My Brick Selection ok?

[john_aero]

Ok managed to get time start the build again.

just have pour the slab for oven and then build.

I have the following bircks already and want see if they will suit?

i got the red bricks for 50 euor and tapered furnace bricks for free.

i have 120 red brick and 55 fire bricks.

the fire bricks are left overes from a furnace re lining job in my last job and are very heavy bricks. just want see if they are ok to use

the red bricks came from old fire place and are the old handmade tyre brick. the only issue i have is the have a hollow section.

I plan use arched bricks for my tunnel donw, the red bricks for 3 block high side wall before the arch and on their face for the floor.

Re: My Brick Selection ok?

Those "free" bricks will work fine in many part of your build with the exception of the hearth floor (due to the taper direction), they may be super duty, similar to what I used in my build. If they are super duty (high alumina content) they are a little tough on saw blades. Can't comment of the others though.

Maybe contact AMAC on the WFO forum, he is from Ireland and just finished his build last year. Maybe he can give you better info on what is available in your neck of the woods.

All of the ovens on the site you linked have serious design issues. I would rethink them as a viable option.

Re: My Brick Selection ok?

They don't have insulation under the hearth and little if any on the dome. The firebrick will take a long time to heat up, conversely they will hold that heat for a long time. The frogged brick should work OK, but the frog is going to be an issue. How do you plan on cutting them to use?

Re: My Brick Selection ok?

Cutting i have large and small geunders with diamond blades and also have lian consaw

Issue is i have enough tapered brick fir barrel style not a donr oven sadly

That means buy time buy materials it go wat over budget

But i would be building a hearty so easy do insulated one and would be putting least 2-3in loose vermaculite around full oven

i was looking at the red frogged brick again. some of them are cracking and bit rought so not sure them would hold up to heath

was going lay them flat on side for floor, then as lay each down fill the frog section with vermaculite or other heat retaining or insulating material. then terracotta tiles on top these for cooking floor.

Dome i was going to split bricks with 9inch grinder and diamond blade.

Re: My Brick Selection ok?

Normally the side opposite the frog will be a scraped finish, i.e. pretty rough. Laid on their side and filled with non-insulating material would be better.

Re: My Brick Selection ok?

Using a grinder and a diamond wheel is an option but there is going to be a ton of dust. Fabby just recently did a build with snapped headers something you may want to consider if you do not have access to a wet saw. You can save the grinder and diamond wheel for the bricks that need more work than being snapped. Just a thought.

Re: My Brick Selection ok?

i will happily use a bolster and chisel. can get consaw too if want with hose attached but rather not as hevy to use on small bricks

if bolster and chisel works then i will use it for the bricks that are not seen

bricks with frog. fill with vermacrete or a high temp concrete like that used for bonding the dome bricks.

i was going lay red brick with the narrow side laying down so frog faces sideway. then tiles for smooth cooking floor.

also whats this???? looks like vermaculite premix. would this do as hearth and render for finish?

Re: My Brick Selection ok?

just spotted this on the pdf file for forno oven. this mean the fire bricks i have are prob not suitable?

High duty fire brick.
These brick have very high alumina content (60% or more),
get very hot (1500?C and up) and are designed for continual
high-heat applications, such as furnaces. They are
expensive, and will get too hot for cooking food. In general,
pizza wants heat between 750F and 900F, while bread and
roasts cooks best between 500F and 600F. (Note that brick
ovens are able to cook at higher temperatures without
burning because of the moist heat inside the oven and
shorter cooking times.)
