Tetenal RA4 life?

[hoffy]

OK, I know the proof is going to be in the tasting, but I thought I would ask for others experience.

I have an open 5L Tetenal RA4 kit in my cupboard. It was purchased 12 months ago. I mixed up 1 litre of working solution of all chems and used it over a couple of weekends before my Jobo broke. While I don't expect that the working solutions will be OK (there is still some in their respective bottles), I am wondering whether the concentrates would be OK.

Thoughts?

Cheers

Have a look at Ctein's book on printing, where there is specific discussions on room temperature RA-4, along with comments on the stability of Tentenal kits:

A pretty darn interesting read otherwise.

Cheers. I have that downloaded somewhere (other computer I think). I'll check it out

and the proof was indeed in the pudding - maybe I am easily pleased, but every thing seemed to work OK. I do have some issues, but that is possibly more to do with process then the chems

BTW, the tetenal suggest 24 weeks is the life span of the chems once opened.
