Great for smoker firebox.
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.

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

Does what its supposed to
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.

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