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

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.

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

Very sturdy and as pictured.

Great fire brick. I double the base (two stacked bricks ) for silver smithing. Works great. However, Can't "pin" works as too firm. Otherwise great, using acetaline and brick coils quickly.

Came badly chipped. Poorly made and packaged.

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.
