A dark crust certainly will absorb energy from the Sun during the fall. But
that radiative energy gain is going to be a lot smaller than the convective
loss from a stream of -40? air blowing across the stone at 100 m/s or so!

I'd think a smooth fusion crust would actually provide better heat transfer
than a rougher surface.
