Gunpowder is a low explosive: it does not detonate, but rather deflagrates (burns quickly). This is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired.
Finnish smokeless powder. Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
The term gunpowder also refers broadly to any propellant powder. Modern firearms do not use the traditional gunpowder (black powder) described here, but instead use smokeless powder. Guncotton replaced black powder as a propellant, and was in turn replaced by smokeless powder. Gun serial number: A unique identifier given to a specific firearm.
The 19th and 20th centuries saw an acceleration in this evolution, with the introduction of the magazine, belt-fed weapons, metal cartridges, rifled barrels, and automatic firearms, including machine guns. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants.
The earliest gunpowder recipe and primitive weaponry date to China's Song dynasty and the oldest extant guns appear in the Mongol-led Yuan dynasty of China. However, historian Tonio Andrade notes that there is a surprising scarcity of reliable evidence of firearms in Iran or Central Asia prior to the late 14th century.
The oldest gun propellant was black powder, a low explosive made from a mixture of sulfur, charcoal, and potassium nitrate. It was invented in China during the 9th century as one of Four Great Inventions, and still remains in occasional use as a solid propellant for antique firearms.
In firearms and artillery, the primer (/ ˈ p r aɪ m ər /) is the chemical and/or device responsible for initiating the propellant combustion that will propel the projectiles out of the gun barrel. In early black powder guns such as muzzleloaders, the primer was essentially the same chemical as the main propellant (albeit usually in a finer ...
Cordite is a family of smokeless propellants developed and produced in Britain since 1889 to replace black powder as a military firearm propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance [not verified in body].
