How do I use fire bricks for pizza oven?

The first step is to make sure your fire brick is either new or clean before using it because dirt could cause problems with its insulation properties. If your fire bricks are dirty or cracked, replace them.

It’s also important to know where you plan on placing the fire brick in your oven. Ensure the area is not prone to smoke and heat because these could add unnecessary cleaning tasks for you later on.

Once it’s clean and properly placed, just layout your fire brick in the shape of a half-moon or cut it into any custom shapes that fit into your oven; you can also stack them if space is limited in your range.

Then all you have to do is place the baking sheet (with the dough, etc.) on top and bake like usual!


What materials are used for fire bricks for pizza oven?

Different types of fire bricks are made from other materials, including:

Clinkers: Most commonly found clinker firebricks are ceramic refractory bricks made primarily from clay and silica sand.

Lava: Lava firebricks are used in high-temperature insulation projects, including pipe flues, furnace linings, kiln partitions, and ovens.

Flux (Silica) – This common type is made of sand or rocks that contain little to no fluxing elements like feldspar. It also has less than 4% alumina.

Slag: Slag firebricks are made by adding ground granulated blast-furnace slag into the clinker mix, which gives it a dark gray color instead of the usual tan color of regular clinkers.

Why should I use fire bricks?

There are many reasons why you should consider using fire bricks in your oven’s liner:

  1. They offer superior insulation compared to other materials like cast iron and plain steel.
  2. They can withstand temperatures up to 3000 degrees Fahrenheit, which makes them perfect for baking.
  3. If you’re looking for a way to make pizza dough crispy, line your oven with fire bricks and bake the crust directly on top of them!

Now that you know what these fire brick options are and how to use them, there will be no limit to the type of pizzas and bread you can make! Just remember not to put anything flammable (like seeds or nuts) directly on top of the bricks because it could catch fire.

It would help if you also waited until your oven had reached its maximum cooking temperature before using the bricks.

Why are fire bricks great for pizza ovens?

The heat retention properties of fire bricks for pizza oven allow for a longer cooking time, important when you’re making a thicker crust pizza. They also help maintain even heat distribution throughout to keep your pizzas from getting burnt.

Pros and cons of using fire bricks


  • Fire bricks offer superior heat insulation.
  • You can evenly cook thicker crust pizzas because of their high heat retention abilities.
  • Baking directly on the bricks gives your pizza a nice crispy bottom crust.


  • If not adequately dried, fire bricks can hold water which could turn into steam and crack them over time. Water also leads to much higher chances that your oven will explode! Make sure you keep your oven-dry before adding the bricks inside.
  • Fire bricks are very fragile, so it’s essential to handle them with care when using or to handle them.

Best Fire Bricks for pizza ovens

There are many options when it comes to fire bricks, but they all come down to a few things:

What is the heat retention capacity of your fire brick? How thick is it? What is its insulation quality? Will it last long in high temperatures? And how much does it cost?

As a general rule of thumb, the more insulation your fire brick has, the more expensive it will be. But don’t worry because we’ve listed some affordable options here which perform just as well as the pricier ones!

Red Bricks: A popular option for oven liners because of their high insulation properties, they hold the heat very well and, at the same time, distribute it evenly throughout your oven. These bricks are especially great for thicker crust pizzas and bread.

Blue Bricks: They’re made using a special clay that’s designed to withstand high levels of heat, making them great for use in ovens and fireplaces.

The blue color comes from anthracite coal which is added to the clay mix. This type of brick offers good insulation qualities but is not as good as red bricks’ so if you plan on cooking thinner crust foods like pizza or want something faster, then go with red bricks.

White Fire Bricks: Like blue firebricks, white ones contain anthracite coal, giving them their white color and heat resistance properties. Because of their low cost, these are the best fire bricks for starting up your pizza oven!

Onyx Bricks: These are similar to blue bricks, but they’re not made with coal, so they don’t have that particular white color. They’re usually more expensive than blue ones but less than red bricks, which is why they make an excellent middle-range option.

Plus, if you want to get creative, onyx bricks can be painted any color, so you could even use them as decoration in your home!

Why you should be using fire bricks for pizza oven?

