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?


Steel turns blue when heated.

NH4SCN is ammonium thiocyanate.

A simpler test is to dissolve a little in hydrochloric acid, dry the
solution over heat (acid fumes!), and see if it turns blue. You could
neutralize the acid by adding garden lime or baking soda until it
stops fizzing. I don't know if other metals would interfere.

That sounds like a plan. The induction furnace is 100 kva by the way
