    I don’t know if we can call it chemistry but quenching steel.

    In high school I was doing blacksmithing and so quenching the blade was part of the process, probably my favorite part.

    Heating the blade above 800°C and dipping it in oil, with the oil instantly catching fire was always very dramatic.
