[pure-silver] Re: AZO and Benzotriazole for anti-fogging

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.
