Milling Black Powder posted in Pyrotechnics: Just wanted to get a poll on varying options of most efficient yet safest way to mill black powder without a ball mill. I used to use a coffee grinder however the last time I milled some I resorted to a mortar and pestle instead, which was far too much work. I know ball milling is the most common for large quantities.
