I found this site today and must say it is excellent. I have followed the newsgroup forums (alt. bread recipes and rec.food sourdough) for a number of years, but I note that they are now little used. Is it because of the flamers and spammers?
Question: Why do we bake free form loaves (sourdough and baguettes, for example) in a very hot oven (425 degrees or more) compared to pan loaves which are baked at 350?
I don't think it is necessarily because of the shape of the bread--though free form loaves do benefit from starting out on a hot hearth.
I think the hotter and cooler baking temperatures are more based on the other ingredients in the bread. French/sourdough bread is "lean" which means it's just flour, water, salt (and yeast or sourdough culture). Breads (such as sandwich breads) with other additions, such as sweetners and milks etc. will have additional carmelization due to the added sugars from these ingredients in the dough. These are baked a lower temperatures so that the interior is fully baked before the exterior becomes too brown or burns.
Lean doughs can handle very high temperatures better because they don't have these additional ingredients , and I think a very hot hearth and oven also assist in creating those beautiful streaming bubbles in the crumb that we all love to get!
But i've been baking all my pan loaves at 400 to 450 degrees, too. It seemed to work for me.

But in general, lean doughs are baked at higher temperatures, and enriched doughs are usually baked at lower temperatures.
Thank You breadnerd for the hints. For the last couple of months, i've just been playing with my bread. Someday i'll have to look at a recipe, again. This makes good since too.
Now there's something else to play with besides sourdough and flour, oven temps. I'm almost done with the twenty five pounds of bread flour i got for Christmas, i'll have to get another. We make a loaf every day, but they'll be smaller now, maybe. Plus my wife thinks i should make something else besides white bread. So i add some WW, or rye from time to time. It makes her happy, but white bread is more fun.
We learn something new, every day around here.
