Using Pyrex casserole dish as bread cloche?
I've done it several times with good results. It shapes a round loaf so that it rises up instead of spreading out, and you can see when it has risen enough to bake, but it would be easier to remove the finished bread if it were a real cloche with a knob on top instead of a bowl. I put a lot of oil on the bottom and sides of the bowl so that the bread does slide right out, but still it can be a little tricky getting it out. 

The 1.75 qt bowl has the right depth to width for me, but I wish they had a bigger bowl with the same proportions.
