Old mix still works?

[estevam]

I have used a mix prepared one month ago, I developed 3 rolls of 24 exp 35mm Arista Premium. The first roll was developed while the mix was fresh, the second roll when it was 1 week old, both were OK. The last roll came out almost blank (yet I got a few usable imeges after scanning), even after increasing developing time.
It was Caffenol C-L with iodised salt.


Has anyone else used old mixed Caffenol? How did it go?

hi

i always use old caffenol, i hve never used the mixture you used but i add a teeny bit of stock ansco130 to my coffee soda vit c mixture.
as a matter of fact i removed about 1L of old 4month old caffenol that i put maybe 100 sheets/rolls through ... and put in another L of caffenol into
the seasoned mixture. i will be processing film with it in the next few days. never had trouble .... maybe yours died because it was not a lot of developer to start with?

good luck !

Yes, most likely I exhausted the developer. Thanks John!

Caffenol developers are pretty cheap, why not just mix what you need for that session and use it one shot.

hi darkroommike

i used to use it one shot but realized it was convenient to just re-use it. no other reasons ..
