I was house sitting for a friend last month and I didn't have my Dutch Oven available for Bread Baking.
I was able to use a couple of their Pyrex Baking Dishes instead of a Pizza Stone.
Just preheated the dishes in the oven like you would a pizza stone.
preheat a broiler pan with them to add a cup of water for when the dough goes in.
It turned out about the same as the Pizza Stone Method.
all in all the Dutch Oven Method works best but these tweaks work well in a pinch.
