usapyro Posted June 16, 2017 Share Posted June 16, 2017 (edited) I'm looking for a max candlepower KClO4 formula for use in comets and released from rockets at apex. Originally, I was thinking standard 'F' with bright aluminum and bound with like 5% NC to prevent it from containing. Primed with Si/KNO3. I could also use PVC as a binder. The container is still sealed, not sure what dissolves it. Acetone? But, wouldn't you get a bit more candlepower for the weight by using less oxidizer and letting some molten aluminum slough off and use the oxygen in the air to burn? I was also thinking magnalium might put out more candlepower. Edited June 16, 2017 by usapyro Link to comment Share on other sites More sharing options...
OldMarine Posted June 16, 2017 Share Posted June 16, 2017 The #2 Spanish white works great and doesn't contain barium. Link to comment Share on other sites More sharing options...
MadMat Posted June 16, 2017 Share Posted June 16, 2017 I don't know how it stacks up against other comps for all out candle power, but Shimizu silve wave #2 is pretty dam bright and it's a simple comp to boot. The only problem I found with it is the dex has to be increased to 7-8% to get useable hardness. Link to comment Share on other sites More sharing options...

These can burn fierce if under bound so 8% is a good place to start.For really really bright, but a bit faster, sub half of the bright alum with dark indian german 5413 etc. and use 8% dex. Using NC to help bind for the reason you described I can't say, haven't tried that yet. You can do quite few different tweaks with shimizu silver waves. You can sub in magnal like the dark alum ratio with 50% 200 mesh granular for a fatter looking flame envelope. For a longer tail then use 50% bright and 50% spherical like alcoa 120. For even longer and brighter tail then use 50% bright, 25% dark alum and 25% spherical titanium 50-150 mesh. I actually use those ratios for real. So if your going to try the #2, 60P/40A, split the 40 with those %'s. Edited June 17, 2017 by Sparx88 Link to comment Share on other sites More sharing options...
