OK, I have my results.

It is a BAD idea to melt copper in a steel box. It does eat the
steel. The steel box is ruined. I was kind of lucky that copper did
not spill. Also, an electric furnace takes too long to melt it.

In addition, the cast iron pot was cold, not clean enough and the
bottom of the casting is porous as a result.
