Anyone knows a gold or yellow star composition using Sodium Oxalate and KNO3?

Is there any nice slower buring Golden or Yellow star composition using Sodium Oxalate and KNO3?

 

I know the Gold glitter formula, but I dont want a tail. I just want a golden or yellow star without any tail.

1) KNO3 - 72%, Na2C2O4 - 5%, S - 23%.

2) KNO3 - 70%, Na2C2O4 - 7%, S - 20%, C - 3%.

3) KNO3 - 63%, Na2C2O4 - 15%, S - 14%, C - 8%.

 

These are very old compositions.

That a nice color indeed. I don't have Sodium Nitrate though.

Do you have mangalium or magnesium? Or even, I guess, aluminum. My bet would be on fine magnalium as an ideal fuel - the finer the better. Start with 7:3 ratios of oxidizer to fuel, like making slightly over-oxidized nitrate flash, then add in sodium oxalate and binder incrementally to achieve the desired burn speed and color.

Yes, I have Magnalium. Will try to make a yellow/gold comp as you suggested this evening.

By the way - no composition is too fond of water as a binder when it comes to burn rate, especially a metal one. I recommend using acetone and a gum / soft polymer of some type to bind the stars.

 

Let me know how this all works for you.

 

Cheers.

I stick to water or alcohol as the solvent. I roll my stars and Aceton makes to much mess. On top of that, its a quiet toxic compound, and the weather doesn't allow me to be outside
