Finely powdered ferrocerium is a much more reactive fuel than magnesium and aluminium, and therefore mixtures with oxidizers tend to burn much faster than other flash powders. Reacts with magnesium when wet and liberates heat and ammonia, can self-ignite. This is one of the slower flash powders in use. Potassium permanganate in combination with magnesium or aluminium are exceptionally fast-burning flash powders. *Please select more than one item to compare NC lacquer (solvent) ...

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 mixture that hardly burns when the components have a certain particle size may explode violently with the particle size reduced to a tenth. - posted in Chemistry: so im completely new to the APC Sean. Flash powder using Potassium permanganate has gained a reputation for it's fierce and unpredictable reputation, and the many accidents caused by it means that it is never used in legal fireworks.
