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