Picture of Colored Flames

In this instructable i'll be showing you guys how to make multi-colored flames!
The flames turn green, blue and purple!

This is also great on a fireplace or campfire to bring out the true colors of fire!

When a metal or metal salt is burned, the input of thermal energy raises the electrons in the metal atom to a higher energy state. These electrons cannot remain in this excited state for too long and will emit energy in the form of light to return to the more stable, grounded state which is the light.

Step 1: Materials


1) Copper(ii) chloride (for blue color, i think it's also called cupric chloride)
2) Copper sulfate and borax (for green color... be careful with the copper sulfate; call a doctor if it gets in your eyes or you swallow it or if you keep it on your skin for too long; this is a very dangerous chemical)
3) Potassium chloride (for purple color)
4) Matches or a lighter
5) A fireplace with logs or a campfire (or just a piece of paper or something that can be lit)
6) Rubber gloves (don't forget, you're dealing with chemicals here!)
7) A bowl and a stirrer to mix the chemicals
8) A tissue (optional; only if you want to make a color bomb... which I know you do!)

All these chemicals aren't too hard to find, I got most of them from my old Chemistry teacher at my school (he was both surprised and glad that I asked him if he had any of these chemicals laying around!)

Step 2: Getting the chemicals


Collect all your chemicals and mix them together in a bowl.
Mix them thoroughly so each spot on the fire can get each color flames!
For a stirrer it doesn't really matter what you use, I used a pencil.

This is pretty cool. Sure beats using newspapers every time. You can find a chart that has all of the colors of the rainbow and the chemicals you need to create them. Just click on the link that I shared above. There's some good pictures where you can see the color of the flame change. Let me know if you need help! :)

Wow! Thanks for sharing this! The chart definitely helps in knowing which chemicals burn off different colors! :) Thanks again!
Your Welcome! I'm glad that you found it useful. It was a bit hard to find so I thought I'd share it here although you seem to have the "scientific" explanation behind the reaction hehe. Are you a Chem major?
akossoy (author)  Cheryl Khan9 months ago
No, I'm actually still in high school (senior)! Although I have always liked chemistry, I am going to major in computer science! :) Again, thanks for sharing the link!
Kudos to you. You have a bright future ahead of you!

could these chemicals be put into a candle?
if so do i just mix it in with the wax?
I think you should put the chemicals in the wick, not in the wax ( make a water solution and wet the string).
akossoy (author)  neozelandes2 years ago
sorry for taking so long to respond, i was never told when people commented on my videos for some reason so its hard to keep up. i suppose so as long as the wax isn't too hot that it burns the chemicals on the spot, good idea, i should try that!

another thing for blue would be magnesium powder... shouldn't be too hard to get if you have a pyrotechnics supply store around
Magnesium powder should burn a bright white. It is commonly used in the strobe style fireworks.

magnesium powder? will try!

can we see pics of the actual fire?
akossoy (author)  crossfire2 years ago
my fireplace broke and i haven't been successful in using other people's fireplaces! sorry about that.

akossoy (author)  GASSYPOOTS2 years ago

for green fire, ive mixed boric acid (roach killer) and some methl alchohol. works well, but makes white smoke that im pretty sure is poisonous
akossoy (author)  Terranan2 years ago
interesting, i should try that, as for the white smoke, i think it is poisonous so ill keep that in mind!
