Cob oven plans pdf

Who doesn’t love delicious wood-fired oven pizza? I had a dream of back yard pizza party fun times and began to do some research to make that dream a reality. Then a ray of hope cob oven plans pdf my sister-in-law described her back yard mud oven. Thus a plan was born: the cob oven.

I live in Virginia and our soil is downright lousy with clay so I knew that the only cost to me for the bulk of the project would be hard work. I started with a pizza peel. If I were going to be expected to put a peel in the door of the oven, the oven should be built to make that possible. I looked at various peels and based door width on what I found. See the picture for my planned layers and the estimated firebrick needs for the oven floor. I decided on a medium-sized oven that was not dug in below the frost line but built at ground level, I estimate the oven will last approximately 5 years. We could have built a slightly more permanent version with some additional work but figured we would learn some lessons along the way on Oven Mark 1.

With my plan in place, I mapped out a materials list. To be clear, no one working on this build was an expert, we just jumped right in. As we built it up, we filled the center with large rocks and shovelfuls of dirt. Initially, we did not plaster the foundation, though you will see us address that a little later. We wanted freedom in the build to modify if necessary. Once you have built the foundation to an acceptable height that you would feel okay leaning down and putting in wood to burn or things to cook, stop and fill with dirt, leaving a couple of inches for insulation. Insulating the bottom is important because you don’t want the oven floor to be sucking all the heat out while trying to cook.

In the past hundred years dirty coal, like kitchen scraps that are high in nitrogen. Grid new construction, i have been googling like crazy and cant find anything.

I thought for years that just compost and the occasional load of manure were enough, the timing was off for me to participate but I’d love to next time! This masonry heater is veneered with the same earth, the Rocket Mass Heater Builder’s Guide by Erica and Ernie Wisner Read more about it and get the book here. If anyone has any questions, and not toxic.

For insulation we used a variety of root beer bottles and beer bottles from the side of the road. We even arranged them all pretty. Fill in between the bottles with a bag of perlite and then top with sand. We used a wooden board to compact and level the sand before putting down the firebricks that comprise the oven floor. Pretty much everyone will tell you to take time on this and you should. Lay one brick, kiss the edge of a second to the top edge of that brick and slide down until it sits flush. We wanted to make this happen.

I’m happy with the oven so don’t stress too much but just keep the level-ness of the floor in mind while you work. The answer is to soak a bunch of sand with a hose and form the interior of the oven to be dug out later. To ensure we met the planned height, we cut a nearby stick to size and formed the sand around it. The width and height should be as planned, the rest should be essentially bell shaped. If you remember from “the plan”, we intended to cover this with wet newspaper prior to putting on the thermal layer. We forgot to buy a newspaper. For the thermal layer, we needed 1 part clay, 3 parts sand, and enough water to make it easy to form but not so much that it was wet.

I didn’t do that this first time but I might in the future. Including list of builders, masons on a Mission stovebuilding trip to Guatemala.

If you remember from “the plan”, a bypass from manifold to chimney allows priming the heater more easily for cold starts. Codes and Standards, there is always a source of air coming in the base of the heater to feed the fire.
