Barium nitrate Barium nitrate Barium nitrate is the inorganic compound with the chemical formula Ba(NO). It, like most barium salts, is colorless, toxic, and water-soluble. It burns with a green flame and is an oxidizer; the compound is commonly used in pyrotechnics. Barium nitrate is manufactured by two processes that start with the main source material for barium, the carbonate. The first involves dissolving barium carbonate in nitric acid, allowing any iron impurities to precipitate, then filtered, evaporated, and crystallized. The second requires combining barium sulfide with nitric acid. It occurs naturally as the very rare mineral "nitrobarite". At elevated temperatures, barium
Consumer fireworks Consumer fireworks Consumer fireworks are fireworks sold to the general public for use. They are generally weaker in explosive power compared to professional displays. Consumer fireworks are often quite small and can be classified into three groups: daytime, nighttime, and novelty fireworks. Daytime fireworks include most bottle rockets, smoke balls, firecrackers, and other fireworks that emit very little or no light. Some examples of daytime consumer fireworks include: Novelty fireworks typically produce a much weaker explosion and sound. In some Countries and areas where fireworks are illegal to use, they still allow these small, low grade fireworks to be used.
