Re: conservation of albumen
For sure, when albumen paper was made they were whipping eggs all the day, and the process was like an assembly chain.So, there's no other information about denaturation and long term storage of albumen solution (as I can see/find) in the monograph.
For home-making, the week or more needed to ... the albumen is whay I would prefer to avoid, but I can't because fermentation is needed to destroy glucose. This last is the responsible of the long-term yellowing of albumen prints (Maillard reaction).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...
