Subsequently, one may also ask, what's the difference between fire brick and regular brick?

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.

Beside above, can you use regular brick for a fire pit? Homeowners can choose among many fire pit designs, which incorporate various materials including metal, rock, masonry block and brick. You can use standard brick and a preformed fire pit bowl to construct a sturdy fire pit that is designed to be moved if necessary.

Furthermore, what can I use instead of fire bricks?

Some alternatives do exist, such as sandstone and soapstone. Refractory concrete is another great heat deterrent as are old red clay bricks. Any of these can be used in place of the firebrick, to warm hearth and home.

What happens to bricks in a fire?

Fire bricks have a low thermal conductivity - meaning heat does not pass through the fire bricks, instead they reflect heat back into the firebox of the heater to ensure a hotter and more efficient burn. Although more durable to a normal brick, the fire bricks within your wood fire will eventually break down over time.
