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

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.

Received quickly and none of the bricks were chipped or cracked. We are using them in our woodstove and it's performing great.

These install easily, but they are quite fragile. I used a wet saw to cut them, and they handled that well, but even a gentle tap to bed them into the mortar cracked two of them. The breaks matched back up fine, but it bears some care in installation. Compared with others, though, the price is right.

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

Good. And can cut and drill on them

Perfect packaging, not a single brick was broken.

These things weigh a ton! Nice quality bricks. We had quite a few that needed replacing and they right in. (Make sure you measure the size of your bricks.) We didn't have to cut any so I can't tell you about that, but they were easy to put in and fit like a charm.

The price and the product was great. Great for lining my shop built stove.
