Bread-Bakers v105.n015.5

FWIW, I put about 3 cups of hot water in a shallow pan when I turn on the 
oven and steam gradually starts being generated as the oven warms up.  By 
the time the oven is up to temperature, steam is coming out of the oven 
vent built into the right rear stove burner.  After the bread has been in 
about 10 minutes I remove the pan, which typically has about 1/2 cup of 
water remaining, and stop the steam production.
