I'm late to the parade, but having fun making no-knead bread. I've done two loaves at a time using my two enameled cast iron dutch ovens (7 qt and 5 qt), and tried to figure out if I could find a 3rd vessel that would work. My eyes landed on my big crockpot which has a removable stoneware "crock" with a pyrex lid. Would this withstand a 450 deg. oven? I'm not sure I can actually fit three vessels in my oven, but if they work it would be nice to make three loaves at once to give away or freeze.
