Not conclusive if it helps, but I'm in the habit of rubbing my container on a carpeted floor while swirling. We have one room in the house with carpet still....I will generally set my little toaster oven to preheat at 425, once there I turn it down to 400 and place the tray of bullets in, watching every 45 seconds or so until I see them turn liquid, then set the timer for 20 minutes. And def keep your powder container sealed and in a controlled environment.
