The term black powder was coined in the late 19th century, primarily in the United States, to distinguish prior gunpowder formulations from the new smokeless powders and semi-smokeless powders. Semi-smokeless powders featured bulk volume properties that approximated black powder, but had significantly reduced amounts of smoke and combustion ...

More than 2.75 million pounds of first-quality gunpowder (a majority of the powder used by the Confederacy) were produced before its closure in 1865. [5] By comparison, Union gunpowder manufacture was distributed among many mills, with the larger Hazard Powder Company of Connecticut producing 40% of the annual production of 8.4 million pounds. [6]
The black powder contamination trapped on the magnetic separators is easily removed and stored in mineral bags. When the composition is primarily iron sulfides, there is opportunity for auto-ignition (smolders and flames), precautions must be taken to saturate the black powder with a chemical to neutralize it. Removing and monitoring the ...
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.
