MudDuckPyro79 Posted June 19, 2022 Share Posted June 19, 2022 Got some 15 dollar bi203 from fwcb and tried the Chinese crackle micro stars formula and they are just smoldering for a bit then they will just poof like a strobe no pops at all. Copper oxide black 66 mg/also 200 mesh 28.5 and bi203 5.5 bound with 5 grams of double base and 2/3 cup acetone and screened thru an 8 mesh screen. They are very bright but no pop at all.

Carbon796 Posted June 19, 2022 Share Posted June 19, 2022 That is not a known published working crackle formula. It's just some B S made up shit. From a Chinese EX application form. It will never work, move on to a real crackle formula. Link to comment Share on other sites More sharing options...
MudDuckPyro79 Posted June 20, 2022 Author Share Posted June 20, 2022 I'm glad I only made 100 gram batch. I made the Lloyd comp couple years ago and it worked great. But then Ned gorski made a video of that comp using black copper oxide and it worked I asked him where he got it and said fwcb. Oh well I tried I'll make it like before with 71% bismuth.

Uarbor Posted June 22, 2022 Share Posted June 22, 2022 I just started making crackle and I am using the 37.5 / 37.5 / 25 formula 25 being magnalium. And it works fantastic. I'm using black copper oxide.https://youtu.be/dA1LipAsSms Link to comment Share on other sites More sharing options...
