Green star??

[PC]

Looking for a non-toxic green star formula, I found this on Skylighter:

Green
Potassium nitrate 15
Sulfur 2
Airfloat charcoal 1
Copper powder 4
Red gum 1
Dextrin 1


Doesn't look like it would be green to me. Has anyone tried it??

I haven't, but without a chlorine donor, it's not going to be VERY green.
Copper tends to burn 'greenish' without one, but not very.

Here is one for fun and mindless and subs as rocket fuel, credit to Dave Stoddard.

Barium Nitrate 55
magnalium 26
Parlon 16
P,Perchlorate 3 you can use it without the perch or regulate burn speed with it a little but for rocket fuel that perch in this formula gives the rocket a strobe / machine gun effect burn time 9 seconds a inch so if your wondering how much over the tip of the spindle just under .5 inch i press mine just like i would BP rocket fuel,for red same formula just use Strontium Nitrate,even though its a better oxidizer minus 5=50 parts just a fun no fail simple formula,i guess for a binder for stars use a dash of starpol and be done with it.

I've been tempted to but haven't. For non-toxic greens I've used barium sulfate, perchlorate, magnalium, and organochlorine; and the Yates green based on zinc & a KClO4. The perc seems to shift the color from the greenish blue of nitrate-oxidized Zn comps to a bluish green. My only experience with copper powder comps has been with chlorate or perchlorate and an organochlorine to make blue. I've also tried bronze key filings in gerbs, with inconsistent color production among the sparks.

How do you figure that barium compounds in the smoke are "non-toxic"?

In fact, pyro smoke _at_altitude_ is seldom a health-and-welfare issue.
But toxicity is toxicity.

I don't know of any _effective_ green that's non-toxic.

Who said anything about the smoke? I meant in the making of the stars.

And, you're saying that ingesting barium carbonate would not constitute a
"toxic encounter"?

FWIW, Ba carbonate is quickly decomposed by stomach acid (HCl), resulting
in barium chloride (which is highly-toxic in terms of heavy-metals
accumulation), and carbon dioxide, which is only 'toxic' (in the
'social' sense) to those around you when you fart.

There's not a _problem_ with compounding such a mixture, so long as you
understand the hygiene rules and remember that the smoke is just as toxic
to those who breathe it as the composition is to those who ingest it.

But to irresponsibly tell folks that it's "non-toxic" is completely
inexcusable. Part of our art involves protecting both other
practicioners and our viewers. It seems you're not interested in either.

No, it's just that I think most people here when they write of toxicity are concerned with risks to the fabricator. Although there are some who like to smell the smoke! Since the risks of the smoke are the same regardless of which Ba compo is used, I think it's clear what people are asking about when they refer to non-toxic greens, since the BaSO4 compos have been written of that way.

It's like when people are concerned about the toxicity of a pesticide. It's not that they don't want it to kill rats, insects, whatever. It's all context.
