Traditional gunpowder (also commonly called black powder) is made of carbon, sulphur and potassium nitrate (saltpeter), most recently and commonly in the ratio 15:10:75 respectively. However, gunpowder ceased to be a common propellant for firearms early in the 20th century.

Modern propellants are commonly known as smokeless powders rather than gunpowder, and are based on a combination of nitroglycerin, nitocellulose,and filler materials .
