I wondered about that. Hopefully I'll get myself in gear to get that roof 
built before the snow flies.

I had planned to put the chimney out through the roof; do you think that 
would be a problem? I'd buffer it with cob, build the chimney a little 
higher to clear the roof, and then make a green roof. BTW, my husband stuck 
his hand over the chimney when the fire was going full blast, and he said 
it wasn't really that hot! Amazing how the oven must be sucking up the heat.

Ah, so I'm actually following a tradition! We let the heat equalize for 
half an hour before baking, but friends with an oven suggest more like an 
hour or two. Guess I'll experiment with that.
