Hi all

I haven`t got any BaCO3 or Ba(ClO3)2, but is there a nice (probably metallic) composition
with BaNO3? I`ve tried emerald green from pyroguide, but I think the color is quite washed out and not
very green...

Greets

just do search in pyrotechnic composition you will get a post named russian fire by mumbles.
Or you can try out this
Ba(NO3)2....4parts
dark aluminium(fine).....1part
pvc....1/4 parts
sulfer...1parts
boric acid...1 to 2 percent
bind with dextrin and water.

Try the "brilliant green rubber stars" This is the only green comp. I have ever used, I have tried a few but didn't get very good color with barium nitrate until I tried this one and decided I didn't need to test any more mixes. This is a great barium nitrate based green, the only drawback is that you must "screen slice" or cut the stars, I'm a big fan of the screen sliced method.

Here's the link to the project http://www.skylighte...rs.asp#continue

all you do is replace strontium nitrate with barium nitrate(as he says at the end) and i would also suggest trying his citron yellow variation of the composition, very interesting

Some reason's to try this comp.:
1-great color
2-stars are very bright
3-I've never been able to blow one blind, the mix burns very vigorously
4-the stars dry in around 3 hours because of the use of only solvents
5-stars are rock hard
6-stars are parlon (chlorinated rubber) based making them water resistant

you could also try:
Radiant Green Firework Star-cut with straight acetone, or roll<br style="font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; ">40% Potassium perchlorate30%Barium carbonate15%Dark pyro aluminum (or any -400 mesh or smaller flake aluminum)15%Parlon or saran
(+5%) Dextrin, only if you desire to roll them, use 25% alc./water


I posted the rubber green formula to the formula database along with a few others and for some reason they never got posted, anyone have any ideas why?
Not really sure yet what i should write for a signature so I am writing this.

Radiant green is better made with magnalium. If you make it with Al, you will get a short white tail from it. If your Emerald doesn't look deep green, you must not be doing it right. I've been told that the Klumac red/greens are a bit better than ruby/emerald colors, with less chemicals.
Some people think I'm sane, but they're crazy too.

This one is pretty good. I use it with strontium nitrate for red, but it's a good green too:

Barium nitrate 37
Potassium /per/chlorate 30
Mg <63Ám 14
Parlon 14
Red gum 5

Or with magnalium and +5% dextrin.

I think I will try the brilliant rubber stars from Skylighters... They semm pretty simple with a great color...
@ Alexpyro how did you prime the stars? On Skylighters are two
primes indicated, which one is better?

I found emerald green to be a very nice green. Also they are easier to light compared to nitrate-only stars.
Maybe they are not properly dried, that might cause them to look washed out.

Another green I would choose is Hards Green Star #5. A strong hotprime is recommended.

As far as I understood, this is a to step system. The perchlorate prime is hotter, but needs to be primed itself to ignite under any circumstance. Thus a layer of the BP based prime is applied on top of it. And to be really sure you can dust them with a thin final layer of normal BP.

In my opinion the best brightest and most brilliant green star is:
55 BaNO3
28 Magnesium
17 PVC/Parlon

though one of the more expensive ones. This composiotion should be pressed.
It can be pumped or rolled if you add 5-7Parts Redgum as Binder and use plain Ethanol/Acetone as solvent.
They dry very quickly, but rolling stars with Redgum as a binder takes pretty long.

buell green, prob the best green i have seen. its super bright and not much MgAl used like in the rubber stars, so its not very expensive and BaCO3 is cheap. buell red is great too.


Green Metallic
PotassiumPerchlorate--------------------------------35.35
Barium Carbonate-------------------------------------25.25
Magnalium, granular, -200---------------------------14.14

I`ve tested buell red, I think its really nice.
But since I haven`t got BaCO3 buell green comes out of question.
And it`s just 5% more MgAl then in the rubber green, I think I`ll bear that...

Yes, that one if marvellous, if one cannot get hold of barium chlorate and/or prefer brightness before depth.

You can also bind it with parlon. Use 10% and the rest PVC.

Maybe not as bright as compositions with Mg, but very usable:

KClO4 18
Ba(NO3)2 45
Red gum 10
Parlon 9
MgAl 63 mic. 14
Dextrin 4

@ potassiumchlorate, Yep, the real deal Posted Image I have tried other greens that gave deeper/brighter green colors, but this one is a combination of what i like. Easy comp, easy rolling, easy ignition, no smelly ugly dangerous sh*t like NC, just a fun and fairly safe comp to work with! And the final star in the air? Just great for little expense. I always say in my posts ''there is no easy quicky'' in pyro, but this one proves me wrong! Posted Image

question to potassium chlorate-as you told about coarse pvc in the post russian green fire I have doubt about burning of this mixture with coarse pvc...will it burn?

I don't know. It depends on how coarse it is. Mine goes through a 125Ám sieve but is still a bit "coarse". I think coarser than that would be too coarse.

okay i will try this formula with my pvc.

Yea I can confirm it... you really need good reactive metal fuel to get good green, otherwise you'd need barium chlorate.

Magalium, dark pyro, and magnesium is the best for good metallic greens. If the flame isn't hot enough it will look candy apple or washed out...

I can report that Emerald Green is a great comp, but the crucial ingredient is really a reactive metal fuel like magalium, dark pyro, or magnesium... they all call for it. I tried it with spherical Al and it does not work.

I finally ended up with formula Verde 2 from spitfire...

The second star was TT to green.
My camera doesnt`t pick up colors very good, but it`s a nice green
in person.
I`ll test out a few shells with this formula in 2 weeks, when they turn out good I`ll post a video...
