Roeland's catenary shaped brick oven.

Peterrrabit, are you in?
Listen to The People, mate. These folk know which way is up: these blokes have been there an done that, while I was still eyeing off a nipple.
So my ant heap is SO well insulated beneath, plus a fair show on top.
At 50mm of each, I'd suggest you may just get by.
Eyes closed: ears open. tru.

Last weekend I decided to "test drive" the oven by making a pizza.
I covered the oven with 2 layers of Superwool blanket and applied some
aluminum foil on the temporary chimney setup...
At the time the pizza went in the top dome sensor (between brick and Superwool) read 300C.
The bottom sensor (under the floor tile) showed 200C.
Although the pizza was good and very tasty, it was not golden brown...
Next time I will try higher temps..
Pics attached..

How long did it take to cook?

You can cook pizza at that temp, it's about the temp of a conventional oven.

You'll probably be happier with another 100 degrees though.

It took 4 minutes, which is not too bad.
I would like to try the 90 seconds in a 485C oven though..

I started finishing the outside of the oven.
I cast the stainless steel chimney in refractory concrete, but I think that
was a mistake.
To increase the drying process, I heated it to 80degr C using a halogen lamp.
Unfortunately it already started to crack
I expect it to crack even further when I fire it up.
So I consider that part lost...
Will have to think of a different way to construct the chimney.
Perhaps I will make an all SS sheet construction.

I constructed a mold out of wood and aluminum sheet to make
the outer shell of the oven and that works out really nice.
The shells that come out have a real nice smooth finishing.
Pics show the mold and the first 2 shells placed on top of the oven.
I am using 2 layers of Superwool ceramic blanket and since I had some
extra space left I decided to add a sheet of fiberglass insulation.

A brief update on the progress:

I finally finished the 6th (and last) shell to cover the dome.
I'm very happy with resulting catenary shape of the dome.
Started also some tiling on the front for the landing.
Next oven (..) will have a bigger landing area, would be more practical...

This gets my vote for one of the better fire shots


any chance of getting a higher resolution for wall paper?

[Peterrr]

Here they are, resolution 1500x1000, should be OK for wall paper.

Is it me and the wife or is anyone seeing faces in these fires??

One of the Pizza-party guests would not leave.
We could not find a better way to get rid of him...
