NeighborJ Posted December 19, 2016 Share Posted December 19, 2016 Hey Tex, I'm giving your formula a go. I've tried similar formulas but only using them in the winter when humidity is low. This time I've replaced the dex and a small amount of the charcoal with Phenolic resin resin and disolved it in alcohol. If I like the formula, I'll save some for use in the summer so I can see how it stores. The video looks nice, similar to Lloyd's buttered popcorn when made with MgAl instead of AL(my favorite).

Pirotex Posted December 19, 2016 Author Share Posted December 19, 2016 Charcoal compositions works bad with ethanol and phenolic resin.. Link to comment Share on other sites More sharing options...
NeighborJ Posted December 19, 2016 Share Posted December 19, 2016 Yeah your absolutely correct, but I prefer to say that the Phenolic works but it changes the effect-expecially with glitters. The comets are pressed and in the drying box. It's worth a try because otherwise in my climate the stars go stale. The resin tends to not release the metal or charcoal during the burn and ends up being a big clump of char. In the past I've added DE micro stars to force the glitter and charcoal from the surface. This may be the only option for me. It's a compromise. Link to comment Share on other sites More sharing options...

Ubehage Posted December 20, 2016 Share Posted December 20, 2016 Can this composition be rammed instead of pressed? 1 Link to comment Share on other sites More sharing options...
OldMarine Posted December 20, 2016 Share Posted December 20, 2016 (edited) It's a charcoal based comp with no sparking metal so I see no reason it can't be rammed, especially if dampened. I am wondering how hard it is to get dry. Edited December 20, 2016 by OldMarine 2 Link to comment Share on other sites More sharing options...

dynomike1 Posted December 24, 2016 Share Posted December 24, 2016 (edited) What size were those stars, since they burn so long? I wonder if you could substitute Phenolic for Dextrin? Edited December 25, 2016 by dynomike1 1 Link to comment Share on other sites More sharing options...

NeighborJ Posted December 25, 2016 Share Posted December 25, 2016 Mike, I tried the Phenolic, it didn't work. The sodium nitrate wasn't aggressive enough and it burned like a chunk of wood. Link to comment Share on other sites More sharing options...

OldMarine Posted December 25, 2016 Share Posted December 25, 2016 I guess I'll have to pry my wallet open and order some NaNO3 and some more silica gel. I've got to try this glitter.I may try using the same comp as a delay in my rocket rather than my usual Win 39J. Link to comment Share on other sites More sharing options...
NeighborJ Posted December 25, 2016 Share Posted December 25, 2016 OM, try Lloyd's popcorn with coarse MgAl instead of fine AL. It looks identical and works for rocket delays. Link to comment Share on other sites More sharing options...
OldMarine Posted December 25, 2016 Share Posted December 25, 2016 Yeah, I like that idea better because I can store my rockets longer without that hygroscopic delay in there. Link to comment Share on other sites More sharing options...
