A powder keg is a barrel of gunpowder. The powder keg was the primary method for storing and transporting large quantities of black powder up until the 1870s and the adoption of the modern cased bullet. However, the barrels had to be handled with care, since a spark or other source of heat could cause the contents to deflagrate.
