It is my experience that if you store your Collodion properly (cool and dark) then it last far longer than much of the literature suggests. John Coffer states in his manual - specifically about the #7 for Negatives - that it is useful for maybe 2 months at most, and my experience clearly defies that statement. And yes - I did varnish the plates I made that day using year-old #7, and the varnish did NOT dissolve the collodion. It is also my impression that older collodion has much better contrast as it ages, which can be a plus.
