Firing up the v1.0.0 backyard pizza oven for the first time, I guess I went too hot too fast. Fortunately I can scavenge another rock from work and try again.

    I made a similar mistake once building a fire pit in the yard. Filled it with rocks from a creek nearby. I eventually had to redo the project because every time it got to temp, little bombs went off.

      As added caution to anyone reading this, river rocks can and will explode violently, and have been known to kill or seriously main you depending on where the shrapnel lands. Be safe out there.

        It’s like microwaving an egg. There’s moisture trapped in there, and the gases can only expand a bit before the rock gives.

        Dangerous egg.

        Not just river rocks.

        Grab any random rock, it will explode at a certain temp, and a certain temp raise over time.

        There’s so many factors it’s almost completely impossible to tell when it will happen, but it will happen eventually
