    question on old(ish) fix....

    I have been given a gift:

    19 bottles, each containing 5 liters of concentrated fix.

    Nice, when you have students!!

    There are two different ones, and I know them both.

    about half of them are Agefix, and there's nothing wrong with those ones...

    But the second half is Tetenal Superfix, (a fix I normally use) and inthose bottles, a sediment seems to have formed in the bottom of the bottles...

    Is the fix unusable - can I heat up the fix, and then make the sediment "go back" to original state?

    Someone must know.

    I don't

    Your nose should tell you : give that Tetenal a good sniff.
    If a nasty sulpherous stench - it's doubtful/dead. Dilute some and test with film leader ,compared with the Agfa.
    If it clears in good time I would trust it.
    Filter off the clear portion.
    I think it's kaput though.

    I used to get Kodafix bottles that were left behind by students in a community darkroom.
    I ended up with some that sat for maybe 5-6 years and had some "flakey" material that I surmise was sulphur.

    Long story short, I filtered the gunk out and used it. I always did clip tests for clearing time to calm my paranoid nerves.

    Bottom line, I wouldn't use it on any really serious/critical work.
    I wouldn't trust the archival property.

    hmm - thank you.

    I have read somewhere, that if this occurs in colour bleach/fix, a heating can make it as new again...

    hence my question on heating

    if you use a 2 bath system,
    you could probably filter out the sediment
    and use THAT fix as your first bath ( after your clip test )
    and " good-stuff " for your second bath.
