How do you cut fire bricks? Step-by-step guide!

Well, let me tell you, a while back I had this little project where I needed to cut some fire bricks. I did a search for “how do you cut fire bricks” and got some information, but let me share my own experience with you. I was building a small pizza oven in my backyard – yeah, I know, pretty ambitious – and those fire bricks are a key part of it. At first, I thought, “How hard can it be?” Turns out, cutting these things is a bit of a process, but nothing we can’t handle.

First off, I gathered my tools. Now, you don’t need anything too fancy. I used an old saw I had lying around. The key thing is, don’t use your best saw for this. It’ll get dull real quick. Some folks online said to use a masonry blade or a wet saw, but I didn’t have those, and honestly, I didn’t want to spend extra money. Also, a chisel and hammer can do the job, but it’s not as clean. I heard that soaking the bricks in water for a minute helps with the dust, so I did that. Set up a bucket of water right there and dunked each brick before cutting.

How do you cut fire bricks? Step-by-step guide!

Get Started

  • Get Your Bricks Wet: Like I said, I soaked each brick for about a minute. Made a big difference with the dust.
  • Mark Your Cut: I used a pencil and a straight edge to mark where I wanted to cut. Measure twice, cut once, you know the drill.

Cutting

  • Start Sawing: I just used a regular old saw, I found it better to score the brick first. I sawed along the line I marked, just enough to make a groove. Then I went a bit deeper, maybe a quarter of an inch.
  • Keep Going: I kept sawing back and forth, deepening the groove little by little. Patience is key here. Don’t try to cut through all at once, or you’ll end up with a mess.
  • Flip and Repeat: Once I had a decent groove on one side, I flipped the brick and did the same on the other side. This helps to get a cleaner break.

The final step was a bit tricky. With a good groove on both sides, I placed the brick on a soft surface – some old rags in my case – and gave it a firm tap with a hammer along the cut line. It broke pretty cleanly, I must say. If it doesn’t break, just keep sawing a bit more on each side and try again.

I won’t lie, it took some time and elbow grease. But by the end of it, I had all the bricks cut to size for my pizza oven. And let me tell you, that first pizza baked in an oven I built myself? Totally worth the effort. So, if I can do it, you can too. Just take your time, be patient, and don’t be afraid to get a little dusty.
