[QUOTE="zubenelgenubi, post: 4210847, member: 63706"] That was one of my thoughts as well. Could not get it to light, actually got it red hot with no ignition. It is also much harder than coal, which is around a 2 - 3 on the mohs scale, whereas this is a 6-7. I narrowed it down to a pyroxene or amphibole group mineral, which some are almost indistinguishable from one another. I settled on amphibole due to the cleavage angles. [/QUOTE]
