Homemade flash powder

The ingredients are KNO3/Al/S. The ratio is 5/3/2. It burns slow. Is it because the KNO3 is not fine powdered? I don't have a ball mill or any grinder just a mortar and pestle. And the Aluminium is 400mesh. Comment please.

thanks for that but the potassium perc. is too much expensive. i can get 2Kg of KNO3 for just 3.5 $. if i get the pot. perc. i will try the screening method.

Yeah the same thing happened to me, so I bought Mg and MgAl to make fast burning flash.

uhmmm,all that did was fizz. where's the flash? get rid of the pot.nitrate and use perc. or chlorate then screen it thru a 40mesh 2x then thru a 60mesh 1x stainless or brass wire cloth screen...when you get all the chem's...you can use almost any heavy wall paper tube any length you want. try mixing 65/25/10 perc./al/s (or) 65/30/5 Dont ball mill it or grind it,just screen it. you'll need to think of away to cap the ends.
