I'm thinking purely B&W use on the 6x7.
So the powdered versions keep pretty much forever?
They should, though stick to the older formulas that are more stable.
As long as they are kept cool and dry, there is nothing to start an
oxidizing reaction.
The old Ilford packaging was wonderful, the powder was sealed into vacuum
packed heavy poly bags.
Kodak's foil bags should also be good, though I wonder if the bags
themselves are not slightly reactive.
If you are thinking of buying a lifetime supply, you are going to be using a
deep freeze for storage, keep your dry chemistry in the freezer along with
your film and paper. That should keep things nice.
HC:110 seems pretty stable in it's concentrated form as well. I had a bottle
given to me that had come out of someones basement. It was at least 25 years
old at the time, since the store that has sold it had been closed for that
long.
For fun I gave it a try, and found that it was still as viable as fresh
HC:110.
