Maxim-Schupphaus smokeless powder

Maxim-Schupphaus smokeless powder was the first of its kind developed in the United States and adopted by the U.S. government. Invented by Hudson Maxim and R.C. Schupphaus, it was a significant advancement in explosives technology.1

This type of powder is a nitrocellulosic explosive, meaning it is derived from nitrocellulose, also known as guncotton. While early attempts at using guncotton as a propellant were too violent, chemists like Major E. Schultze in the Prussian army developed more controlled nitrocellulosic propellants by nitrating wood and impregnating it with nitrates. Paul Vieille later created the first modern smokeless powder by dissolving nitrocellulose in ether and alcohol, forming a gelatinous mass that dried into a hard material.23

Smokeless powders, including Maxim-Schupphaus, produce significantly less smoke than traditional gunpowder, offering advantages in terms of visibility and reduced fouling in firearms. They are generally more stable and provide higher muzzle velocities compared to black powder.4
