Monolithic dome vs pre-cast facetted dome.

Re: Monolithic dome vs pre-cast facetted dome.

Use a refractory castable in the 1400c range, and include approx. 5% by weight s/s needles for strength.

I am so glad I found this forum! Opinions needed.
Which material do you think is best for a mobile pizza oven?
Ferrocement with addition of fire clay or Refractory Concrete.
Thanks for all the imput.

Hi Mark/Carol, I've put a fair bit of information on this site about making a castable dome. If you're interested please go to :

We have so far built nine ovens and have five ovens going strong using this method.

Cheers

Thanks everyone for the replies and information. I will probably go with a monolithic dome cast in place. Once the weather breaks and dsries out a little I hope to get a start excavating the base etc.

Re: Monolithic dome vs pre-cast facetted dome.

I have seen a steel barrel cut in half length wise and used as the inside of the dome then insulated. Will the thickness of the steel be thick enough to hold up to that kind of heat?
Any help is welcome.

Hi Carol, is this the sort of thing you're thinking of?

Using the cut down barrel is not a smart move, after a few firings it will have flakey rusty crud falling ono the pizzas.

Hey Mr G,
Sorry it's taken me so long to reply. I was thinking of something other than Willeys project but I really like what he has come up with. My plan is to hand form my one piece oven over a sand form and I would also like to build a oven like Willey's. I have enjoyed your photo's and appreciate how easy your instructions are to follow.
Thanks for all the advice.

Re: Monolithic dome vs pre-cast facetted dome.

I went to one of the events they were at on Mercer Island Wa .
The floor is refractory bricks .
I think the walls and dome are the same , to achive a 4 in thick surface .
Then insulation blanket , wire mesh and more concrete to get the smooth surface.
What interested me was how well the dome was insulated , they stacked about 10 pizza boxes on top of the oven.
