I would think that the glaze at cone 05 would be vitrified and therefore
wouldn't be a problem. My concern would be if the clay is still porous at
that cone, then absorbed moisture could freeze and crack the tile. You
could test the hypothesis by thoroughly soaking a glazed tile, drying it
off & putting it in the freezer.
