Well, this weekend was a bit of work!
Saturday I formed the sand dome, which acts as a form for the actual oven. Used about 500 lbs. of sand! The floor of the oven is an elliptical shape – 32″ wide x 36″ deep. The height is 17″. After shaping the dome, I covered it up with junk mail flyers – soaked in water.
The following day, I built up the oven itself, making a lot of baseball sized balls of sand, clay and water. The mixture wasn’t too wet – just enough to keep the sand and clay together.
I did manage to get the form covered over completely – with a brief interruption by mother nature and some much needed rainfall. In a couple days, I’ll lay out the oven door, and cut it out. Then the moment of truth when I get to remove the sand form! I’m planning on making the opening around 11 1/2″ tall, and 16 – 18″ wide. Once the opening is made, I’ll build a door, and then add 3-4″ of straw and clay insulation to the exterior of the oven.
