I have stored a quantity of black powder, composed for: 75 potassium nitrate-15 charcoal-10 sulfur. (Make ball mill, 3 hours)

And the possibility exists of that, during his(its) manufacture, it mix (75-15-10) can be contaminated
with some particles of powder of POTASSIUM PERCHLORATE.


My question is: In normal conditions of storage and temperature, can be exists dangerous risk of fire ? explosion in the mixture 75-15-10, for containing this small contamination with some particles of POTASSIUM PERCHLORATE?

What says the chemical "Pyro" STOICHIOMETRY (estequiometr?a) in this matter?

I have to destroy these kilos, immediately or it(she) is necessary "a precise quantity" of the product contaminant, in order that it can react with all black powder ?

SINCERELY GREETINGS from Madrid (SPAIN) !!!

I am by no means gurranteeing your safty (lawyers should be kept behind the line marked on the floor) with this post, but personally i wouldn't worry about a very small contamination, there are sensitivity issues with mixing perchlorate with sulphur but when the ratios are this bad (or good depending on your point of view) ther isn't going to be a problem.
