Making black powder - PyroCreations

There are two methods to make BP: The ball mill method and the precipitation (or 'CIA') method. You'll need a ball mill in any case. While both methods work, they each have their own advantages and disadvantages. The main disadvantage of the ball mill method is that it is essential that you have a safe place to let your mill do it's work. You need a place with no
