    Once they start to degrade, they can actually self-ignite (chemical process). You can't stop the fire on them and can only hope to stop the fire in whatever is nearby. The best way to dispose of them is to burn them in a controlled way before they catch your house on fire.
    The same base was used for early motion pictures and there were several movie theater fires because of it (though, granted, the films were being lit by pretty hot lights for projection at the time).

    Here's the best site I've found for how to test and store old negs - http://www.nedcc.org/free-resources/...nd-duplication In case anyone else comes across this thread while looking for info.

    Bethe, you know it, but I would like to emphasize that nitrate film produces toxic gas when burning. One reason more to be carefull when doing so.

    I have a large back yard (2 acres). I'm also working on rigging something up so I'll be standing a few feet away using a long match and not holding the neg. It does come in handy being the daughter of an engineer - something genetic in the thought processes, I think. Something for others to consider, though.

    (And this is yet another time I miss being at the lab and having a fume hood handy, not to mention the chemicals).

    If you're that worried about a fire, I believe I'd buy a cheap safe and keep them in there. I realize nitrate film is much like guncotton, but it's not nitroglycerine. Of course everybody is the measurer of his own safety. At the same time we do live now in a society of alarmists. I guess my point is, if you don't extract the highest possible image off these films now, once they're burned you won't get a do-over. GL

    Strike what I said earlier. Have a look at this interesting link:

    This is aimed at tightly rolled film, as most what one can read on this issue.

    I wouldn't sweat this. Just burn a small portion, collect the data, and move forward with whatever choice. Burning a small clip is not going to result in a toxic disaster or immediate risk.
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    That burning was about letting burn the whole lot after reproduction.

    I see no need to burn it at all. Segregate the nitrate into a biscuit tin with a couple vent holes and keep it under 38C/100F. It's survived a century in a hot house, it'll be fine for the move as long as you don't leave it locked in a steel shipping container out in the sun. We're not talking about 5000 feet tightly wound, with much higher concentrations of gas and the dense packing causing self-heating from (and therefore acceleration of) decomposition.

    Here's one from the pile of envelopes (with about 7-12 each) in a wrap labeled "1912 Europe" (he was married in 1912). I really like this one for some reason. Most of the others so far aren't as interesting (and maybe my great-grandmother took this one instead - she was a painter as well as a bacteriologist). This is on the larger roll film (mentioned earlier, film about 90mm wide, image 83mm x 140mm).

    I haven't done any others from this group, yet, I've been doing the baby pictures and shots of my grandmother and her sisters. There's also a trip to England (and maybe more) on smaller film from the 30s.
