Re: conservation of albumen

Coated paper will last indefinitely.

Sensitized paper, at most 24 hours and you will see it start to fog.  

Determining whether your albumen solution has gone bad is a subjective process looking for a bad smell, as opposed to the normal smell of the albumen, and if you see anything floating in the solution it is usually a good clue to dump it.

I've never used a solution more than a couple weeks or so old with the clock starting once the fermentation process has completed, according to the Reilly timetable.  I keep the solution refrigerated for the entire time it's not in use as well as the fermentation time, and not frozen.

Why not mixing in batches, just enough to coat the needed amount of
sheets? (Like say... 40 11x16" - quarter size - sheets at a time.)
Albumenized papers can be stored for much longer than a year...
