not to lose our hard earned money in conversation .
