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.
Earliest known written formula for gunpowder, from the Wujing Zongyao of 1044 AD.. Gunpowder is the first explosive to have been developed. Popularly listed as one of the "Four Great Inventions" of China, it was invented during the late Tang dynasty (9th century) while the earliest recorded chemical formula for gunpowder dates to the Song dynasty (11th century).

Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder. The combustion products of smokeless powder are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate , potassium sulfate , and potassium sulfide ) for black ...
The entries are grouped according to their uses, with rough classes set aside for very similar weapons. Some weapons may fit more than one category (e.g. the spear may be used either as a polearm or as a projectile), and the earliest gunpowder weapons which fit within the period are also included.
Gunpowder, the first explosive, is developed. [1] [2] 1040 - 1044 The book Wujing Zongyao contains three formulas for gunpowder, the first such reference. 1267 Roger Bacon's Opus Majus contains the first European reference to gunpowder. [3] 1659 Ammonium nitrate is first synthesized by Johann Rudolf Glauber; it wasn't used as an explosive until ...
The grain is the traditional measurement of the weight of bullets, black powder and smokeless powder in English-speaking countries. It is the unit measured by the scales used in handloading; commonly, bullets are measured in increments of one grain, gunpowder in increments of 0.1 grains. [12] There are 7,000 grains in one pound.
This is a timeline of the history of gunpowder and related topics such as weapons, warfare, and industrial applications. The timeline covers the history of gunpowder from the first hints of its origin as a Taoist alchemical product in China until its replacement by smokeless powder in the late 19th century (from 1884 to the present day).
