I've used Baechle system 7 stars primed exactly like this but with a super-prime, they take fire well and stay lit. Only tried them in whistle-boosted shells and over-lifted mines, so not sure how they'd hold up to a flash break or similar...

Thank you Mortartube for the information. I will try that out when I can get hold of some titanium. My attempt seems to be a very bright gold with bright sprinkles of silver, very beautiful but not how I want it.

Hi.I tried this composition for red stars but it i dont like it.It is very faint red i think and i want to make another.
KClO4 70
SrCO3 15
Red Gum 9
Dextrin 4
Charcoal 2

I added 25% alcohol solution and i pumped them....

So firstly i want to ask if compositions with magnalium are better.
And if veline system is good for stars and if it only needs alcohol for them to be pumped.I want to make Red and Green for now...

Thanks.

Who is the author of this composition. It looks as though it was intended for use with KCLO3 not KCLO4 as there is no chlorine donor in it. Try adding 10% - 15% of parlon to your composition and it it will be transformed.

Yep the velines are generally pretty good in colour saturation except for the blue. (hint 70/30 magnalium helps with the colours). Yes you can bind them with pure alcohol.

It's from lancaster. There is a very similar one with chlorate replacing perchlorate. You get what you get with organic reds and greens. They generally have poor color saturation. With organic formulas, you may not even need that much chlorine donor. Part of the chlorine goes to prevent the formation of MgO and Al2O3.

Nuke, if you have the chems, you may want to try KCN's Red, it's a metal (Mg/Al) fueled star and it's a very bright red with nice colour saturation, they light quite easy also (I've atached unprimed stars on shells as a rising comet and they lit with no problems)

Red:
MgAl - 10
Parlon - 8
PVC - 5
Airfloat charcoal - 3
Red gum - 4
KCLO4 - 45
Sr(NO3)2 - 25

If you're looking for an organic red, Shimizu #1 Organic seems pretty good (So i'm told, never tried it though)

Looks like an interesting comp there PGF, any reason for 2 Cl donors ?

Anyway, I'm after a tried pink star formula, good saturation, easy ignition, metalic or organic fueled, doesn't matter ? I want to go from C6 to pink

No idea actually, the guy who invented it says it performs better with both PVC and Parlon than just one or the other. I tried only the original formula with two Cl donors, and it works very well so I don't intend to experiment as chlorine donors are scarce and expensive

Asking for pink is very vague. Do you mean a more orange pink, a "lady's color" type pink which is slightly purple-ish (hot pink I guess), or just a whitish red?

You can always add potassium nitrate to a strontium based star composition and a bit of a calcium compound and that will certianly offset the depth of the red (or, for the hot pink, a copper compound instead of calcium).

Thank you very much.I will add parlon and i if i dont like it i will make the one you have put on

I'm glad you like them mate

This is what the reds look like, they're in a 2" can with some C6.

I want to go for the "lady's color" pink The first color comp I tried was Lancasters KP#1 red, which IMO is a whitish red/pink-ish? Good for a "starter" color but I'm after a "lady's pink" pref metalic fueled, nice and bright.

I'm assuming you've already looked at the PFP?

Your best bet obviously at this point is to have a slightly bluish red mixture with a lower strontium content than normal star compositions and a magnalium/chlorine donor fuel base. I can't say I've ever seen a perfect "hot pink" colour anywhere. Usually when I think pink, I work with CaSO4 and SrNO3.

It might be handy to experiment with 10g samples of various compositions and see which (Such as 5/1/1/1/2, or 6/1/1/1/1, etc) yield you the best colour before fine tuning it to yield the best results and dedicating your components.

[pyromaniac303]

Magenta would be a good one, its listed in one of the Veline colour combinations, but I haven't tried it myself.

[knackers]

hey guys, could somebody tell me the best way to form this star, ( i thought with this much metal it may be to difficult to roll ) but at the moment my options are roll or cut,

Red Ti star,

Sr(n03)2.............40
Ti.......................20 ..sponge
MgAl...................15..60#-->150
Pvc.....................15
Red gum...............5
Kclo4.....................5

i tried this on my test plate and it was very glittery and not as red as i was expecting, so i added 10 (Src03) and it did red up quite abit more so i'll give it another 10
