The resulting stable and reliable product, known as smokeless powder, was widely adopted in all types of guns in the following decades and supplanted black powder as the propellant charge in artillery and small arms ammunition.
Nitrocellulose propellants produce much less smoke and flash than black powder and deliver much more mechanical work per unit of weight. A fast burning rate is effective ballistically but tends to create excessive pressures in the gun barrel.
Each troop has hanging on him a little iron pot to keep fire [probably hot coals], and when it's time to do battle, the flames shoot out the front of the lance more than ten feet, and when the gunpowder is depleted, the tube isn't destroyed.

This is not sufficient for a mere hundred men, let alone a thousand, to use against an attack by the The other advantages of smokeless powder are its improved stability in storage, its reduced erosive effects on gun bores, and the improved control obtainable over its rate of burning.

Control of the burning rate is achieved by varying the compositionsize, and geometric shape of the propellant grains and sometimes by surface treatment or coating of the grains.
Most of the bulk semi-smokeless powders ceased to be manufactured in the s. This can rupture older weapons designed for black powder. In the s European chemists began adding special stabilizers to neutralize the residual acids and other decomposition agents in nitrocellulose.
