How to Build a Cob Oven - Part Two

Part Two shows how to mix & install the cob thermal mass layer (no straw) and the insulating layer (lots of straw). Note that our soil was about 50% clay and 50% sand content. We want about 25% total clay, so we added an additional 2 parts sand for each 2 parts soil. Since the soil is already 50-50 sand-to-clay, the total is 1 part clay to 3 parts sand, or 25%. The thermal mass layer has no straw. This is the layer that gets hot and holds the heat from your fire. The second layer has tons of straw...basically as much as you can mix in. Straw is a good insulator, so the second layer helps hold in your heat.

For more information on cob ovens, I recommend Kiko Denzer's book "Build Your Own Earth Oven"...it's a complete "how to" including how-to sketches, list of tools, inspiring photos, and much more.

Sorry to keep you waiting! Someone else is editing the videos for me, and I upload them as soon as they are complete. Hopefully part 3 will be ready soon, and then we'll be adding other natural building tips. Thanks! Sigi

Can this be done by one person?

[sigikoko]

@scsteeldrums yes! Absolutely! It's not as fun as doing it with a group, but absolutely doable as a one person project. Good luck!
