i do have a large crucible furnace that takes a silicon carbide crucible
for melting brass. however, since i am doing this without any help and
that i am living on painkillers ( one every 6 hrs ) for the trashed left
side of my body. the coffee can foundries are more than enough. i am
here 24x7x365 days a year.

the last time i checked:
copper 1083 deg C 1981 deg F
steel 1370 - 1505 deg C 2500 - 2735 deg F
the steel ultimately depends on the type of steel.
