Flash Powder vs Black Powder in Fireworks

Fireworks come in all types of shape and size. While the packaging might look fantastic, its what the firework is made from that makes the difference. There are two types of powder that are used to power fireworks. Black powder which is a mixture of potassium nitrate, charcoal, and sulphur. Its the powder trail you see fizzing away in old western movies as the bad guy tries to blow up the Bank / mine / prison etc with a keg of gunpowder. Flash powder on the other hand is specially designed pyrotechnic composition consisting of an oxidiser and a metallic fuel, a common compound is Aluminium powder and potassium perchlorate. This is the chemical in those fireworks you can see in your neighbours gardens from several streets away.

To make sure you get the best quality fireworks for your money, try to buy flash powder based fireworks, these are easy to spot as the Government has a different classification for flash powder fireworks and black powder fireworks. Category 1.4G are black powder based and while pretty, lack the wow factor of your neighbours fireworks. 1.3G are the flash powder based fireworks, these are the ones that will amaze your audience. They are however usually noisier and do need more space to be fired safely. We have put together a guide to help you set off safe displays.
