The Color of Fire
| May 18, 2011If you’ve ever stood beside a bonfire – or any kind of fire for that matter you’ve probably noticed that the flames are a gorgeous combination of colors. Ever wondered why? Well it all depends on what’s being burned. Any object that’s burned undergoes a series of chemical reactions. The energy produced from those reactions is given off as light or flames. The color of that flame depends on which chemicals are being burned. Most fires made from wood are a bright orange color because of the sodium in the wood. If there’s carbon and hydrogen burning you’ll see a bluish flame — if you have a gas stove you’ll know just the blue I mean. If there’s any trace of copper or copper products in the fire the flames will take on a gorgeous green color and if there is a lot of soot the flames will be a bright yellow. If you’ve made a bonfire from all kinds of objects (which can be very dangerous) you might get all kinds of different colored flames depending on the chemicals in the burning objects. But some chemicals give off not only colored flames but also poisonous fumes so be very careful what you put on a fire. What you can do is buy safe flame colorants using basic household items such as boric acid or table salt or buy them in special stores treat sawdust or pinecones with them and ask an adult to throw them in the fire from a distance for a colorful safe fire show!
