55 Cancri e is a hot planet with a molten rock and metal surface, with compressed solid rock beneath that. We were just wanting confirmation on the conductivity (convectivity rather) and composition of its atmosphere.
NASA delivers, from two of the Webb's instruments. Dayside is 1810 K, which must be convecting from some (violent) wind; carrying said wind, is carbon monoxide and dioxide.
CO is a reducing-agent. If there was any iron-oxide to smelt, on this surface, it would be quite smelted. I suspect it just sinks. Rising up rather, they say: are these carbon gasses themselves; there's no way a planet this hot keeps its gas unless it is being replenished. It's not a stiff dead Black Planet, however much it acts like one on the surface.
