Firebrick suitable for pizza ovens

[RTflorida]

Food for thought...when I fire my oven it is usually up to about 1100 degrees, then let it settle (equalize) down to 900 degrees for pizza, a bit hotter than some, but it works for me. Roasting usually starts with a 500 degree oven which tails off slowly during the bake, finally slow roasting - brisket, ribs, fresh ham shoulder all go in at around 325 degree, keep the door closed and several hrs later you have indescribably delicious meats and side dishes.
I know the brick yard I purchased from described his bricks as being low duty, wire cut bricks for fireplaces, also stated they were for up to 2400 degrees. No issues and I have been firing for about 10 months.

Great work as usual dmun. The arch/dome/flue transition is a subject that causes no end of grief and a kit of this kind must be a plus.

I'm not so sure on the dome keystone as it pre-supposes a perfect dome build and judging by the photos every one seems to be different and 'made to measure'

Thanks dmun. The shapes as illustrated are beyond our manufacturing capabilities. The engineer that designs our dies played around with them a bit, but didn't come up with anything that wasn't prohibitively expensive or possible with our particular process. I'm afraid we can't be of much help in this case.

How about half bricks? It seems that would save a lot of cutting............or am I mistaken.

Inish.
".... and on the third day", etc etc.,but I shan't labour that point.
I reckon it was good that WG Firebrick took the time to even reply.
Because it's such a niche market, only a fool with money to burn would entertain the concept. (And then there's freight, eh.)
In our dreams maybe. Maybe?

Re: firebrick
I was a potter for 20 years, built many kilns. I rarely used mortar, when planning I ordered wedge-arch-key brick. I'm in Oregon now and haven't been able to find a supplier for these shapes to allow building of a dome from refractory, (fire brick).

Tapered firebricks are used in various kiln and furnace applications, and the last time I looked were available in three angles to form three different radii. They are a specialist refractory item, and very expensive. Oddly, different angles have different costs. They are usually available in medium and high duty firebrick. Your local Harbison-Walker distributor should have them.

Once you see the prices, you may want to cut your own.

Interesting....My oven is actually comprised of 15 cast firebrick pieces.

9 identical blocks that form the soldiers and lower dome.
1 dome piece
2 opposite side blocks at the entry
1 lintel
1 transition to chimney
1 chimney section with damper

I've always wondered why this would not make a good kit for the homebuilder. Add stand, hearth and a FBmix mortar!

Wedges and arches are something we do have the capability of making. We used to supply them to the steel industry. Here's a link to a two sizes that are available. Those produced here are low-duty and not terribly more expensive than straights.

This is Great! I've never seen low duty tapered firebricks, let alone affordable ones. Tell me exactly what I'm looking at here:



Are these two different tapers alternating, or one taper alternating with standard firebrick? Do you have an angle or dimensions on the two tapers?

Thanks.
