What is the difference between gun powder and flash powder?

Gunpowder, primarily composed of potassium nitrate, charcoal, and sulfur, is used as a propellant in firearms and fireworks, providing a slower burn rate for controlled explosions. Flash powder, on the other hand, typically contains oxidizers like potassium perchlorate or potassium nitrate combined with a metal fuel like aluminum, making it highly sensitive and capable of producing a rapid flash and loud bang. While gunpowder is designed for sustained propulsion, flash powder is intended for quick, intense bursts of energy, often used in pyrotechnics and special effects. As a result, flash powder is much more dangerous to handle than traditional gunpowder.
