The reason that moisture usually condenses on a mirror is because the air
in the room is warm and humid, the cold mirror cools the air right next to it,
and some of the water condenses out of the cooled air. If the mirror is warm,
then even the air that's right next to it stays warm, and there's no condensation
on the mirror.
