1. A cold crucible comprising:
a cage called cold cage comprising sectors made of an electrical conductor material, and within which a charge to be melted is to be introduced, and
a cooling device with a heat-transfer fluid, the cooling device being configured so as to cool down, from inside, each sector of the cold cage,
wherein at least one of the sectors of the cold cage comprises a functionalising housing and the at least one of the sectors is removable, the functionalising housing being configured to accommodate therein at least one functionalising device of the cold cage, and
wherein the at least one functionalising device is based on a material that is less a good electrical conductor than the material on which the sectors are based.
