the volumes he is quoting are ridiculous! 500g+ of flash is massively dangerous and a maximum of 40g is strongly advised.
NEVER screen flash IT WILL almost definitely eventually cause an accident.
don't store large amounts of flash.
squeezy bottles are not suitable for dispensing flash. Also these types of bottles are usually clip top so can cause friction of the contents trapped in the lid.
MADNESS!

Dude, your f**king nuts doing that!
The first explosion is 1 pound (roughly 500g), i dont see much left of that thick wooden wardrobe thingy. I imagine there would be even less if there was a human in front of it.

ANYONE READING THIS, DO NOT FOLLOW IT! ITS HIGHLY DANGEROUS, IF YOU HAVE TO MIX FLASH MAKE THE SMALLEST AMMOUNTS 5g WILL MAKE A LOUD REPORT AND EASILY HURT YOU!!!
The fact your screening it is one thing but screening it mixed with Sulphur is insane, lets hope you dont get a Darwin award for this!

Isn't that 125% You should always make your formula's add up to 100 and have +x for anything else like binders.I've been making fireworks for years and my favorite mix for flash powder is ..75% potassium perchlorate, 25 % sulfur, and 25% dark pyro aluminum.

The Consumer product safety council in the US is kind of aggressive and made them shut down and stop distributing all things in regards to and related to Flash.
They send letters to just about anybody who orders perchlorate and dark aluminum about how likely they are to kill themselves even if there isn't direct evidence that somebody is trying to make flash.

I am trying to perfect the technique by producing copper colloids: I add fine zinc powder to a solution of copper sulphate. Zinc is higher up the reactivity series than copper, so it displaces copper from a solution of copper sulphate to give metallic copper. The zinc goes into solution, as zinc sulphate. This method often produces growths of dendritic (fern-like) copper, but a copper colloidal suspension of very small particle size can be achieved by adjusting the concentration of the copper sulphate and the pH. This might be a good method for producing copper powder of very fine particle size. I do'nt expect a nobel prize for this, though.
If solution chemistry does not work for aluminium, I will consider the high-temperature route, involving electrolysis and molten salts. I'll keep you posted on my progress......

Perhaps this should not be in the Flash thread...
