sachinagg Posted May 12 Share Posted May 12 Bismuth trioxide have self life? I am trying to make White strobe- Barium nitrate -68 Almg-26 Bi2o3-3 Dextrin-3 I test my stars , not strobe but explode My bismuth trioxide is all most 10 yearsold.i have( 100gm +100gma+50gm) this type of packing, I used open packet which one I used 10 years ago. I think my bismuth trioxide in opened packet expired.colour also different opend and sealed packet. Any suggestions Link to comment Share on other sites More sharing options...
Zumber Posted May 12 Share Posted May 12 (edited) Your star must not have exploded Rather it could have given extreme strobing sound (like waving flag or birds wings movement) or pop sound ( nearly same as crackling but not that much loud as in crackling effect.) Remember stars behave differently in sky and ground so test star in shell /sky. This is normal in flash phase of strobe stars. If you test it in sky you will see the difference. Crackling star effect and strobing effect have almost equal theory and in crackling tremendous heat is developed suddenly which causes Magnelium to explode.

sachinagg Posted May 12 Author Share Posted May 12 Sound likes waving flag and pop(mix) sound, I will try in sky then I share what's going. And self life of bismuth trioxide? Thanks Link to comment Share on other sites More sharing options...
Zumber Posted May 12 Share Posted May 12 I think bismuth is good. Test it in sky. Most of problem in india now a days is bad quality of magnelium due to price rising for raw material (magnesium). Link to comment Share on other sites More sharing options...

I will try these stars in sky . I have bismuth trioxide that probably is 30 years old that works as new. It should of course be stored dry but that goes for all pyro ingredients.
