Molten cryolite rather; I think the metal pooled in the bottom of a pot could be drained off or even allowed to solidify (it would still be conductive.) A related problem is that the walls of the pot cannot be allowed to get too hot. If this were not the case, they could simply insulate the pots to reduce heat losses to some arbitrarily low level. |
