Product Information

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. Aluminium powder and potassium perchlorate are the only two components of the pyrotechnic industry standard flash powder. It provides a great balance of stability and power, and is the composition used in most commercial exploding fireworks.

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.Comment by AllakhazamIf I am not Mistaken, you can buy this from a tools and supply vendor in FreeWind Post in Thousand Needles. 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.

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. All ingredients used are FDA complaint for use in confections and candy as outline in FDA Code 21CFR73.350. Some flash powder formulations (those that use single-digit micrometre flake aluminium powder or fine magnesium powder as their fuel) can self-confine and explode in small quantities. This makes flash powder dangerous to handle, as it can cause severe hearing damage and amputation injury even when sitting in the open. Self-confinement occurs when the mass of the pile provides sufficient inertia to allow high pressure to build within it as the mixture reacts. This is referred to as 'inertial confinement', and it is not to be confused with a detonation. The composition is approximately 59% KNO 3: 31.6% Al: 9.4% S by weight for the reactants of the above stoichiometrically balanced equation.

A ratio of seven parts potassium perchlorate to three parts dark pyro aluminium is the composition used by most pyrotechnicians. Sizing Information for specific prodcuts can be found on the product description. For help sizing your edible creations, here are some useful links from NFD.
