I use these in my fireplace and I love how they retain heat.

Good product and made with quality. Very good for the price. Bought these to use in wood burner to prop wood up and works great

These are heavy bricks. Not the light ones you can cut with a saw. I had to look at its weight to make sure it wasn’t the light ones heavy fire bricks not east to cut.

It works exceptionally good. It keeps your places nice and hot. It’s very safe as well

Very sturdy and as pictured.

Very nice fire bricks. Only reason for 4 out of 5 stars is they were a little chipped up when they arrived. Came well packed in a foam box inside the cardboard box. Must have had a very rough ride to me. Maybe dropped a couple of times. They will still work as fire bricks. Just do not look great with the corners all chipped up.

I put two bricks in my cat's litter box so that he will not knock it over. These were ideal and heavy for the way that I needed to use them.

These are not “normal” firebricks. What they really are is heavy full clay bricks. You have to use a concrete saw to cut them. In terms of weight, they are very heavy. Instead of paying $20+ dollars I could have paid $2 by purchasing regular bricks or pavers at the home store. Don’t be fooled like I was!
