Off Grid Posted March 17 Share Posted March 17 If the density is correct then my guess would be impure barite. If you have access to a really hot flame, like a brazing torch, stick a corner of your rock into it. If you get a pale green flame it's barite. If your density is high then maybe magnesite (3-3.2). 1 Link to comment Share on other sites More sharing options...
