My Cast Refractory Oven Build

You are looking good!

Here's my perfect world scenario:

1.5 - 2"/40-50mm for the home
2.375"/60mm for catering
2.75"/70mm for a restaurant

and so it begins...
92lbs of portland cement, 4cuft of perlite....
the rain finally let up again so it is time to get back to work.

Hmmm so my logic was good... I was just out on the thickness!

thanks James!

ok, another 2" of perlcrete above the first 2" layer of perlcrete. and NOW i can install my bricks! well, after a couple of days.

By the way, it took exactly one 92lb bag of portland cement and 4cuft of perlite to make a 4'X4'X2" slab...in case any one needs to know.

We've finally fired the first oven at pizza temps. Works bloody well and cooks pizzas in under 2 mins.

We have cast them all but we still have nine to put together and fire.

What kind of insulation do you have under your floor and on your dome?

Hi Joey, we've used 3" of vermiculite/cement underneath and on top we have two layers of ceramic blanket and 2" of vermiculite/cement. In top it gets only luke warm to the touch but quite hot underneath. The next ovens will have 2" of Cal-Sil board and 2" of vermiculite/cement underneath.

I was thinking of going with 2" of perlcrete on the dome and then another 2" of stucco and just skipping the blankets, has anyone gone this route?
