About this deal

The combination of aluminium powder and potassium chlorate is unstable, and a poor choice for flash powder that is to be stored for more than a very short period. For that reason, it has been largely replaced by the potassium perchlorate mixtures. Chlorate mixes are still used when cost is the overriding concern because potassium chlorate is less expensive than perchlorate.

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. 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. Sizing Information for specific prodcuts can be found on the product description.

We DO NOT USE artificial coloring such as FD&C Red 40, FD&C Blue 1, FD&C Blue 2, FD&C Yellow 5, FD&C Yellow 6, Carmine or other synthetic coloring.Screenshots containing UI elements are generally declined on sight, the same goes for screenshots from the modelviewer or character selection screen.

Photographic Times and American Photographer, vol.18. Scovill Manufacturing Company. 1888. p.26 . Retrieved 23 October 2017. 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. 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.

( November 2013) A ratio of seven parts potassium perchlorate to three parts dark pyro aluminium is the composition used by most pyrotechnicians.


For best results, the aluminium powder should be "Dark Pyro" grade, with a flake particle shape, and a particle size of fewer than 10 micrometres. The KClO 4 should be in powder form, free from clumps. It can be sieved through a screen, if necessary, to remove any clumps prior to use. The particle size of the perchlorate is not as critical as that of the aluminium component, as much less energy is required to decompose the KClO 4 than is needed to melt the aluminium into the liquid state required for the reaction.

The composition is approximately 59% KNO 3: 31.6% Al: 9.4% S 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.
