Arc melted button.
I've been experimenting very a very crude arc melting furnace made from a box of firebrick, an old 275A stick welder, two graphite electrodes, and a small graphite crucible. I melted this button of solid nickel down out of a small pile of the nickel balls described above. Not bad for a $15 furnace (not counting the welder).
