Barium chlorate in some sodium contamination, which is undesirable for pyrotechnic purposes, where the strong yellow of sodium can easily overpower the green of barium. Sodium-free barium chlorate can be produced directly through electrolysis: It can also be produced by the reaction of barium carbonate with boiling ammonium chlorate solution: The reaction initially produces barium chlorate and ammonium carbonate; boiling the solution decomposes the ammonium carbonate and drives off the resulting ammonia and carbon dioxide, leaving only barium chlorate in solution. When exposed to heat, barium chlorate alone will decompose to barium chloride and oxygen: Barium chlorate is used to produce chloric
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.
