pyrowinner Posted November 5, 2012 Posted November 5, 2012 (edited) 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 12Parlon 3Mg/Al (200 mesh) 3Dextrin 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) Edited November 5, 2012 by pyrowinner 2
VickeA Posted November 16, 2012 Posted November 16, 2012 I was wondering if it might be possible to replace barium nitrate for strontium nitrate to obtain a red color?
dagabu Posted November 16, 2012 Posted November 16, 2012 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. -dag
AirCowPeacock Posted November 17, 2012 Posted November 17, 2012 A little lighter on the Sr side. 5:4 or 10:9 is probably better
Oinikis Posted January 8, 2013 Posted January 8, 2013 (edited) 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 nitrate212 Sr / 261 Ba ~ 4 Sr / 5 Ba or 0,81226... / 1ive 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 Edited January 8, 2013 by Oinikis 2
Stef727 Posted February 13, 2015 Posted February 13, 2015 (edited) Barium Nitrate 12Parlon 3Mg/Al (200 mesh) 3Dextrin 2 Will this work with Mg/Al (150 mesh)? Edited February 13, 2015 by Stef727
Ubehage Posted February 14, 2015 Posted February 14, 2015 Thank you! Finally, some useful color that does not require (per)chlorate. 1
Titanium Posted February 14, 2015 Posted February 14, 2015 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
Stef727 Posted February 15, 2015 Posted February 15, 2015 (edited) Thank you! Finally, some useful color that does not require (per)chlorate. I know right! I was searching forever for a decent green without it. Its also pretty cheap 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 Original So that would be? 60 Barium nitrate 60 Barium nitrateParlon 15 Parlon 15Mg/Al 15 Mg/Al 20?Dextrin 10 red gum 10?

Nitrotitanite Posted January 20, 2017 Posted January 20, 2017 (edited) When you write mg/al intend to 50% of magnesium and 50% aluminum or simply Magnalium?... Thanks. Edited January 20, 2017 by Nitrotitanite
OldMarine Posted January 20, 2017 Posted January 20, 2017 When you write mg/al intend to 50% of magnesium and 50% aluminum or simply Magnalium?...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!
Nitrotitanite Posted January 20, 2017 Posted January 20, 2017 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.
MudDuckPyro79 Posted March 18, 2017 Posted March 18, 2017 (edited) Here is the barium carbonate magnalium stars using parlon and red gum Edited March 18, 2017 by MudDuckPyro79
MudDuckPyro79 Posted March 18, 2017 Posted March 18, 2017 (edited) 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. Edited March 18, 2017 by MudDuckPyro79
bengalPyro2000 Posted March 30, 2018 Posted March 30, 2018 What is effect when PVC is used instead of parlon...
OldMarine Posted March 30, 2018 Posted March 30, 2018 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.
