Let me know, still think it's a piece of smelter slag.... We call it pour off, it's the scum atop the good stuff.. Sometimes you pour some of the good stuff along with it...
Poured onto the ground he cooling pattern fits, center hot spot with edge cooling first. Crystal pattern from center cooling last.
Flat side is ground side.

Don't take the first bid
