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

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

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.

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.

They're great! Work really well. Use them for firing metal clay. Nice to have a thick block so I don't have to fear burning the surface underneath.

Came badly chipped. Poorly made and packaged.

Fortunately, smaller boxes were inside, but if the large box and totally come apart, the smaller boxes had not address to send to us
