Jvanderh has it right.
For about five years, I've been baking bread with a no-knead, or nearly NK method.
The bread is baked in a covered vessel at 500 degrees for 30 minutes, then uncovered at 450 for another 5-8 minutes.
When the loaf is formed and has rested in the baking vessel, I put it in a cold oven, set the temperature to 500 and the time for 42 minutes, because it takes my oven 12 minutes to heat up to 500. This method works perfectly.
BTW, the formed loaf rests on a piece of parchment, which becomes a sling for easy handling of wet dough. The parchment stays under the bread in the baking vessel.
