Chemistry / Re: What is the correct recipe for flash powder?
« on: 22/01/2015 23:00:21 »
From my testing, I have noticed the excess of Sulfur really accelerates the reaction, but I would say this is more of an explosive than a flash powder at this point although I am not sure where you draw that line, and my magnesium is fine, 99.99.
But if experiments contradicts common knowledge, one must take the opposite position of common knowledge, earth isn't round anymore, no disrespect intended, but over 500 tests with same comp with over 5 different types of Mg, S and KNO3 with all different suppliers.
I am not saying it's the best most safe thing every, of course not, but I am saying, from my experience which I would say is fairly decent with this particular blend, what I am doing is quite safe to handle, and while I would't stake my life on it, nor would I with anything as energetic as this.
Interesting, where did you find it? If you don't want to post it, please feel free to send an mail.
Who the hell made that? I would't come within 10 yards of that mix.^^
I did some minimal testing on normal gunpowder with magnesium added in, works really fine, cheap too if you find a nice provider, only 'expensive' part is the Magnesium but I have finally found a really nice supplier which are about 1/7th of the price of the same quantity from Sweden: But I haven't tested making stars out of it, not sure how it would burn, unsure how Mg does with alcohol for rolling and I am not very familiar with the ways of stars to be honest, I have only done simple strontium/gunpowder stars and they worked but, I am not an expert any sense of the word.
Wow, this is unlike anything I have ever seen with flash, it seems like a big.. fraud..
How can it not ignite in open air, sounds as if it is just pressure sensitive? I would like to see some hit tests on it, but if it isn't a hoax: It seems awesome, and you are just going to get me back into flash powders again :p

Once upon a time I reasoned like that - trusted in my own test results rather than common knowledge

I browsed though a database of 300 pyrotechnic compositions.

There must be cheaper ways to make a nice white star with much longer shelf life.
