DEAR ERIC,
My box of POP fogged after less than a year, left on the shelf.
I forgot to freeze it as recommended by Doug at Albumen Works.
CHEERS!
BOB

I hope that's true of my Centennial POP paper! Now that's slow!

I'm not a chemist and have learned that photographic chemistry is
exceedingly complex and advanced although one can get a rough idea of how
things work. I don't know for sure why some papers and films have longer
shelf life than others but in general the slower the emulsion the longer it
will last.
