which stars with only these chemicals?

[superspike23]

I lost all my chemicals due to a water leak.
I just got a little money and I bought:

 

kno3 1kg

Aluminium Powder 350# Flake 200g

Aluminium Powder 350# Atomised 200g

sulfur 200g

Vine Charcoal 500g

Isopropyl Alcohol - Isopropanol 99.9% 1 litre

Bentonite Clay 500g

Dextrin 500g

Ferrotitanium 500g

 

waiting to buy more, how nice formula I can do?

 

thank you.

[ivars21]

C6, C8, TT, Willow, (combination with FeTi/Flake Al will give you nice tail), White stars, buy some baking soda from grocery shop and you can make D1/N1 (would be hopeful having boric acid) that's pretty much I can think of

[shouldnoteatindat]

there is also hardt charcoal streamer #4 that is very nice, and you can add 5% al to make it even better. And afew Kno3 whites you could make but they arn't that good.

[pyroman2498]

Almost any charcoal streamer ,D1, yankie flashers, sulfur white , TT with 10% F/T added, to flasher is a great looking star if you can pump a cavity star or roll them

[LambentPyro]

Bleser Blonde Streamer is an excellent choice. Something simlar would be Yishiki Kamuro (believe I spelled that right) that call for a high FeTi percentage, so it's a bit expensive, but you won't regret the results it produces.

 

Hope this helps.

 

Best

[Mumbles]

I think you mean Nishiki Kamuro.

[superspike23]

thank you for your answers.

I watched videos of blond Bleser streamer.
it's pretty.
Do you have the formula?

[Mumbles]

Sure do. I'd bet that google, or the search function here have it as well.

[superspike23]

Sure do. I'd bet that google, or the search function here have it as well.

ok thank you

 

you were already saying that we should not trust google for formulas

You can always just buy the book if you want to be positive.

I say or do something wrong?

[superspike23]

I found this formula:

 

kno3 45g

c 29g

fe ti 15g

Sulfur 6g

dextrin 5g

[skid68]

I found this formula:

 

kno3 45g

c 29g

fe ti 15g

Sulfur 6g

dextrin 5g

 

That's the one. I'm a big fan of Hardts Brocade as well.

KNO3 - 29

Pine C - 34

Sulfur - 6

FeTi (mixed) - 25

Dextrin - 6

[LambentPyro]

I think you mean Nishiki Kamuro.

 

Yes thank you

I found the boric acid.

which is composition who use it??

[Mumbles]

Boric acid prevents a reaction between nitrates and aluminum. It's a common additive for glitters. Usually, a percent or two are added dry to a composition, or a solution of boric acid is used to wet the comp. I prefer to use a solution personally. It doesn't add anything to the effect, just prevents any deleterious reactions from happening and the composition from being degraded or becoming dangerous.

 

It is commonly added to glitters and silver streamers containing both nitrates and aluminum. The additional presence of flake aluminums, or stronger bases (oxalate, carbonate, bicarbonate, etc) can make a reaction more likely. I generally only use it when one of these additional factors is involved, but a lot of people use it in everything.

 

One warning. Boric acid is incompatible with magnesium and magnalium. Don't add it to any compositions containing these things if you want them to function as intended.

[superspike23]

thank you very much.

I can use either of the boric acid or sodium bicarbonate for d1 composition?

[Mumbles]

I don't think you understand. Boric acid does not and should not replace sodium bicarbonate. D1 contains sodium bicarbonate, and will not function the same without it.

 

Potassium Nitrate - 53
Sulfur - 18
Charcoal airfloat - 11
Aluminum atomized, 325mesh - 7
Sodium Bicarbonate - 7
Dextrin - 4

 

As I mentioned before, I only really use boric acid when the composition contains potassium nitrate and a flake aluminum, or potassium nitrate, any aluminum, and another ingredient that is a strong base. In this case, I probably would use boric acid (either dry or a solution) for this composition since it contains potassium nitrate, aluminum, and sodium bicarbonate (a base). If you don't use boric acid, you can identify the unwanted reaction by the composition heating up, smelling of H2S, or smelling of ammonia.

[Shadowcat1969]

No, you use the sodium bicarbonate as specified in the D1 composition, THEN add the 1% of dry boric acid, then wet and process your composition.

 

OR use a boric acid/water solution to wet and bind the composition.

[superspike23]

Ok I understand.
It is an additive but never replaces another product.

[superspike23]

I found this formula:

 

kno3 45g

c 29g

fe ti 15g

Sulfur 6g

dextrin 5g

Should I add a layer of prime for this composition?

[Mumbles]

I prime everything just to be safe. It's better to use some excess BP or green meal than to have the stars hitting the ground unlit.

[superspike23]

thank you

[superspike23]

I tried tonight a 2 inch shell.
With stars "Bleser Blonde Streamer"

shell weighs 37.3 gr

I used 4 gr of lift, composed of 70 kno3 /18 vine C / S 12 and granulated.
For the break, I used coated rice hulls and 0.5gr Fp (KClO4 50/50 MG)

there was too much wind.

 

There was not enough to lift and break

[superspike23]

I made a new test.
With the same composition.
I used 8 grams of lift powder.
1.5 grams of flash powder.
I put 4 layers of gummed tape.

and I used a time fuse 2.5 cm.

The result is better but still not perfect

What do you think about it?
