Metalic Substance from PoF

What drops the Metalic substance used in the smithed armor for Plane of fire?

I'd hate to waste my time farming the first field if it doesn't drop there.

I've seen it drop off the magma golems, but I also haven't seen a lot drop.

[gathrintain]

just the guys on the bridge, or any of them from the second field.

Bridge and 2nd field, pretty much any of the giant lava golem types, it's insanely rare I've seen like 2 in 4? months or so.
