Beyond the formula itself, the process of making smokepowder was difficult and fraught with danger, often ending in an unplanned explosion. The United States Navy manufactured single-base tubular powder for naval artillery at Indian Head, Maryland, beginning in 1900. Chipotle powder is a chili powder with a mildly spicy heat that comes from smoked and dried jalapeno peppers. Alfred Nobel figure out how to take the unstable chemical and package it for use as an industrial explosive. Before the use of triple based propellants, the usual method of flash reduction was to add inorganic salts like potassium chloride so their specific heat capacity might reduce the temperature of combustion gasses and their finely divided particulate smoke might block visible wavelengths of radiant energy of combustion.

These additives can act a retardants which slow the burn of the grain, creating a harder to ignite but longer burning grain, or in the case of graphite, create lubricity preventing the clumping of the powder and allowing for uniform metering on loading equipment. If shellac is used it is necessary to raise the amount of Potassium Nitrate by 5 % to 10% (depending on how much shellac you use).A major step forward was the invention of guncotton, a nitrocellulose-based material, by German chemist Christian Friedrich Schönbein in 1846. The Navy licensed or sold patents for this formulation to DuPont and the California Powder Works while retaining manufacturing rights for the Naval Powder Factory, Indian Head, Maryland constructed in 1900.

g., bismuth trioxide, bismuth subcarbonate, bismuth nitrate, bismuth antimonide); the bismuth compounds are favored as copper dissolves in molten bismuth, forming brittle and easily removable alloy. This first powder was nearly entirely comprised of Nitrocellulose, but forever changed the propellent world.The gases expand but as they pass through the Mach disc, they are re-compressed to produce an intermediate flash. One of the advantages of Nitroguanidine is that is burns as a lower temperature, this reduces throat erosion, desirable for large caliber expensive cannon barrels. It should be noted though that Ed Greenwood stated in one tweet that smokepowder had completely different ingredients from gunpowder. In this propellant the fibrous structure of cotton (nitro-cellulose) was destroyed by a nitroglycerine solution instead of a solvent. In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material associated with black powder that causes rusting of the barrel.

Don’t ignite more than a tablespoon or two of the dried mixture at a time, and only use paper cups as containers, and of course don’t set it off were it could start a fire. The mixture was then fed through a press extruding a long tubular cord form to be cut into grains of the desired length. Smoke Bomb 12:
Titanium chloride 100%
Smoke Bomb 13:
Potassium nitrate 33%
Sugar 33%
Wax shavings 34%
Smoke Bomb 14:
Soak Ammonium Nitrate in water until it dissolves.

Place a lid on the large bowl and then wrap it with a plastic bag to allow the smoke to penetrate through the other ingredients. All the ash and tar are removed during the liquefaction process, leaving the liquid smoke pure and harmless to your health.
