Non-toxic "traffic light" BaSO4 Green.
Posted 05 July 2008 - 03:17 PM
Composition Type: Star.
Creator: Troy Fish (I think)
Color/Effect: emerald green with slight yellow/orange spark trail.
The Composition: (by weight)
Barium Sulfate 35
Potassium Perchlorate 30
Magnalium, granular, -325 mesh 10
Red Gum 5
Any Precautions/Incompatabilities: Contains a Sulfate, do not combine with Clorates.
Precedure/Preparation: I got this from Passfires formulas and it says to bind with 50/50 acetone/alcohol, but I used just acetone straight from the can, you could also use MEK for a longer workability time, and could probably drop the Red Gum if not useing alcohol (I left it in)
I made (roughy) 3/8'' cut stars and primed them with 85/15 Meal/Mg/Al (not sure on the mesh size, I think it was about 40-60)
However these take fire very easily and I suspect that prime was overkill.
This is a very good Green IMO and seems comparable to Emerald green which I've also made.
EDIT. here's a movie of a mine made with these green stars, but unfortunately they look white and washed out, they look much better in person.

I'm messing around with some greens as well, but I am at somewhat of a purchasing freeze (except for essentials). So, I'm trying to develop an organic green based on Barium Carbonate and Ammonium Perchlorate, since they are materials I already have. My initial experiments showed that a good green may be very possible. When I have something that is useable I'll report back (hopefully next weekend)!

The smoke from all these might still be pretty bad, though, as the barium and strontium will be changed from it's safe salt to some potentially toxic species. Still, I like the concept very much. Thanks for the formula.

Indeed they do, it's used as an X-ray contrasting agent for the digestive tract as it's not absorbed into the blood stream.
Don't they have patients drink barium sulfate slurries for diagnostic imaging?

Sometime I'll have to compare it with a Barium carbonate green, if I do I'll be sure to get a video.

The last batch i made I ran out of the acetone alcohol mix i was using and grabbed the water spray bottle to finish. absolutly ruined the green color came out a yellowish green with the accent on yellow not a real pretty color. but it was differant anyway.
