Strontium carbonate a mineral, strontium carbonate is prepared synthetically in one of two manners. First of which is from naturally occurring celestine also known as strontium sulfate (SrSO) or by using soluble strontium salts by the reaction in solution with a soluble carbonate salt (usually sodium or ammonium carbonates). For example if sodium carbonate was used in solution with strontium nitrate: Sr(NO) + NaCO → SrCO + 2 NaNO . The most common use is as an inexpensive colorant in fireworks. Strontium and its salts emit a brilliant red color in flame. Unlike other strontium salts, the carbonate salt is generally preferred
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).
