Usable age of Metol

[Jim Chinn]

I was at a photographer's studio yesterday because he had run an ad in the paper to sell some MF gear with a move to digital. They also had sitting on the shelf 2 16oz plastic containers of Kodak Metol (direct from Kodak) and I can't find an expiration date. The gentleman told me another photographer who worked for him bought it abut 3 years ago. He said I could have it for free.

I was wondering if there is a time at which metol would lose its potency? Neither container has been opened, both still have seals intact. I know I could mix up a batch of home brew dektol and try it, but i hate to waste any other chemicals if the metol would be "expired".

Any way to test it?

I'm not a specialist, but I have a pound of Metol I've been spooning for 20 years. I think if it doesn't turn brown or get speckly, then it's okay. Give it a try.

I had some for about 10 or 12 years. Worked fine.

Likewise-powder chemicals last for years if stored in a reasonably cool room.

I also have some for 15 years. As said before, store it properly.

Since Metol is the most expensive of all the bulk chemicals used when mixing Dektol, give it a try. If it doesn't work you won't be out much.
I'll bet it will still be good
