I am in the process of making some black powder. It is in the tumbler right now and as I understand, once it is good and mixed, ground, you should wet it with water and alcohol and make it into a paste, then dry it and shift it. Well it is kinda cold and wet here right now. So I started thinking about the best way to dry it out. I thought, if I leave it outside, it may freeze. Then I started wondering what effect freezing may have on it. Then I started thinking about my freezer and how it seemed to draw the moisture out of things I left in there for quite some time, and wondered if I could dry it out that way. That got me wondering about freeze drying. So... Has anyone ever tried freeze drying black powder? From my research, it looks like freeze drying leaves micoscopic pours in whatever has been freeze dried. Seems like that may even help the powder to burn better/ faster. Has any other mad scientist tried this out there, or tried freezing away the moisture in the freezer? From what I have read, most people say that putting it in the freezer would attract moisture rather than dispelling it. Still, not all freezers are created equal. Your thoughts?
