Potassium nitrate/magnesium flash powder should be mixed and used immediately and not stored due to its tendency of self-ignition. If magnesium is not a very fine powder, it can be passivated with linseed oil or potassium dichromate. The passivated magnesium flash powder is stable and generally safe to store. 2 KNO 3 + 5 Mg → K 2 O + N 2 + 5 MgO
