Hi pyros,
I was thinking there Is a composition named slow photoflash which consist of:
-potassium perchlorate 18
-barium nitrate. 10
-magnesium fine. 36
-shellac. 36
What do you think about this composition? There Is a composition with magnesium and magnalium with only 14%of oxydizer which makes a big flash.. i would like photoflash as long as possible...Someone have tryed this composition??
Really slow photoflash

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

Slow photo or illuminating flashes are often under oxidised and rely on the little oxidiser present spreading the mix which can then burn in the air.

As you can, or SHOULD see, perchlorate is not used, but chlorate.
No, I have not tried it. I have no application for it.

In my series of experiments which I would best entitle as "What else can magnesium reduce?", a lot of the ones, when overfuelled produced an absurdly bright and long lasting fireball due to vapourised Mg burning in air. 1:1 plaster of paris:Mg powder comes to mind(however it produces quite orange illumination). 1:1 SrCO3:Mg produced a red one as expected, however didnt have that much power, adding 10% perchlorate helped it along.
Basically have a sulfate/carbonate/other slowish oxidiser and magnesium in a fuel rich ratio and voila.

Search this and see how many flash formulae there are, and how many are now regarded as unduly dangerous
