A few years ago, during winter time, I had a large citronella candle can in my room to take the edge off the chill.
The candle had burnt out and I was burning paper and bits of wax in the can. At some point I put hydrogen peroxide and bleach in the can as well. When everything burnt out I noticed green flames swirling around the inside of the can.
Basically what I'm wonder is what was burning to create green flame, and if I can recreate this effect.

I know that if you use barium nitrate as an oxidizer in a flash powder, it burns with a green flame. I do not know how you got a green flame. Maybe there was sodium hypochlorate in the bleach. I remember when i was a young pyro, I used to burn magazine covers, becuase they always made a green color, an to me that was fun.

I think any Barium salt will produce green even with a fuel, at least it did in Chem, i remeber magazine buring green, do you think they use Brium based inkes for that? If so how londg would it take to get enought for green smoke?

Well, I am not sure if there is any way you could get any barium out of a magazine, if a magazine doesnt have any already. I am pretty sure that any type of barium salt will produce a green flame.

Don't know how you got a green flame, but if you grind up copper and add it in a flash power, or with BP, it will turn the flame green.


Maybe it was in a copper container?

Only salts of copper would give any green off( copper nitrate, copper sulfate, copper chloride, copper chlorate,ect.).

nos nitrous oxide will make a green flame cause we made a flame thrower out of a car nitrous system and i shot a big green ball

Copper is generaly regarded as having a blue flame although, Copper, Barium, and Zinc all make a shade of green.

When using magnesium as the fuel, barium nitrate makes more of a dark green compared to the light green that zinc usually gives off. Copper make a medium blue.
