By Robert Parsons January 5, 2022

When you think of a classic pizza restaurant with authentic Italian cuisine and authentic, traditional style, what do you picture? 

You may see a black and white checkered tiled floor. Perhaps some traditional wooden dining chairs and tables come into view. Somewhere on the walls, there’s an Italian flag. Wafting throughout the space, you smell the aroma of delicious pizza. And the oven from which it comes? You see that it’s made of brick, of course.

Coming in all sorts of different shapes and sizes, fire bricks are utilized for lining furnaces, fireplaces, and stoves. And when they’re used in pizza ovens, the cooking experience, and food quality are taken to a completely new level! In a single bite, most people can tell the difference between pizza made in a brick oven as opposed to one baked in a regular oven. Of course, we’re talking about the delicious smokey flavor, which is only possible with an oven built with firebrick.

The key differentiating factor between regular bricks and fire bricks is that fire bricks can withstand extreme temperatures while regular ones simply cannot. They are specifically designed with the intent to line the inside of fireplaces, stoves, or furnaces in both domestic and industrial capacities. And while it’s not technically required to use fire bricks for pizza ovens, it’s highly recommended by both consumers and professional chefs to do so.

What are Fire Bricks?

Using refractory materials, Firebricks are constructed and designed to stand up to extreme temperatures. Artisans and cooks from all walks of life use these special bricks to line the insides of kilns, furnaces, ovens, stoves, and so forth. Due to their low thermal conductivity, firebricks offer greater energy efficiency, which makes them excellent for fireplaces and forging, as well.


Why Should You Use Fire Bricks?

There are numerous activities, projects, and practices that may require someone to use firebricks. Unlike traditional bricks and refractory cement, firebrick withstands incredibly high heat environments. What makes these bricks different from those used to line sidewalks or driveways, for example, is the fact that they are composed of refractory ceramic material.

Due to their brilliant insulating and heat retentive properties, firebricks are ideal to ensure the steel sides of your stove remain protected. It does this by trapping high heat within the firebox, thus preventing it from slipping to the oven’s sides. Firebrick also offers the following benefits:

  • – Better heat retention – Pizza, pastries, and other baked goods are less likely to burn.
  • – Reflection – More light is reflected into the oven fire, which supports quicker cooking.
  • – Authentic – Firebrick is more traditional, especially when it comes to pizza ovens.
  • – Chemicals – Firebricks do not contain any toxic additives. 

Things to Consider When Buying Fire Bricks?

There are a few things you want to consider when it comes down to wood stove fire bricks. For instance: 

Hard and Soft

Fire bricks are either soft, or they are hard. 

Hard bricks are durable, very dense, and excellent for chimneys, large kilns, fireboxes, and burner ports.

Soft bricks are lighter in weight and are composed of refractory components that contain combustible materials. When fired, soft bricks offer fantastic insulation and are typically used as liners that withstand temperatures from 2,000°F to 3,300°F. 


Fire clay, used to make firebricks, contains alumina and silica, which allow it to sustain high heats. You’ll notice that hard bricks are offered in varying grades, such as:

  • – Low-Duty: Contains 24-26% alumina. Used for fireplace chimneys and withstands temps up to 1,750ºF.
  • – Medium-Duty: Contains 34-38% alumina. Used for low-temp ceramic kilns and chimneys and withstands temperatures up to 2,700ºF.
  • – High-Duty: Contains 36-40% alumina. Used for chimneys, backup linings, boilers, and ceramic kilns. It can withstand temperatures up to 2,850ºF. 


The standard size of a refractory brick is 9 x 4.5 x 2.5 inches, and they commonly come in the following shapes:

  • – Straights
  • – Soaps
  • – Splits
  • – Arch
  • – Wedge

The shape and size that suit your needs best depend on what you want to use the fire bricks. Firebricks that insulate can easily be cut using a saw, while hard bricks cannot be cut without the use of special equipment. So, when you’re making your decision, think about what you would like to use your fire bricks for, decide which shape best fits that need, and go from there!


What are the Best Fire Bricks for Pizza Ovens?

If you’re on the prowl for fire bricks specifically for your pizza oven, you’ll want to avoid concrete options. Bricks of the clay and kiln-fired variety are ideal for pizza-baking magic, as these can handle the intense temperatures inside pizza ovens, while concrete ones cannot.

Even though pizza ovens can reach blazing temperatures up to nearly 1,000°F, you won’t have to worry about your fire bricks. Even ones that are of a low-duty grade can handle temperatures higher than that! 



Not a lot of things can beat fresh, delicious homemade pizza baked in a wood-fired pizza oven. Even with a relatively small fire, fire bricks for pizza ovens can heat up large capacities and hold heat for lengthy periods of time, making it economical.

Plus, if you’re wondering, “how much do fire bricks cost?”, you’ll be relieved to know that you can get them for $1 to $3 per brick, making them an affordable choice that will give you the value for your hard-earned money.

When you take into account everything we’ve mentioned about woodstove fire bricks, you’ll know you simply can’t go wrong with purchasing a brick pizza oven. Be sure to explore our top 3 best picks!
