Oven Possibilities

I still continue to be amazed by the wood-fired ovens people build. There really is no right or wrong way to do it. No matter how you put it together, the odds are very much in your favor that your oven will work. Certainly you'll learn from the experience, and if you build a second oven, the chances are that it will be different from your first oven.

What I find most interesting about the video is that the oven is totally uninsulated, and probably the builder had reasons for not insulating, but I can't think of any. My feeling is that no matter what type of oven you choose to build, an insulated oven will mean less firewood you'll have to burn and better bread.
