Fireworks and a Chinese dragon: History of gunpowder

History of gunpowder: Fireworks

Who invented gunpowder?

Like the idea of zero, gunpowder developed gradually over time. In 142 AD, during the Han Dynasty, a man named Wei Boyang was the first to write anything about gunpowder. He wrote about a mixture of three powders that would “fly and dance” violently. We aren’t sure that he meant gunpowder, but that’s the only explosive that uses three ingredients that we know of. He may have been a Taoist trying to find a potion to let you live forever.

Ingredients of gunpowder

By 300 AD, a Jin dynasty scientist named Ge Hong had certainly written down the ingredients of gunpowder and described the explosion. Scientists made gunpowder in ancient China by mixing sulfur, charcoal, and saltpeter, or potassium nitrate. You got sulphur by mining it out of the ground, where it exists naturally as a yellowish rock. You could make potassium nitrate, or saltpeter, by taking animal manure and letting it sit around for a while and decay. Then potassium nitrate crystals formed in the manure, and you could drain them off by washing water through the manure pile. You mixed the three powders together, using about fifteen parts of saltpeter to three parts of charcoal and two parts of sulphur. The reason gunpowder explodes is that it burns very fast, and when it burns it releases gases that are bigger in volume than the original powder (just the way steam is bigger than water is).

Gunpowder leaves China

The Chinese emperors tried to keep gunpowder as a secret weapon, but by the 1100s AD their secret had gotten out, and people in the Islamic Empire and then the Roman Empire started to understand how to use gunpowder for weapons. After that, it wasn’t long before people in Europe also learned how to use gunpowder. Nobody is sure exactly how they found out, but it might have something to do with the Third Crusade.

By 1216 AD, a monk named Roger Bacon in England described gunpowder as a weapon. He thought of it as something that came from foreign places. Unfortunately for the people of West Africa, they hadn’t heard about gunpowder yet when European people attacked them in the 1400s AD, which is one reason why the Europeans were able to defeat them.

    Hey I was wondering if maybe you could post your sources on this. I am a UCLA student writing a final paper on gunpowder, it would be really helpful. Thanks!
