HI and Thanks David.
My local refractory supplier opens tomorow after their extended Christmas break. I hope to be able to get some there.
I have the rest of the materials sorted and poured the top for my oven thisafternoon. Things are finally going.

The oven has no cracks and performs beautifully.
I recommend this build for anyone looking to build a low cost simple oven. Many fires and pizza have been built in it with no signs of failure.

Not sure why so many people are doubting its construction.

Feel free to build what you like. I was just trying to share a design that worked for me.

The goal was shoestring budget. I met the goal.

it's become a tradition to cook pizzas for new years.
here's a quick video of the pizzas and ovens from the 2013/2014 party...
Oven still performing great and showing no signs of failure.

happy new years and hope the year is full of good pie.

People doubt because they are conditioned to think "refractory" is needed.
I've been looking at my company's refractory knowledge base. Alumino silicate refractories that are extremely robust at temperatures over 1830F, are not so robust at pizza oven temps unless first fired over 1830.
i.e high temp refractories are not necessarily so good at low temps. They need the high temps to cure.
The info discusses "low cement" bricks, which have some calcium aluminate cement in them, plus other binders that harden by different mechanisms, to allow for when the CAC passes through a weak zone from about 660 degrees up. Yep, CAC hardens by hydration, and although better than Portland, can still potentially breakdown at pizza oven temps.
Homebrew. arguably, has cement that hardens by hydration, lime that hardens by drying and carbonation, and clay that hardens by drying.
So in fact it is a pretty good "low temp" refractory.
You built it, it works and it has lasted.
I for one, feel more confident about the mortar in my oven just because you have taken the risk and demonstrated the durability.
Thank you very much for increasing the knowledge.
