12 Pieces Insulating Fire Brick for Ovens, Kilns, Blacksmith, Fireplaces, Forges 9" x 4.5" x 1.25" 2300F Rated Insulating Fire Bricks

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! 👍

I have used these in a open fire lump charcoal outdoor grill for 6 months. They work great, easy to install they are in the bottom of the grill subjected to intense heat. No issues what so ever! I do have a coal/grate pan underneath the grill grates for the charcoal. Helps to clean ash and coal residue. They are a bit brittle if you are rough with then but mine are laid on a level surface. Dont pound on them as they will break!! No hammers allowed lol. Highly recommend.

Bricks are packed really well, little chance they will be broken in transit. I am using them in for forge doors right now and they are doing a great job. Inside gets super heated, outside stays cool.

These worked great for our outside fire pit. We lined the bottom on top of the concrete to protect it from cracking. Then added lava rock on top. I use a single layer to go around the inside of the concrete retaining wall blocks. They break fairly easily by hand.

Nice. They are lightweight but I'm wondering if that changes over time.

The media could not be loaded. I waited till after the season to review. Worked as expected. Easy to put in.

Easily cut to fit.

these are very porous and lightweight. i was too lazy to go to the outdoor store and got these delivered instead for the same price. same size as my others, but half the quality and density. my fault for buying sight unseen and being too lazy to drive 20 miles. they did arrive well packaged and in good shape at least
