The tantalizing scent of pizza fills your nostrils as your eyes focus on its brick oven source – a delicious reminder that this is truly authentic Italian cuisine!

Firebricks come in an array of shapes and dimensions, used for the lining of furnaces, fireplaces, and stoves – plus they take pizza ovens to a sumptuous new level!

Firebricks are specially designed for lining fireplaces, stoves, furnaces in both residential and industrial settings. Even though it’s not an immutable rule to use these bricks when building a pizza oven, consumers and professional chefs highly recommend using them due to their heat-resistant quality.

What are Fire Bricks?

Firebricks are a unique type of refractory material that can withstand the highest temperatures. They are used by chefs, artisans, and other professionals to line kilns, ovens, stoves, and furnaces for greater energy efficiency than regular bricks due to their low thermal conductivity. Moreover, firebricks have great applications in both fireplaces and forging projects alike!

Why Fire Bricks Are Necessary?

For tasks and appliances that require enduring high-temperature settings, firebricks are the necessary solution. Firebrick is composed of refractory ceramic material which differs from traditional bricks used in sidewalks or driveways. This specialized brick can withstand intense heat environments not achievable with other building materials.

Firebricks are the ideal choice to protect your stove’s steel sides, as their exceptional insulating and heat-retaining properties keep high temperatures within the firebox to prevent them from leaking out. Furthermore, these bricks provide a number of additional advantages:

  • – With superior heat retention, you’ll never have to worry about burnt pizza, pastries, and other baked goods again.
  • – Through reflection, more light is captured and directed into the oven fire to expedite cooking.
  • – When it comes to pizza ovens, Firebrick offers a truly classic experience with its authentic design.
  • Firebricks are free from any hazardous chemicals, making them a safe choice for use in various projects.

What to Look for When Buying Fire Bricks?

When selecting wood stove fire bricks, there are several variables to consider. In particular:

Go Hard or Go Soft?

Fire bricks come in both soft and hard varieties. Hard fire bricks are incredibly resilient, dense, and perfect for chimneys, kilns, fireboxes, and burner ports. On the other hand, soft firebricks are composed of refractory components that contain combustible materials; making them lightweight yet highly effective as liners that can withstand extreme temperatures from 2000°F to 3300°F!


Fire clay, used in the manufacture of firebricks, contains alumina and silica. These two elements give it its ability to absorb high-temperature levels. You’ll find that hard bricks can be found with different grades including:

  • – Low-Duty: Reliably endure temperatures of up to 1,750ºF while providing 24-26% alumina. Yes, this material is perfect for fireplace chimneys.
  • – Medium-Duty: Constructed with 34-38% alumina, this robust material is suitable for low-temperature ceramics kilns and flues. It can resist temperatures up to an incredible 2,700ºF!
  • – High-Duty: Boasting an alumina content of 36-40%, this special material can handle temperatures up to 2,850°F, making it ideal for chimneys, backup linings, and boilers as well as ceramic kilns.


9 x 4.5 x 2.5 inches is the dimension of a typical refractory brick, available in various shapes such as:

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

Selecting the shape and size that is right for your needs depends on what you intend to use the fire bricks for. For example, insulating firebricks can be easily cut by hand with a saw while hard bricks require specialized equipment. Consider precisely why you need these bricks; decide which form best accommodates that purpose, then make your selection!

What Fire Bricks are the Best for Pizza Ovens?

If you’re searching for fire bricks to fit in your pizza oven, look no further than clay and kiln-fired options. These are the ideal choice to unlock your inner pizza-baking wizardry as they can withstand the intense heat inside a pizza oven – something concrete bricks simply cannot do.

Don’t worry about your fire bricks, even if you own a low-duty grade–they are designed to withstand temperatures up to 1,000°F and more! Now you can rest easy knowing that your pizza oven can reach scorchingly hot temperatures without causing any damage.


For pizza lovers, there are few pleasures that can compare to the taste of homemade fire-baked goodness. Fire bricks for wood-fired ovens hold heat extremely well even with a relatively small flame and will cook large batches without costing an arm and a leg – typically ranging from $1-$3 per brick!

If you’re pondering the amount to invest in fire bricks, then be overjoyed when you discover their affordability. As we’ve mentioned earlier regarding woodstove fire bricks, there’s no doubt that a brick pizza oven is a right choice for you.
