Gunpowder



Gunpowder is needed to make Combat Supplies and Landmines. Crafted in a Chemist Shop's, from Charcoal and Sulphur.

6 KNO3 + C7H4O + 2 S → K2CO3 + K2SO4 + K2S + 4 CO2 + 2 CO + 2 H2O + 3 N2

Gunpowder, also known as black powder, is a chemical explosive—the earliest known. Gunpowder was invented in China when Taoists attempted to create a potion of immortality. Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms. Gunpowder's burning rate increases with pressure, so it will burst containers but just burns in the open. Ignition of the powder packed behind a bullet must generate enough pressure to force it from the muzzle at high speed, but not enough to rupture the gun barrel. Gunpowder thus makes a good propellant, but is less suitable for shattering rock or fortifications. Gunpowder contains 3 megajoules per kilogram, and contains its own oxidant. For comparison, the specific energy of TNT is 4.7 megajoules per kilogram, and the specific energy of gasoline is 47.2 megajoules per kilogram (though gasoline requires an oxidant, so an optimized gasoline and O2 mixture contains 10.4 megajoules per kilogram). Gunpowder is a low explosive and as such it does not detonate; rather it deflagrates. Since it contains its own oxidizer and additionally burns faster under pressure, its combustion is capable of rupturing containers such as shell, grenade, or improvised "pipe bomb" or "pressure cooker" casings, forming shrapnel.
