    I have an unopened bottle of e6 first developer starter that has an expiration date of mid 2009. What kind of issues could I expect if I try to use this in a replenished system? I actually want to use this to start a tank of Xtol developer for B&W, but I don't want to ruin a batch if this really goes bad.

    The color changes to honey or darker as it goes bad. Straw color means it is fresh.

    I would say it is a straw to very light honey color. Should that be fine for use? I would only need to use it once in the next few days, then it will be discarded.

    Starter should be fine. I've had colour developer replenisher from 2005 that was fine.

    I have heard it both ways, i.e that starter deteriorates with time and losses its potency like a developer would, and the other arguement.

    From my read of the MSDS starters for developers it is mostly inorganics like bromide and maybe a bit of alkali like carbonate.

    Starter works to build up bromide in the fresh solution to make it like a well seasoned developer.

    In a well seasoned tank, the films being processed leave bromide behind as a side product of the development from the silver halide to elemental silver form to make the processed image.
