I am going to be exploring Albumin printing for the first time as soon
as some chemicals arrive. As a beginner, I will be following Mike
Robinson's "21 Easy Steps To Albumen Printing" guide.
But I have a couple of questions:
1. How long can the Albumen mixture be stored in the refrigerator before
it goes bad? Would freezing it in aliquots prolong its life or damage
it?
2. I will be using sunlight for the initial printing. Having done
cyanotypes in the past, I have found that the glass, paper and negative
sandwich gets quite hot, especially when it is 100+ F outside. Will this
heat absorption be detrimental to the albumen or negative? Would adding
a heat-absorbing glass plate be useful?
Any insights will be welcome. Thanks.
