I am going through some old lapitary stuff I bought a gem show several years ago. One of the small baxes is marked Bronsite 1 1/2 Lbs. on top and BronZite in green pen on the side both hand written. Inside is a bage with some fine brown powder. I have been looking on the net and have not found out what this powder is for. I assumne that it is a polishing medium of some kind. Can some one help out.
Thank you
