This has been a very fun project and have enjoyed learning a lot about different types of ovens and different techniques people use to make them. I am not looking to make the worlds greatest oven, I just wanted to make an oven that I can enjoy for years in the spring and summer. To insulate my oven I used 2" ceramic blanket and another 1" of a perlite/cement mix then stucco. I also used 2" perlite/cement mix and about 1/2" of sand under the firebrick(I know I could of done that different, and use more insulation, but thats life). I still have to finish the oven with stucco and couple of different little things. I will let you know how it turns out and how the pizza taste.
The Good: The whole experience, and the feeling of buildling your own oven
The Bad: Cutting some corners, Trying to fix the problems, should of use more insulation
The Ugly: My Hands after working with all of the mortar, brick, concrete... they hurt,
