Stainless wood fire oven build
« on: February 15, 2020, 06:02:12 AM »
Hi all!  :chef:

I was recently on the hunt for a stainless steel pizza oven in the 3-4 pizza size range, and i found one at the online retailers that looked interesting, but the Italian manufacturer had the worst customer service i have ever encountered, so i decided to build one myself instead of supporting that company.

The cooking/fire area will be about 70x96 cm, and im thinking about insulating it with a couple of layers of ceramic wool. I have room for about 10-15cm of insulation in the dome, and i will add about 5cm of wool on the bottom.

Im not sure what kind of bricks to use, im afraid regular fire bricks will be too conductive, but i cant seem to find any other stones in the stores that will do better.

What i am looking for here is guidance mainly on the insulation and stone issues. I am already pretty far along in the build as far as the the shape of the oven goes, but if you have suggestions on improvements anywhere, just shoot at me! I am a rookie on wood fire ovens!

I use Whitacre Greer firebrick on the front half of my oven.  They still conduct faster than the Italian saputo clay but I think they are on the lower end of what you can get in USA. 

Nice looking build so far!

Thank you! What kind of oven do you use?

Do the regular fire bricks really burn the pizzas that bad? Im not sure what temperature i will be able to get my oven to, but from what i have seen on youtube, people seem to struggle to get/keep the stainless steel wood ovens above 400c. It would be interesting to get some input from someone who runs a steel wood oven.

It all depends on what firebricks you use and what temperature you have them at when you bake.  Since my firebricks are at the front they don't get as hot and work well for my purposes which is to finish off the bottom of the pizza.  I've not tried them in the back.

For your build, the amount of insulation you have will play a big factor in maintaining your heat.  I use very dry wood and split down to about 1.5" size to keep a very large fire going all the time.  I can stay between 800-950F while cooking about 25 pizzas per hour in a Pizza Party oven.

Craig - is Duratec 750  or 1000 available at any retail locations?  Are you using it in your oven?

That was from another member who put it on top of his firebrick deck that was too conductive:

Thank you for this, i was litterally a few clicks away from ordering a bunch of cheap fire bricks, i didnt think it would be that big of a differance. Today i finally found a company that sells saputo stones for wood fire ovens, and i ordered two 50x50cm stones that i will try, and if i am happy with the result i will buy two more.

The total cost so far has been like 350 euros, and the only thing remaining that i have to buy i think is the insulation in between the domes and more saputos. I also bought two 2,5cm thick Calcium Silicate plates that i will place beneath the saputos for some insulaion on the bottom, if that still isnt enough i will weld a second bottom plate and put some insulation between the plates.

I have room for about 10-15cm of insulation in the domes, would it be better to buy ceramic wool and stack them up, or is that overkill? Is one layer of 10cm rock wool enough?
