Je, chombo cha chuma kinaweza kutumika kuyeyusha shaba katika tanuru ya kuyeyusha induction?

You can choose graphite crucible for melting copper in induction melting tanuru, 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.
