Enwere ike iji eriri igwe agbaze ọla kọpa n’ime ọkụ na-agbaze induction?

You can choose graphite crucible for melting copper in ọkụ na-agbaze ọkụ, or you can buy induction furnace ramming material yourself, and directly ram the furnace wall lining on the furnace wall to directly smelt copper. It is definitely not possible to use an iron crucible.
