Black powder substitutes can be transported and stored in interstate commerce in the United States using the smokeless powder regulations instead of the more restrictive black powder regulations. As a result, black powder substitutes are becoming more commonly available than traditional black powder.
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.
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].
When the extract is used to fight black mold, the acids continue penetrating growth and prevent mold spores from returning. Mix about 10 drops of grapefruit seed extract oil to every 1 cup of ...

More-stable and slower-burning collodion mixtures were eventually prepared using less concentrated acids at lower temperatures for smokeless powder in firearms. The first practical smokeless powder made from nitrocellulose, for firearms and artillery ammunition, was invented by French chemist Paul Vieille in 1884.
Modern firearm propellants tend to be smokeless powders based on nitrocellulose or similarly nitrated organic compounds, first invented in the late 19th century as a cleaner and better-performing replacement for black powder. Modern smokeless powder may be corned into small spherical balls, or extruded into cylinders or strips with many cross ...
An FDA investigator also observed a “black mold-like substance” at the base of a hose reel and behind a water storage tank at the facility, which was within a foot away from equipment used for ...
