Cool. We cant use our oven that hot or it sets off the interconnected smoke alarms and sends the dogs scurrying for the dog door. Not so bad in the summer, except for the panic one dog has, but in winter at 20F it's not too good for whippets to be out there that long.
Another trick we use for the crust is a pie pan of water in the oven with the bread. Doesn't come out quite as nice as yours 32_20fan, but it works OK.
