The package was slightly hit on the bottom of the box and resulted in 1 brick being broken. It is Not a problem however, I needed a few half bricks anyways. The bricks are very lightweight and should be just right for closing one end of my forge off. A few others are for resting a piece of metal on the outside of the forge entrance, for stability & support of the longer pieces of steel, with an adjustable height roller stand. I think that these bricks are perfect for their intended usage & price. They should last a few years minimum. With care, who knows how long. I would recommend these bricks to others. They are a good weight, size & the price is right also! A broken one is understandable & not a problem. Note: The second picture is the bottom of the box that shows where the foam insulation board was broken. It only broke 1 brick and it's almost in the middle of the brick. So it's not a problem! I Still Give'em 5 stars! 👍

Nice and light weight compared to the old Style Easy to cut As well

I was building a firewall for an MCM (Mid-Century Modern) fireplace, and these fit the bill. Used some heat-safe mortar and built a wall to protect the rear side of the fireplace. Had a few fires this fall, nothing too hot but they fit the build well and were priced good.

Used to replace the side wall stones in my wood stove. They were a near perfect fit and cut very consistently. I had to saw off a small portion of 1 brick ~.05" to make it fit. Box had dust but all bricks were intact without any chips or cracks, looked well packaged, some plastic might be nice to contain the dust.
