Barium peroxide Barium peroxide Barium peroxide is the inorganic compound with the formula BaO. This white solid (gray when impure) is one of the most common inorganic peroxides, and it was the first peroxide compound discovered. Being an oxidizer and giving a vivid green colour upon ignition (as do all barium compounds), it finds some use in fireworks; historically, it was also used as a precursor for hydrogen peroxide. Barium peroxide is a peroxide, containing subunits. The solid is isomorphous to calcium carbide, CaC. Barium peroxide arises by the reversible reaction of O with barium oxide. The peroxide forms around 500 °C
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.
