Got these firebricks, how should I build a pizza oven with them?

Here is Tscar's build link.

Ts is a master oven operator, builder and works in the masonry industry. Look him up and study. You can build up side walls with square brick and set the arch on top of the side walls to get more height. You can also stair step (corbel) the side walls a bit to gain clearance and then cut the top brick with a skew angle to accept the curved arch brick. All this could gain you 5" of width or more depending on how elaborate you want to be. The arch brick are not very thick, so the oven will heat quickly and then cool quickly compared to other heavier ovens. Great for piazza, challenging for bread. I think you have about half the brick needed, maybe less to complete this oven, and a little planning could result in a really unique build.

If you use full 5 curve segments will it increase the width? 23" wide is on the small side as you move the coals/fire to one side for cooking. 15" in height is not too high. The key is good floor and dome insulation for a good preforming oven. Refer to Tscarborough's build, it was a very nice barrel build. https://community.fornobravo.com/mem...8-tscarborough

Thanks for the reply!

The width won´t change much, I´ll get slightly more than a half circle, so maybe somewhat smaller ...

My plan was to push the fire inwards, but maybe it´s better to aim for a square design rather than rectangular?

I could´nt find Tscarboroughs build, maybe it´s my search skills, maybe i´ts the forum ..

Fizz,

Welcome to the forum! That is an interesting shape for fire brick. A barrel vault seems to be the best choice. From the stamp in the pic I would have guessed that they were an ultrahigh 65% alumina. However, I did a quick search of those markings and found Höganäs Bjuf Refractories. A click on their products, link to a page shows a BJUF.SX (line 4) as a 35% alumina alkali resistant firebrick. So, I'm guessing that the "36.27" stamp is the actual alumina content (much easier to cut with a wet saw than 65%). From reading their page they have been in the business for a long time. You may be able to contact them with some questions. Aside from all that, clean and dry them real good so that the mortar will stick, and have fun .

Thanks for the reply! (and the behind the scenes work I suppose one of you moderators did to delete my double posts )

The dome will be about 12-13 inches high, and the base will be about 23 x 35 inches, what do you experienced builders think about that?
I´ve been reading some threads here, and it seams that 12 inches is a pretty low dome, if I use 5 full curved stones I´ll get a little over 15 inches height, is that better?
I´ll use the oven mostly for pizza, so a low oven will heat up faster, which is better I guess?

The bricks were pretty easy to cut, at least compared to the concrete/granite I´m used to working with ...

Hello everybody!

I got these bricks from a friend who´s had them stacked outside for problably a decade or more.. They look pretty worn and torn, but feel solid ..

There are 63 curved ones, 26 medium sized ones (somewhat larger then a regular brick) and 10 larger ones (the whiter ones in the first pic). I also got 12 lighter ones, that I think are isulating firebricks..

I layed them out on the garage floor, and created the footprint (second pic), and decided to go with a barrel design with 4 and a half curved brick to create the roof ...

Any input would be highly appreciated!
