Making Black Powder with a Ball Mill

We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.
