chemical formula: SiO2
( fluffy powder )
An anti-cake agent that makes powders stop clumping & flow evenly. In pyrotechnics, it is used in Flash Powder mixtures to increase the burn rate (typically 1 gram to every 100 grams of Flash Powder). This makes the Flash Powder "fluffy" allowing for much faster flame propagation. This material has virtually no weight to it, so it's sold by volume in a 4 ounce container.
