    Frozen Chemistry

    I have a darkroom in my garage, and while it rarely freezes where I am, It does get very cold, and on occasion will freeze. Does anyone know of any issues with chemistry exposed to temperature variations such as this. I would also wonder about the summer when the chemistry will be over 90 and have to be cooled for use.

    I wonder if I should keep the chemistry in the house and onlyu take it out to the darkroom for use.

    * When the film you put in the camera is worth more than the camera you put the film in... *
    * When I started using 8x10, it amazed me how many shots were close to the car. *

    I've never had chems freeze, but everything I've read on these here forums says you should not do this. The componants may/will come out of solution and not go back in.

    Jim is exactly right. Also be aware that the freezing point of various chemicals is not always the same as the freezing point of water. For example, the freezing point of glacial acetic acid is 15 degrees (high 50s in the old reckoning).

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    I have stored dektol in the freezer. It comes out of solution but when you warm it up and give it a stir it goes right back in. I also store my bottle of Glycin powder in the freezer.

    It's not advisable some crystallisation will take place and it can be a problem getting the solution to re-dissolve properly. You could use a very low powered heater to keep the temperature falling below freezing. Or as you suggest store the chemicals elsewhere during very cold spells.

    Keep your lenses in the house, at low temperatures moisture can creep inside and if the lenses are used without careful warming up you'll get condensation on the inner glass surfaces.

    Color chemistry (E6) should not be frozen, according to Kodak. You could put them in a cabinet and use a space heater to keep it at 60.

    I froze my mixed E6 chemistry at the suggestion of someone in these forums who insisted that it was the way to go. Unfortunately, it ruined the chemistry and an entire batch of film. Never again!

    Freezing chemistry or allowing it to freeze is a bad idea. Not going back into solution properly is only one reason, but after one reason, why would anyone need more reasons.

    If playing in traffic will get you killed, that should be enough reason not to play in traffic. Of course taking you out of the gene pool could be a good reason for you to play in traffic.

    Research your chemicals to make sure. Some chemistry, upon freezing, will seperate and are not remixable.
    Thank you.
