Review: Fast Delivery, Good Quality & a Good Price! - 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! 👍
Review: Good Stuff! - 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.

### ⭐⭐⭐⭐⭐ Awesome Fire bricks!! Great product!!!
*by A***R on April 1, 2025*

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.
