A while ago, I was experimenting with KCLO4 / Benzoate black match formulas, but misplaced my notes with the formula that worked really well.

I recall it containing mostly KCLO4, and a lesser combination of Charcoal and a Benzoate. I searched here, FW.com, and couple different books - but can't seem to find it.

Does anyone know off hand or have a functional formula?

Thanks

There are several alternative benzoate-oxidizer mixtures mentioned here, but in the context of whistle formulae for pyrotechnics.

I finally found my notes, thanks. I really like the stronger burning match for crossettes, AP go-getters, etc. It burns rather fiercely, and makes lightning fast, almost explosive (with one or two strands only) quick match.

KCLO4 - 70
K Benz - 26
AFC (Willow) - 1
Sulfur - 1
Binder - 2

Mix via wet process (Oxidizer added to other ingredients after well mixed, and wet to paste for coating string)

It was nothing more than Whistle slowed down with AFC and Binder, with Sulfur added to lower ignition temp (is my non-expert opinion).

Not sure how I found it originally, or why I tried it, but I use it as a 'Thermalite' replacement (though I've admittedly only seen video of thermalite burn, never in person)

I dunno what “thermalite” is..but that formula’s gonna be hotter than a.. well, I’ll skip the off color joke here :D


I like smoke! On food or in the air equally well.
