Well... I'd be a little more suspect of the liquids... YET, I'd guess that unless they were exposed to the atmosphere, they are in good shape. I'd also not be surprised to hear that there was a slight loss in speed...

Over the last year and a half I've been using up chems that were given to me rather than tossed - they were all from teh late 80's mid 90's.. BUT - all in powder form. With one exception - a jug of Clayton print/film developer, which I have not used yet as I hate to have to retest everything after only one gallon... All the chemistry that I have made up from the powders is A-OK, with not so much as a hickup. Times for known film/dev used straight from The Mas Dev Chart have been ON enough for me to do a tweak here and there, and that's all.

NOW - it looks to me as though it's all color chems that you are talking about.. and THAT, my friend, I have no idea about.