Retain heat better & release heat slower

This is because bricks contain voids in their structure which absorb heat and release it when needed. The same goes for drinking coldness when you want to turn off your oven or smoker. When the temperature drops, the brick will still retain some of its heat due to these holes.

Work great with dense foods.

Bricks are perfect if you want a nice thick crust on your pizzas! Even without cheese melted on top of it, the clay continues baking until all moisture has been cooked out of your food.

Less smoke

Depending on the material, some are less porous than others, which means less smoke will be produced when you cook with them. You can also use a heat deflector if your bricks aren’t doing their job well.

Not only for the oven

These aren’t just good for pizza ovens or commercial ones! You can use blocks around your starter forge or anything else that has high-temperature requirements. They do tend to loosen over time due to pressure, but it’s easy enough to slap some mortar back in place!

The proper way to install fire bricks

Before you get down and dirty, you need to make sure you know how to put these blocks correctly. To begin with, layout the bricks in an area where you want them to stay, with each layer no more than half a foot (15 cm) thick.

After that, start laying mortar around them and put them into place.

Be sure that everything is nice and sturdy before you move on to the next step! If there are any holes left, they can be filled up later on. Mix some mortar using sand once your blocks are fully set; it’ll give you sturdier bricks.

Look for quality materials.

This is very important if you want your oven/smoker to last longer than just one season, so look out for high-quality build materials. No matter how good the material is, they will eventually wear out, so make sure they’re replaceable so you can enjoy using your oven over and over again.

How many fire bricks for pizza oven do I need?

You will want enough blocks so that they all fit snuggly against each other, which means there should be less than 1/4 inch (6.35 mm) between them. It will allow even heat distribution, especially when mixed with sand or another substance that retains heat.

If you have a good amount of room around the block, you need to know how many spaces between blocks. For them to fit correctly, they need to be touching each other without leaving too much space in-between.

To figure out if your oven needs more or fewer blocks, do a little math! You would want the total thickness at the same level as the brickwork going up if it was a brick oven. So divide this by two and add 3/4 inch (1.91 cm) to it, so there’s some playroom when inserting new fire bricks.

Where to buy fire bricks for a pizza oven?

You can find them at almost any hardware store, some online stores, or even on Amazon. Many people tend to go with brick pads as they are easier to install, but it all comes down to preference, so you can choose whichever one suits your needs.


Do I need fire bricks for a pizza oven?

They’re essential for ovens and smokers because they retain heat which will help cook your food faster and more even. The blocks might warp after a few years, but you can always use mortar to fix them again.

What’s the best material?

Fire brick materials are varied, so there is no such thing as ‘the best. Though, they tend to be most efficient when made out of silica, alumina, and ferric oxide.

How do I clean fire bricks?

You need to wash them with warm water until all residue falls off, then let it dry before putting it back into action. You can also scrub any extra dirt or burnt particles using a wire brush or steel wool.

Do I need insulation around my bricks?

No, you don’t just make sure they’re all touching, allowing for an even heat distribution. If you feel like using insulation, it should be placed on the outside of the fire bricks to avoid any airflow.

Can I use them in outdoor ovens?

Yes, but depending on what material your blocks are made out of, they might get damaged by the weather after too long, so take good care of them! To protect them from moisture and corrosion.

How old do my bricks need to be before I can use them?

It won’t affect anything if they’re brand new or have been sitting around collecting dust for a little while. The only thing that matters is that they are still sturdy, are the right size, and have some insulation.

Can I put my bricks in the oven?

Yes, you can, but it’s not recommended. Please make sure they’re fire bricks so they won’t break when being used for this purpose!

You can set them on a baking or pizza stone but make sure there’s some space between them because heat distribution will be different depending on how close together everything is. That way, you’ll get an even roast no matter what type of food you decide to cook.

How many fire bricks do I need for a pizza oven?

You need no exact number since most ovens are built differently, but the more you use, the faster they’ll heat up! The blocks don’t need to touch each other, but they need to be set at an angle instead of flat. Ensure there’s enough room for air to flow underneath them, or your food will take longer to cook.

Some people like adding insulation, too, which is entirely okay if it doesn’t block any airflow. If not, you risk your oven becoming inefficient and won’t produce great results when being used.
