Features: The gunpowder we refer to generally refers to the earliest "black gunpowder" used by people. It is a substance that can be ignited by sparks, flames, or igniting devices, and can undergo rapid and regular combustion without the participation of external oxidizing agents. Due to the large amount of gas and heat released during the combustion of gunpowder, it is often used as the energy source for weapon. Gunpowder is also known as "propellant" in military applications. The invention of gunpowder is closely related to alchemy. Ancient alchemists did not create the "immortal elixir" for the emperor, but accidentally invented gunpowder. Later, gunpowder sparked great interest among ancient Chinese military strategists. Through relentless efforts, they finally mixed niter, sulfur, and charcoal in a certain proportion to create the world's earliest gunpowder. Gunpowder became one of the Four Great Inventions of ancient China.
