Make German Dark Aluminum Powder in Bulk
I'm trying to do this and it's not working. I actually have the same rock tumbler as you. I'm using Walgreens brand aluminum foil I used a paper shredder to cut up my foil. I'm using 25 1/2" steel balls and i used a tbsp of charcoal. After an hour the aluminum is just flatten that's it, it's not turning into grain. If you could tell me what I'm doing wrong or anyone it be much appreciated. also when you put in the next big hand full of the aluminum do you but another tbsp of charcoal in? thank you for the help
