Strontium nitrate Strontium nitrate Strontium nitrate is an inorganic compound made of the elements strontium and nitrogen with the formula Sr(NO). This colorless solid is used as a red colorant and oxidizer in pyrotechnics. Strontium nitrate is typically generated by the reaction of nitric acid on strontium carbonate. Like many other strontium salts, strontium nitrate is used to produce a rich red flame in fireworks and road flares. The oxidizing properties of this salt are advantageous in such applications. Strontium nitrate can aid in eliminating and lessening skin irritations. When mixed with glycolic acid, strontium nitrate reduces the sensation of skin irritation
Consumer fireworks smoldering compound as a powder compressed in a stiff paper tube. The most complicated method used to ignite consumer fireworks is to use electronic ignition. This is the preferred method of many professional pyrotechnicians worldwide because of the vast improvement in operator safety. There are a few electronic ignition (often called "e-fire") systems that use readily available materials. Laws regarding consumer fireworks vary between countries and states. In Finland, fireworks (other than novelties and sparklers) are usually sold between Christmas and New Years. It is legal to sell fireworks all year around (predominantly through online retailers).
