Insa-4 Lightweight & Insulating Fire Bricks - 2500F Pack of 4 - Size 9" x 4.5" x 2.5" - Fireclay, Chamotte Firebricks for Ovens, Forges, Kilns, Fireplaces, Wood Stoves, Steel Furnaces

Works as intended, easy to setup for my smoker firebox, have been used quite a bit and still like new, Fit good (all same exact size). Helped take up dead space in the oversized firebox, used less wood, and maintained a more constant temp throughout the cook.

Delivered in excellent condition . No cracks or breaks.

Bought a clay chiminea. Manufacturer recommended putting gravel and fire bricks at the base. The bricks are working great!

Works great so far

Need a grate for a small fireplace..... Wallah :)

I made a mini forge using these 2 bricks, cut out a hollow inside and added a hole for the blowtorch, it kept the heat in enough to harden some 1095 steel so I am happy with the result.

I used them to make a small knife forge. They work, but cracked on first gradual heating. It still works, but cannot be moved.

Received then in good shape. Weren’t busted up, packaged good. Using them to do my brazing on.
