:) Bright green stars (my favorite)

 

I don't remember when I started to use this Green Stars composition's formula & also unknown about its creator, but just now this is my favorite green stars.

 

Colour/effect::- Bright green

 

Composition in weight:

 

Barium Nitrate 12

Parlon 3

Mg/Al (200 mesh) 3

Dextrin 2

 

 

Cut or pump stars, damp composition in 75/25 W/A.

Use BP-Silicon prime or Veline's superprime.

 

(Don't use PVC instead of Parlon)

I was wondering if it might be possible to replace barium nitrate for strontium nitrate to obtain a red color?

Most of the time, yes. I would have to look at my notebook but I think this would be close to a 1:1 substitution.

A little lighter on the Sr side. 5:4 or 10:9 is probably better

Strontium nitrate atomic mass is 212 and one molecule of it has 6 oxygen atoms in it ( Sr(NO3)2 )

Barium nitrate atomic mass is 261 and one molecule of it also has 6 oxygen stoms in it ( Br(NO3)2 )

so 212 grams of strontium nitrate gives same amount of oxygen as 261 grams of barium nitrate

212 Sr / 261 Ba ~ 4 Sr / 5 Ba or 0,81226... / 1

ive got some Mg/Al. i might buy some chems and try my first colored stars using this formula.

 

EDIT: I calculated using information above, how the comp using strontium nitrate would look like.

 

Strontium nitrate 9,7 (originaly 12 Barium nitrate)

 

Parlon 3

 

Mg/Al 3

 

dextrin 2

Barium Nitrate 12

Parlon 3
Mg/Al (200 mesh) 3
Dextrin 2

Will this work with Mg/Al (150 mesh)?

Thank you! :)

Finally, some useful color that does not require (per)chlorate.

That's a nice composition, I use the same formula but with 5% more MgAl and Red Gum as binder.
It is a bit less bright than Mg/Nitrate Green but has a much clearer and deeper color, it is my favorite for non Ba(ClO3)2 Green stars :)

I know right!

I was searching forever for a decent green without it.

Its also pretty cheap :)

Original So that would be?
60 Barium nitrate 60 Barium nitrate
Parlon 15 Parlon 15

Mg/Al 15 Mg/Al 20?

Dextrin 10 red gum 10?

When you write mg/al intend to 50% of magnesium and 50% aluminum or simply Magnalium?...

 

Thanks.

Thanks.

If mg/al is used in a formula it means magnalium. Different metals are listed as separate components.

I asked that question myself not long ago!

As I thought, thanks for the clarification.

In the coming days it will come to me all you need to do the colored compositions and can not wait to experience.

So i need to put a slash in there?

Here is the barium carbonate magnalium stars using parlon and red gum

And here is the red using strontium carbonate both are identical ratios except one is .2 barium carbonate for green and red uses .2 of strontium carbonate. Parlon and red gum in both. Don't mind the kids at the end they love this stuff as much as I do lol.

can I replace the parlon with pvc?

What is effect when PVC is used instead of parlon...
Posted

The parlon is the binder as well as chlorine donor so I don't think PVC will work as well. May end up too sticky though it might be worth a try with less solvent. Don't remember the comparison between the two as chlorine donors so if PVC gives up ore it would be a good swap if it will bind as well.
