successively layers of overlapping foil being applied
Here's a photo of an oven I worked on this past weekend. The baker does not want a cover over the oven, and this presents a real problem in protecting it from the elements. An unprotected mud oven in the northeast might disintegrate rather quickly so we decided to wrap the mud dome with aluminum foil. Any water that got to the foil would theoretically just drain down the side. Perhaps over the insulation we'll wrap the oven with another layer of foil become applying the stucco. There are some who say an oven needs to "breath," but after a mud oven has been fired to 1,000 degrees F., the dome becomes rock hard and the ability to breath seems to be a moot point.There will definitely be an update on this oven.

Hi,
Did you have any problems with the clay's "breathability"? I have just finished a clay dome and am debating insulating it with vermiculite/clay or vermiculite/cement. I think the cement mixture would be more protective of the dome if breathability is not a problem. any suggestions? Thanks!

I don't think breathability is a problem. After all, there is a huge opening in the front of the oven. I'd leave out the foil and go with a 6 parts perlite to 1 part Portland cement insulative layer. Make it 4" to 6" thick. That's my opinion.

OK I'll do that! Thanks!
