Here go some reds by me and Rip, makers of www.ruspyro.net. Central flame area is white, because of infrared ray emmision of heated gasses, аnd any digital camera is senitive to them causing central area overbright. All mixures tested by me are 10g mixture samples placed on paper. Enjoy and comment :)

Anyone wants me to post yellow and mixed color fires (e.g violet or aqua) ?

HELL YES! Post whatever new comps you have

I also would be interested.

 

I don't think boric acid will inhibit the reaction between Mg and KNO3, as it is intended originally to inhibit the reaction of Al and KNO3. I would treat Mg with K2Cr2O7 before mixing in comps that are bound with water, if the Mg is very small particles. When using larger shavings it doesn't seem to be totally nessisary.

It will inhibit the reaction in the same way, if you know the chemical process leading to instability of metall+nitrate mixtres, you will clearly understand why boric acid works the same in both cases.

 

Just remember - pyrotechnics is not just remembering quotes from the books, it is a chemistry in first place, don't forget that. If you want to be good pyro you must be a good chemist to, to understand why and how combustion and other chemical and physiacal processes go.

Engager, the problem with boric acid in contact with magnesium is that it is corrosive by itself! The nitrate/metal reaction may be inhibited but you will end up with a mixture that is unstable when in contact with moisture anyway!

 

I also wonder how stable the strontium perchlorate/shellac composition is since strontium perchlorate usually is too hygroscopic for pyrotechnics? I don't mean that it will spontaneously ignite but can you really store it without absorbing moisture?

Any one tried the "Russian Red #1" as a star or as a flare?

 

I made it and tried igniting it as a powder, it don't burn in continuity and extinguish him self every time I light it.

 

If any one got experience with this....I will be glad to get some advice
