Bruce, interesting stuff. I now have my own small oven. I plan on changing how I make the carbon bread foam. The last design has the carbon bread foam removed. The lower oxidation cylinder is removed and a larger hole for a larger diameter cylinder has been cut. This will allow for more insulation. This first bottom pail will be built with ceramic blanket, original plan. A second bottom pail will be assemble for carbon bread foam. This way the bread testing will not delay the new ACFC much.
