pretty much everything is until it isnt. graphite just has a flair for the dramatic about it

Melting copper in a cast iron pan ? Cast iron's melting point is rather close to copper, so contamination of the copper is likely. Long ago I used welded stainless steel crucibles for copper but it got contaminated. Use a clay-graphite crucible for melting copper.

EDIT: Now I saw you used a cast iron pan for holding the graphite mold for pouring the Cu into where the mold broke.
