Firebricks are blocks of refractory ceramic materials used to line fireplaces, fire boxes and furnaces. They are different from regular masonry bricks because of their ability to withstand temperatures up to 1,800 degrees Fahrenheit. The chemical composition of dense firebricks is different from that of regular bricks.
Are there different types of fire bricks?
There are two types of firebrick: hard brick and soft brick. Hard bricks are very dense and durable and used for their structural qualities. They can be found most often as the main building component of large kilns, chimneys, fireboxes and burner ports—anywhere around direct flame.
What makes a brick a fire brick?
A fire brick is a special type of brick made using fire clay and has a good resistance against high temperatures which are used in kilns, lining furnaces, fireplaces and fireboxes.
What can I use instead of fire bricks?

How do you identify fire bricks?
Firebricks are commonly whitish or pale yellow, though there may be other colors. They will be very exact in dimensions and edges, though used ones may have chips and ragged edges. You don’t want any bricks that have a series of holes through them; that is an indication (not the only one) of newer hard common bricks.
How can you tell the difference between building bricks and refractory bricks?
The main function of the thermal insulation brick is to keep warm and reduce the loss of heat. The thermal insulation brick generally does not directly contact the flame, and the refractory brick generally contacts the flame directly. Refractory bricks are mainly used to withstand the flame roasting.
Can you use fire brick outside?
Brick Fire Pit In Your Garden
Not only are they stylish but also practical and provide a place to gather together outdoors. Fire bricks can be used to create enticing and fully functional fire pits in your garden.
Are fire bricks expensive?

How long do fire bricks last?
Base/baffle bricks- indefinitely or til a dumb move by me. Back bricks- first aggressive load technique (could be first year, could last 30yrs). Stoves that use firebricks as part of the baffle system are nice; easy to replace but rarely need replacement.
Why do fire bricks crack?
Stove liners may become cracked after sustained burning at very high running temperatures, or if the liners become damp and are subjected to a high burn rate without a period of slower firing.
Can any brick be a fire brick?
Substitute for firebricks can be old red clay solid bricks. In ovens these alternative red clay bricks will heat up, retain heat, cook, bake, roast, re-fire, absorb conduct store and hold the heat from wood fire and perform the same way as proper refractory firebricks do.
Are fire bricks brittle?
While ‘normal’ bricks can withstand quite high temperatures, they do vary widely. With fire bricks you can be sure that your bricks aren’t going to crack or become brittle with on-going use.
Are all bricks fire proof?
As bricks are made in a fire kiln, they’re already highly resistant to fire. However, it’s true that individual bricks are much more fire-resistant than a brick wall. A brick wall is held together with mortar, which is less effective.
Can house bricks be used for a fire pit?
Fire pits can reach high temperatures, so regular bricks won’t work. Regular bricks will crack at high temperatures and can cause a real accident if used in fire pits.
Will bricks explode in a fire pit?
Bricks are usually quite porous, and explosions will result from the rapid heating of water trapped in the bricks, which causes pressure build-up. If the pressure is enough, the brick might explode. In most cases, however, bricks will crack and pop in a fire pit.
Can you use red bricks for a pizza oven?
If the bricks are made of clay and are kiln fired (firebrick or red clay brick) they can be used for a pizza oven, but if they are concrete bricks you should stay away. Clay bricks can withstand the heat from a pizza oven, and concrete bricks can’t.
Why brick oven pizza is better?
Higher Cooking Temperature
The oven bottom stays a little cooler, but the top of the oven up to the dome gets very hot — up to 660 degrees Fahrenheit. The consistency of the fire keeps the temperature up, so everything is cooked uniformly. There’s no part of the oven — or the pizza — that gets less heat.
Why are pizza ovens dome shaped?
The dome shape is designed to efficiently absorb heat from a wood fire, and to evenly reflect stored heat, and heat from a live fire inside the oven, down to the cooking surface.
What is the floor of a pizza oven made of?
Brick Oven Cooking Surface. Your cooking floor can be made from either individual firebricks, set in an offset (graphic 1) or herringbone pattern, where the oven walls rest directly on the cooking surface, or from a round refractory floor provided by Forno Bravo. Either works.
How thick should a concrete slab be for a pizza oven?
To support your oven stand you need a reinforced concrete foundation, which should be no less than 112mm thick. Why so thick? It’s all about ‘concrete cover’ – steel reinforcing requires a minimum of 40mm of concrete between it and the air/ground to protect it from corrosion.

Using Concrete Is a Bad Idea
You may not have spare clay bricks lying around, but you might have concrete blocks. Unfortunately, these aren’t going to cut it. These aren’t fired and so haven’t been hardened. They’re very brittle and would crack easily under the heat.
Are concrete bricks fireproof?
Concrete block can withstand high temperatures and water pressure from fire hoses better than other materials deemed fire resistant such as fiber-reinforced gypsum panels.
What is the best base for a pizza oven?
The base – solid foundations
Supports for your outdoor pizza oven can be made of concrete, breeze blocks, house bricks, or even old railway sleepers, but they must be strong and level, as the oven is going to be heavy. If you are using bricks or breeze blocks connect them together using cement.

Can you cook in an outdoor fireplace?
With a masonry outdoor fireplace you can sink this heat into the bricks and concrete allowing you to achieve much higher temperatures than you can in a steel oven. For example, it’s easy to cook pizza at 350 – 400°c in a Flare Fire compared to your kitchen oven which at best can achieve 250°c.
Can a pizza oven double as a fireplace?
Besides all that, the pizza oven comes with an optional pizza table, so you can prepare all ingredients at the same worktop, without any hassle. When you’re done with cooking, the same oven can be used as open fireplace in the garden, making your long summer evenings more comfortable and cozy.
