I don't own a heavy enamel pot, which seems to be the best for no-knead bread. Is it possible to make good no-knead bread in a glass casserole dish?
i STRONGLY recommend against it. i can speak from experience that the sudden change in temperature can cause glass baking dishes (particularly when they go from as high of a heat required by no-knead bread to a cool room temp) to shatter and explode! i had a pyrex dish go supernova on me once, sending hot flying glass shards all over the kitchen. how i didn't get hit i'll never know, but it melted holes in our floor and left scorch marks!

you can pick up some heavy pots suitable for no-knead break baking at thrift stores and garage sales for a song. if you can find a cast-iron dutch oven, even better! i urge you to dig around a bit. the results are really worth it.
