The composition is 62.5% KNO 3: 37.5% Mg by weight for the reactants of the above stoichiometrically balanced equation. Below is the same reaction but involving barium nitrate. No matter the quantity, care must always be taken to prevent any electrostatic discharge or friction during mixing or handling, as these may cause accidental ignition. Normally, flash powder mixtures are compounded to achieve a particular purpose. These mixtures range from extremely fast-burning mixtures designed to produce a maximum audio report, to mixtures designed to burn slowly and provide large amounts of illumination, to mixtures that were formerly used in photography.

Created by Pege Yates, a Sugar Artist & Mother of 5, to be a safe and edible option to add a flash of light to ANY edible creation. Lycopodium powder is a yellow-tan dust-like powder historically used as a flash powder. [1] Today, the principal use of the powder is to create flashes or flames that are large and impressive but relatively easy to manage safely in magic acts and for cinema and theatrical special effects. The composition is approximately 70% KClO 3: 30% Al by weight for the reactants of the above stoichiometrically balanced equation. Mixtures designed to make reports are substantially different from mixtures designed for illumination. A stoichiometric ratio of three parts KNO 3 to two parts Mg is close to ideal and provides the most rapid burn. The magnesium powder should be smaller than 200 mesh, though up to 100 mesh will work. The potassium nitrate should be impalpable dust. This mixture is popular in amateur pyrotechnics because it is insensitive and relatively safe as such things go. Flash powder compositions are also used in military pyrotechnics when production of large amount of noise, light, or infrared radiation is required, e.g., missile decoy flares and stun grenades.Different varieties of flash powder are made from different compositions; most common are potassium perchlorate and aluminium powder. Sometimes, sulfur is included in the mixture to increase the sensitivity. Early formulations used potassium chlorate instead of potassium perchlorate.

Note the shared oxidizer (A) powder for some types of fuels (B). Holds up reflective properties in hot sugar, candy work, isomalt, on chocolate, buttercream, fondant and more!

It is considered critically important to exclude sulfur and any acidic components from these mixtures. Sulfur oxidises and absorbs moisture to produce sulfuric and thionic acids; any acid in the mixture makes it unstable. Sometimes a few percent of bicarbonate or carbonate buffer is added to the mixture to ensure the absence of acidic impurities. A flash composition designed specifically to generate flares that are exceptionally bright in the infrared portion of the spectrum use a mixture of pyro-grade magnesium and powdered polytetrafluoroethylene. These flares are used as decoys from aircraft that might be subject to heat-seeking missile fire. For best results, "German Dark" aluminum should be used, with air float sulfur, and finely ball milled pure potassium nitrate. The finished mixture should never be ball milled together.Magnesium based compositions degrade over long periods, meaning the metallic Mg will slowly react with atmospheric oxygen and moisture. In military pyrotechnics involving magnesium fuels, external oxygen can be excluded by using hermetically sealed canisters. Commercial photographic flash powders are sold as two-part mixtures, to be combined immediately before use. If magnesium isn't a very fine powder it can be passivated with linseed oil or potassium dichromate. The passivated magnesium flash powder is stable and safe to store. Large quantities should never be mixed in a single batch. Large quantities are not only more difficult to handle safely, but they place innocent bystanders within the area at risk. In the event of accidental ignition, debris from a multiple-pound flash powder explosion can be thrown hundreds of feet with sufficient force to kill or injure. (Note: 3grams of mixture is enough to explode in open air without constraint other than air pressure.) A ratio of seven parts potassium perchlorate to three parts dark pyro aluminium is the composition used by most pyrotechnicians. The composition is approximately 59% KNO 3: 31.6% Al: 9.4% S by weight for the reactants of the above stoichiometrically balanced equation.
