Green effect composition possible???

[Dragon99]

   Is this composition possible for green effect?

- Potassium chlorate: 50%

   - Barium carbonate: 25%

   - Charcoal: 15%

No, greenish yellow at best. 
 

You need a chlorine donor, or an additive that helps the chlorate to release chlorine, but the charcoal will destroy the green emission anyway. 

Charcoal can only be added in small amounts in green and blue flames, unless it is course and only contributes to a tail.

No it wont.

Also amount of barium carbonate is excess.

Sometimes lampblack or charcoal is added to red star formulations but its amount is very little.

I suggest not to play with chlorate.
