sachinagg Posted May 12 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
Zumber Posted May 12 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. Edited May 12 by Zumber
sachinagg Posted May 12 Author 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
Zumber Posted May 12 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).
sachinagg Posted May 13 Author Posted May 13 Thanks for all, someone say that bismuth trioxide's self life is 36 months, if u make packing tightly than life will extended. I will try these stars in sky .
sachinagg Posted May 15 Author Posted May 15 Right now my strobe stars not explpde,they blink with huge sound

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.

Zumber Posted May 15 Posted May 15 Discussion has stared with crackling and turned to strobe thats why a bit confusion arises for me. Anyway no worries😀
