Firebrick suitable for pizza ovens

Re: Firebrick suitable for pizza ovens

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.

Thanks dmun. The shapes as illustrated are beyond our manufacturing capabilities.

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.

Re: Firebrick suitable for pizza ovens

That brick would be easy to build a 31" oven with, huh? Is there room for mortar between them?

Re: Firebrick suitable for pizza ovens

Better yet can we specify a reasonable angle?

Re: Firebrick suitable for pizza ovens

There are two sizes in the photo. The first is a No #2 Arch. It measures roughly 8-1/4 x 4 x 2-3/8 to 1-5/8. The second is a No #1 Arch that measures 8-1/4 x 4 x 3 to 2-5/8. The radius shown was achieved by alternating the two sizes. Using just the No #2 Arch approximately an 18-inch inside radius can be achieved.

In fireplace construction we recommend mortar joints of 1/8-inch for firebox construction. Using a similar joint in the arch shown would add a bit to the overall size, but I wouldn't think it would be significant.

There are a couple standard industry angles. One of them is likely close to something reasonable for pizza oven use. What's most advantageous?

Can you post your list prices for the bricks? It will give a perspective on "not terribly more expensive....thanks!

Re: Firebrick suitable for pizza ovens

Freight is a huge factor in the price of low-duty firebrick, but I would expect the two arches to be in the neighborhood of $1.20/each in pallet quantities if sourced through a masonry supply dealer moving material in truckload quantities.

If they were to be mixed and matched on a pallet and drop shipped to a private residence the price could be as high as $5-7.50/each depending on location. The difference being freight, and convenience.
