Hello everyone

I'm trying to find the formula for the mentioned flare or for very very bright flares.

I found some threads on the forums but nothing specific

Hopefully someone can help

#2bright white from spanish paper is extremly bright.

If you really really want bright figure out how to use 70/30 for that.

Any chance you could specify the chemicals/recipe

The brightest flares are made with sodium nitrate and magnesium. A lot of excess magnesium can be used (50-60 %) and stability is usually ok if the magnesium is treated with linseed oil first. DIfficult in humid areas though!

Just to follow up on this. He entered the discord chat a few days ago and we discussed this. As CrazySwede suggested, we provided a sodium nitrate based flare comp. The following is from Hardt.

 

Hardt white flare #1:

Magnesium 30-50 mesh: 58
Sodium nitrate 37.5
Binder 4.5

 

He uses a Polyvinyl alcohol-acetate resin. Anything non-aqueous should work well though to hopefully prevent degradation. Phenolic, red gum, PVB, etc should all be pretty decent binders.

Try this for insanely bright:

 

KCLO4 70

MgAl 41

CuCO3 5

 

Despite the heat produced, the CuCO3 still seems to add a slight blue'ish tinge to the flame that makes it seem extra bright.

(and yes, I know it doesn't quite add up to 100, but it does work)
