Slow Sulfurless Black Powder? Answered
I have tried to make some sulfurless black powder by grinding 3 parts sodium nitrate (a potassium nitrate substitute, using this method to make it from ammonium nitrate) and 1 part charcoal (I tested it and it didn't burn good so I added more charcoal (probably making it a 2 KN03:1 C ratio)). It burns extremely slow (if i laid a pile of the bp that was 1/8 inch wide and 1 inch long it would probably take 5 or more seconds to burn all the way). I got the charcoal from a burned out bonfire (I don't know what type of wood it was but it wasn't willow or pine), I collected the black chunks that aren't all the way burned out. I am wondering what the problem is, is it the charcoal or the sodium nitrate? The sodium nitrate is in its purest form, thats what it said here.
