Non Toxic Colored Flare Formulas?

Recommended Posts

Hello I am looking to make some safe non toxic formulas for colored flares. I am pretty sure while searching google somewhere I have heard of some non toxic versions but when re-searching could not find them again. If you guys/gals could help me with some non toxic color flares formulas I would really appreciate it. I am looking to make different colors for for mini flares project. Are there non toxic formulas or am I just thinking that I saw them? I could swear I have seen something somewhere about this..?

 

Green

Red

Yellow

Gold

Purple

Magenta

Blue

White/SIlver

Lol, yeah that is kind of what I had figured, I just wanted to know if there was such a thing. What I meant to say was "Less Toxic" not non toxic, but this means that I will need to break down each color formula first and analyze them.

 

Thanks anyway..

Basically any formulations that NOT contents, Barium Nitrate (or any barium salts), sodium oxalate, antimony trisulfide, cupper salts or oxides, and the obviously lead, mercury, and arsenic compounds.

 

This allows as options, red of strontium salts, yellow of sodium salts or cryolite, metallic white (except metalic flakes), charcoal based gold, and sorry.. but NO green, blue or they hibrids.

 

All this referring to a INGESTION.

The fortunate part being that no-one requires tests on fireworks for being eaten, only the fumes may be harmful, even then some nominally harmful comps can be safe at a distance. If you have 100g of paris green stars at 500ft high then the arsenic at ground level will be very slight. Would I use paris green in a parade torch -probably not, as someone would be holding it at arms length.

You can probably find some green formulas using Barium Sulfate. It's about the only safer form of barium due it not being soluble in stomach acid.

Could you give some examples of toxic fumes created by colored fires?
