Building my Cob Oven Base

I have been working on the base of my Cob Pizza Oven for a few weeks now. I had to work on it slowly so I didn't injure myself. I also had the kids help me .

I started by salvaging some old blocks we had around the house.

Then we filled it with busted bricks and rock we had.

I mixed up a batch of cob and made an insulating bed with cob and beer bottles.

After  encasing the bottles in cob I poured leveling sand on top to prepare for the firebricks.

  

 

 I placed the firebrickes and laid out where the cooking surface would be. My dome will be 27 inches in diameter and 20 inches tall.
