The man shook his head. "That's not the problem, lad. See, we can get the stuff out with the other impurities, but we want to isolate it. If magic makes it heavier, that's something worth checking out. We want to get the base material, see what properties it holds. Thing is, it's bloody hard to do. Most of our purification methods need magic, and melting it is a no-go. It seems to burn off the properties we're trying to keep. We need a better solution."
