Good Lord! What would you be burning so hot that would make concrete explode? Rocket fuel? NO, these bricks will not explode if you're burning wood.

Make sur eit dries about a week plus before using it the build small fires 4-6 of them to help cure it completely.

Was this Answer Helpful ?Line the inside of the pit with lava rock or sand up to the bottom of the fire ring. This will protect the rocks themselves from any direct heat. They shouldn't explode when exposed to flame, but will fall apart given time. Protect them and either purchase a deeper steel ring or line the inside of the pit with sand or rock.
