These are oxidized metal grains. The oxidation color is bluish and
most closely resembles blueberries, though I am somewhat color blind.

Any idea what this metal is? Could it be cobalt?



?? Oxidized copper looks a lot like that too ... have you tried smashing
one of those chunks with a hammer ?


Definitely not copper, when ground down they look dull grey. Not magnetic.
