NeighborJ Posted December 19, 2016 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 Posted December 19, 2016 Charcoal compositions works bad with ethanol and phenolic resin..
NeighborJ Posted December 19, 2016 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.
memo Posted December 19, 2016 Posted December 19, 2016 I like those stars pirotex, going to give them a try
Ubehage Posted December 20, 2016 Posted December 20, 2016 Can this composition be rammed instead of pressed? 1
OldMarine Posted December 20, 2016 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
sumagg27 Posted December 20, 2016 Posted December 20, 2016 Hello Tex,if I use 100 mesh mgal than glitter effect will be not same as u show in your video because I hav't 50to70 mesh.I liked your glitter effect its to good
Pirotex Posted December 20, 2016 Author Posted December 20, 2016 Hello Tex,if I use 100 mesh mgal than glitter effect will be not same as u show in your video because I hav't 50to70 mesh.I liked your glitter effect its to goodWorks only with coarse magnalium
DavidF Posted December 20, 2016 Posted December 20, 2016 That was such a beautiful rocket and shell. The glitter was truly amazing. Two thumbs up!
sumagg27 Posted December 23, 2016 Posted December 23, 2016 Some one try this effect with coarse aluminium? I like this glitter but coarse mgal is not available.Thaks
dynomike1 Posted December 24, 2016 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
August Posted December 25, 2016 Posted December 25, 2016 If you are in the states, I have 30-60 and 60-100 MgAl available.

NeighborJ Posted December 25, 2016 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.
OldMarine Posted December 25, 2016 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.
NeighborJ Posted December 25, 2016 Posted December 25, 2016 OM, try Lloyd's popcorn with coarse MgAl instead of fine AL. It looks identical and works for rocket delays.
OldMarine Posted December 25, 2016 Posted December 25, 2016 Yeah, I like that idea better because I can store my rockets longer without that hygroscopic delay in there.
dynomike1 Posted December 26, 2016 Posted December 26, 2016 I wonder what that star would look like in a shell of shells?
