    It breaks down whether or not you use it, once it's mixed with, or
    exposed to, water. The solid material has to be kept dry and away
    from water vapor too, or it will degrade, visible on the chunks as a
    pale, pasty light greenish yellow coating instead of the original
    dark orangey brown color of active liver of sulphur.. Once you mix
    the solution, you can extend, slightly, the shelf life by keeping it
    in total darkness, and seeing that the container is fully filled,
    minimizing the air space (and oxygen). But even then, it won't last
    all that long. In general, it's best to mix only what you can use the
    same day, maybe two days, and discard it when it looses it's
    activity. Once the color fades, it's not effective.
