Do you think that is worth to contine with this composition?

 

(sorry for my bad Ang.)

 

(edit: it's really more orange then red, so i've changed the topic)

More orange than red if i'm honest. Drop the lithium and NaHCO3, sodium will ruin any other colour other than yellow. You should get better results then.

I will try, but i don't have anymore KClO3.

I know you can make orange out of CaCO3 but this compo was made by mistake, i screwed up by mixing in sodium bicarbonate.

Aluminium(better titanium) ………………………………4

(4mm star, the sparks are not very visible on the video, it's has much more sparks in real life)

That still looks pretty orange. I'd suggest a real chlorine donor. I've said this elsewhere, A true bright color I don't feel is very possible without secondary chlorine donor. Chlorates or perchlorates are rarely enough.

 

Are you sure your chlorate is pure enough? You've mentioned this before that you make your own KClO3. If all the sodium contamination is not removed, it could cause this orange color.

You won't belive it, but it's a p.a. Pottasium chlorate(99%). I become it from my chemistry teacher in school.

Add parlon, it will bring out the red more nicely, and read the thing givat linked to. If needed add boric acid at about 1%, this is keep it more stable, but keep it as low as possible because it will colour it green.

Hellow after a long time.

 

Yeah I impruved my red composition.

 

Name of composition: Matawzh’s sparkling deep red II

Composition Type: colored star

Creator: I am:)

Color/Effect: nice deep red with silver tail

The Composition: (by weight)

Strontium nitrate...................................71

Potassium chlorate................................33

Powdered shellac...................................9

Aluminium(atomized 400mesh) ...............7

PVC......................................................9

Boric acid............................................+1

 

Any Precautions/Incompatabilities: quite dangerous composition. It's necessarily to add 1% of boric acid, because it make compo more stabile.

Precedure/Preparation:

Bind with hot ethanol, then stars are PUMPED (10mm or less, stars burn for quite long time)

I couldn't get out any more red.

Not to bad looking however you should probably get a slightly better video. The smoke isn't doing you any justice...

[Salute]

Oh, I am really sorry about the video. I'll test stars with stargun and you'll get a better video.

 

Sorry again, cheers.
