I built this oven soon after I became enamored of building with cob [clay dirt lots of sand and straw. Kiko Denzer's book was a great help. And cob is a pure delight to work with. If there is a sculptural cell in your body cob will bring it out.....for better or worse. I'll add other shots later. It seems pretty clunky to have to upload pics one at a time. This is in a lot of ways my favorite stage of the oven's completion but it needs lime plaster on it to protect it from the elements better.
