"Ball milling media for pocket change. Here's a tip for all those pyro types that mill their own black powder. Much has been discussed about using a non-sparking media, and whether or not ceramic balls will cause an explosion, possible health problems from lead media, etc.



I've been using good ole U.S. of A currency discs for that purpose for the last five years with nary a problem. The nickel and quarter denominations work very well. They don't spark; They are about impossible to wear out, and they're cheap. I use 12 quarters and 20 nickels to mill 100 grams of lift in about 3 hours. The coins cascade in landslide fashion down the inside the tumbler and provide a shearing/rolling action to the mix.



I mill the charcoal and potassium nitrate for 2 hours and add the sulfur for the last hour. After pressing, corning, and screening, my lift BP is as good as any commercial product I've tried. My milling tumbler is an ancient '70s model Thumblers Tumbler with a rubber jar of about 3 pounds capacity. It is soooo-- old I had to replace the jar and sealing ring last month, the motor let go about 1986 and I replaced it with a continuous duty rated fan motor which continues to grind on and on.





And here’s yet another variation on charcoal sparks from Flint Hapirat for all ye tropical pyromaniacs. Thankee, Flint."

I was wondering if this would work? or should I just use brass?

would it be possible to ball the Kno3, sugar and wax together or is it too dangerous?
