paper fog

I have some Forte WT paper laying around unrefrigerated for about 4-5
years, I understand Forte doesnt last too long. How should I test it,
or should I even bother?

You should test it, - can be a relatively simple method.

Take a single sheet develop it in developer
without exposing it, stop, and fix it if it looks grey(er) than the
white border of a print you made when the paper was fresh, its fogged.

Better test:

Place a piece in the fixer WITHOUT developing it, and run a pice
through the developer and fixer, then compare them.

Add maybe benzotriazole (liquid Orthozite)
to the developer to help cut through the fog.

The paper should still be usable unless trying
to exactly match a print before fogging.

For some reason I though fog would show up better if there was some
additional exposure to the test paper. At any rate, it seems to work
pretty good. Makes me wish I'd stuck it in the frig one of the 50 times
I've seen it laying there in the last few years, but I was under the
impression that Forte goes south pretty fast.

Refrigeration wouldn't have prevented fogging.
Fogging occurs due to two reasons: chemical and
radiation. Refrigeration may slow down chemical
fogging but I've had film that was frozen at
-20 that still fogged...

You mean you have not lined your refrigerator with 1 centimeter thick lead
sheets to reduce the incident radiation? ;-)

The high contrast end (3-4) quit on some Forte WT RC I have that's less than
8 years old. The low end (2-1) still works but it's basically been relegated
to contact sheet duty. The fiber paper from about the same period still
works great. I thought they were the same emulsion but one is somewhat
faster than the other (I forget which is which) so I guess not.

Guess I'm just an irradiated kind of guy :^)

I never really intend to store film that long
(10+ years), but I guess many do...
