Although fireworks have been invented a thousand years ago in China, they involve some very sophisticated science. So what is the secret behind the brilliant shapes and colors of those fireworks?
How are fireworks colors and shapes created?
The brilliant colors of fireworks are the result of metal compounds being oxidized. This produces heat, which transmits electrons in the chemicals to higher energy levels and then returns quickly to the normal state, which expels the energy in the form of light.
Strontium carbonate burning gives red color, sodium nitrate produces a yellow color, and barium chloride gives green. The most difficult color is the bright blue, which needs to reach a high degree of combustion, and companies often use copper chloride to get the correct temperature to show this degree of blue.
Stunning shapes are produced by including packages containing those chemicals that make the color in a particular order. Along with the explosion priming. Once the fireworks reach the right height, the fuse explodes and the gunpowder ignites and shows those shapes and colors that we know and love.

Interesting! Didn't know that blue flame requires most work.
Keep up good work!
Thanks :)
I always wondered how they work, thanks for posting!
No Problem :)
great information
good to know:)
