The rock would shatter a porcelain tile and remain whole. Persons that stumble upon the rock often ask 'is that titanium?'
There was no sulfuric odor or any particular one that I noticed.
Color, composition appear consistent throughout. With a proper machine it took the edge off a 5.5-6 mach reinforced steel drill bit and did not bother the rock. The grounds could not produce a smear.
Fine grounds from the rock ought to be used to polish a window.
I thought the same, that it's some mineral composition and not a elemental metal.
I'll do a specific g test.
I appreciate all the input. My apologies for providing such limited info in the beginning. My thought was simply to throw the pics on the forum and catch some ideas but there are great insights here that I am grateful for.
