How beautiful are the fireworks?

The brilliant colors of fireworks come from adding different metal ions to the powder. When different metal ions burn, they show different colors of "flame reaction". Fireworks have different colors, such as purple potassium nitrate, golden sodium nitrate, orange-red calcium chloride and blue-green copper chloride.

When they emit light, their temperature can exceed 1000℃. It is at this high temperature that all kinds of special metal materials filled in fireworks can absorb enough energy and emit gorgeous light. It is precisely because different metal atoms can emit different colors of light at high temperature that fireworks can release different colors of fireworks.

Types of fireworks: There are many kinds of fireworks. According to the discharge effect, there are mainly 13 categories: flower spraying, spinning, spinning, rocket, bead spitting, small fireworks, smoke, modeling toys, combined fireworks, thread incense, friction guns, fireworks bombs and so on.
