Lloyds Buttered Popcorn - Antimony Sulfide OR Trisulfide

I "thought" I had all the ingredient to make this glitter from this thread:

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.

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.

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?

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.

The Antimony trisulfide deteriorates over time but not so fast .. a friend of mine lost a 20 kg can.
