We use firebrick in fire pits to create a protective barrier for the fire. Our mission is to provide our readers with heater related articles that will help them establish safe areas around their home that are capable of providing added warmth and enjoyment.
We felt that we needed to ask some homeowners, some brick masons, and some fire pit professionals their views on these items.
Our panel of experts educated us on the different fire bricks that are available. They also informed us about which ones were the best fire bricks for fire pits.
They also told us what features the bricks needed to make them great for the different applications these high-temp resistant bricks are capable of.
Reviews of Best Bricks for a Fire Pit

What to Look before Choosing the Best Fire Pit Bricks?
Fire bricks are not all created the same. They have different features and capabilities and before you run out and buy a load of these items you need to familiarize yourself with their features, and the varieties they come in.
The intended use of the brick plays a large part in which bricks are going to be the best ones for you. Some of the common fire brick purposes include:
Pizza oven creation, where you will want the softer insulated fire bricks. If you are building a fire hot enough for forging it would cause bricks designed for pizza oven creation to disintegrate. Pizza oven bricks can not withstand extremely high temperatures.
DIY fire pits or fire rings that will require you to use a brick that has been kiln fired to a temperature of about 27000 F so it can withstand the high heat of the fire without cracking or bursting.
Protection layering is also a use for fire brick. This requires you to use the same heat resistant bricks that you would use to build a fire pit and place them beneath a fire burning appliance or behind a fire burning appliance to stop heat damage or possible combustion.
Thickness and size
The thickness and size of the brick that will best suit your needs will depend on what you are doing with the bricks.
If you are creating a protective barrier under a wood heater you can probably use thinner pieces of brick because the bricks are not going to be the only defense between the heat and your home. The external portion of the heater will serve as a protective barrier as well.
If you are building a fire ring or fire pit for your home then use the thicker pieces of brick because you are establishing the primary heart deterrent that will stop the fire from damaging anything else in or around your home.
The coloration of the brick is important to some people. The color of the brick can make it more attractive or make it blend in better with the décor that you already have in place. Never let the color of a brick sway you unless the brick meets the right heat-protective criteria that you need.
Some fire bits’ construction is reflective. You do not need reflective bricks for most fire pits but they are extremely helpful when you are building brick ovens to cook in.
Frequently Asked Questions
1. What bricks to use for a fire pit?
The bricks used in a fire pit need to be ones that have been fired at a temperature of around 18000F. At that temperature, the produced brick can withstand exposure to the high heat of a fire without cracking or becoming degraded by the heat. Fire brick or landscape bricks that have been kiln fired to make them heat resistant are needed because normal brick can burst if exposed to high heat and shoot particles of brick out causing the potential for injury.
2. How many bricks do I need for a fire pit?
If you intend to build a fire pit that has a 3-foot diameter you are going to need about 80 bricks to complete the project. You will need to split some of the bricks to create smaller pieces that can be fit together to create the circle and fill in any gaps.
3. How to lay bricks in a circle for a fire pit?
You can begin to create a circle by making a plus sign out of bricks in the center of the area that will be inside the circle of bricks. Then take your bricks and go along the outside of this plus sign and create the circle formation. Fill in gaps using smaller broken pieces of brick. After forming the circle, pour a mixture made of river sand and dry cement mix over them to create a solid foundation.
If you are looking for a fire brick for normal home use then consider the Rutland Fire Brick. This brick’s rating makes it suitable to withstand temperatures as high as 27000 F. You can build a fire pit with them, use them under a wood-burning stove to create a heat protection shield. You can also use them behind a wood-burning stove as a heat protection shield.
If you would like a fire brick that appears to be almost white consider the DC Care Soft Insulated fire brick. The construction of the fire brick is best for the creation of cooking places like pizza ovens.
