Found a few lbs of it in an induction furnace that I bought in auction...
These are oxidized metal grains. The oxidation color is bluish and
most closely resembles blueberries, though I am somewhat color blind.
It is NOT magnetic and looks dull grey if I grind off the oxidation.
Any idea what this metal is? Could it be cobalt?
