khun2555 Posted March 23 Share Posted March 23 (edited) Can i use barium carbonate instead using barium nitrate to make green fire? Edited March 23 by khun2555 1 Link to comment Share on other sites More sharing options...
Zumber Posted March 23 Share Posted March 23 Barium nitrate itself is a oxidizer and can decompose with metals and chlorine donors to prodduce green fire but barium carbonate needs other oxidizers ( potassium perchlorate I dont mention other oxidizer as a begineer level) for its decomposition. Barium carbonate needs high temperature for its decomposition to produce oxygen. With other oxidizer and fuels ( metallic specially) it decomposes readily to produce green fire alongwith chlorine donors to improve colour intensity. -Zumber Link to comment Share on other sites More sharing options...
khun2555 Posted March 23 Author Share Posted March 23 Thanks, but how i can make green star with barium carbonate? Link to comment Share on other sites More sharing options...
Zumber Posted March 23 Share Posted March 23 If you are new to this hobby you might stop attempting colour stars first. Start with simple black powder related formulations first till you spend more time and get good experience and knowledge. Link to comment Share on other sites More sharing options...

Arthur Posted March 24 Share Posted March 24 Barium colours a flame green, strontium colours flame red, sodium colours flame yellow Nitrates supply oxygen to a flame, carbonates do NOT. SO barium nitrate fills two functions in a flaming star -colour and oxygen. Carbonates inhibit fire, so while barium carbonate is useful, you will have to find the flame's oxygen from something else Any star needs it's burning and it's effect designing into it. Stars can be from 1mm to 12mm diameter typically, not only must you make them, they must be strong enough to resist their launch to height.
