stix Posted February 11, 2018 Posted February 11, 2018 (edited) I "thought" I had all the ingredient to make this glitter from this thread:http://www.amateurpyro.com/forums/topic/7018-buttered-popcorn-glitter/ After mixing all the ingredients, and doing a double-check, I've realised that the composition calls for Antimony Sulfide, not Trisulfide. I've done some research and it "seems" they are the same thing, but I haven't read anything that is definitive. What I have and what I've used in other glitter comps (successfully) is Antimony Trisulfide (Chinese Needle). It's black and -325 mesh. Edited February 11, 2018 by stix
Mumbles Posted February 11, 2018 Posted February 11, 2018 They're the same thing. There is another sulfide but easy to recognize. It's a yellow-ish gold compound. It's colloquially called antimony pentasulfide, but that's a misnomer. It's still antimony trisulfide, but absorbs and interrelates extra sulfur. It's still antimony +3. I don't know what I mentioned this as it's not commonly available. Long story short, you're good. 1
stix Posted February 11, 2018 Author Posted February 11, 2018 (edited) Cheers Mumbles, much appreciated. One more question It was also mentioned in that above thread that it's sensitive to shock. That was in relation to someone asking if it was ok to use for ramming a rocket motor using a metal spindle. Regardless, It did make me concerned. My usual mode of operation for compositions I'm testing, is to make a small mix (40grams) cut some 1/4" stars and make 2 comets. The comets are ram pressed, ie. I use a 17mm ID copper tube with a wood dowel and hammer press - medium to heavy pounding to ensure a dense slug. Now I'm thinking that this is perhaps not a good idea?

OldMarine Posted February 11, 2018 Posted February 11, 2018 I've rammed 1" comets with this comp with no problems. I do use a disc of chipboard on top of the comp to keep it from creeping up between the plunger and body of the pump.That may not be necessary but I do it on all comets now as a habit. 1
kleberrios Posted February 15, 2018 Posted February 15, 2018 The Antimony trisulfide deteriorates over time but not so fast .. a friend of mine lost a 20 kg can.
