Sugar Nitrate Smoke Composition

General Information | Low Order / Smoke

AKA: KNO3/Sucrose smoke, candy smoke.
Appears: Hard and brittle white or brown mass. Generally slightly sticky, even when hardened.
Formula: KNO3 + C12H22O11
Stability: Stable.
Sensitivity: Flame and high temperatures associated with fire. Ignites at perhaps 250° C.
Solubility: Water.
Velocity: N/A



   Sucrose ( C12H22O11 ) 40
   Potassium Nitrate ( KNO3 ) 60
   Sucrose ( C12H22O11 ) 30
   Potassium Nitrate ( KNO3 ) 70
     In a metal pot or other vessel, mix both ingredients (as dry powder) and heat until melting begins to occur. The sucrose will melt first, caramelizing in the process and turning brown. At this point, stir intermittently to keep the mixture from sticking to the sides of the pot and keep it moving often enough to keep it from burning. Ignition over a well controlled heat source is possible, but unlikely. This is best done over an electric burner. At any sign of smoking, blackening, or flame you should remove the pot from the heat and remove yourself from the area in case of ignition. Once the ingredients are thoroughly mixed and melted, scrape the resulting gunk into a container until it cools.
    Upon cooling the material will harden into a brittle substance. During the cooling process fuses, matches, or other ignition devices may be inserted and will be firmly held in place as the composition forms around, cools, and hardens. Once cooled the composition can be removed from the container, as it will hold its shape. The composition is hygroscopic, but the effect of this is minimal since air (and the moisture in it) can only get to the outer surface of a hardened mass of the compound. Powdered product will feel this effect quite severely, however, and must be stored accordingly.
    Sugar nitrate compound dissolves in water, by the way, so cleaning up your equipment after making a batch of the stuff is as simple as dunking it in the sink.


    Sugar nitrate composition can be lit with a simple flame, fuse, or electrical igniter. Ignition from environmental temperature is very unlikely, except in quite extreme conditions. Upon ignition the material burns with an intense orange or purplish flame and produces copious amounts of white smoke. At sea level this smoke will rise to an altitude of perhaps twenty feet, settle back to the ground as it cools, and eventually dissipate. This composition burns with intense heat - It may damage or set alight the surrounding scenery.


    This compound burns with an extremely hot flame. Contact with the burning compound should quite obviously be avoided.
    The smoke from this composition is toxic. Care should be taken to avoid excessive inhalation. Inhaling too much of any smoke can be harmful and cause respiratory damage.
    Not toxic if swallowed in reasonable amounts.
    If possible, store in an airtight container in a cool environment. Avoid extreme heat and flame.
