Thanks Terry -- good to know I don't have to dissolve the crystals. I'd never heard of anyone doing this before reading Pete's post.

Re. dead Rodinal, I am aware that some of the formulations from recent non-Agfa makers have had issues with early death. As a matter of std. practice I am now doing a clip test before submitting any roll to even slightly aged fixers and developers (Rodinal-type and all others) just to make sure they are still good. I will most certainly do this with my old APH-09, as I am not confident it will still be active.

So do I now Svend - especially since my Rodinal blank film shock. I do it with all film developers now, even fresh ones. It doesn't take long to do and it's well worth knowing in advance if the developer - of any age - is still any good.

It was the first time I tried to dissolve 'RODINAL' crystals BUT I have done it with Part A of a C41 process kit I got from 'CPAC Chemistry' some years ago as that is the Alkali and I was finding the dev was not active enough so I dissolved the crystals by Microwave gentle warming.

The microwave has many uses for which it was not originally intended. I give colour film developer a bit of microwave treatment to heat the working solution that I am going to store until I need it. Get it up to about 40-50c in 150cc bottles and then screw on the cap. As it cools it forms a partial vacuum. I have three bottles left from my last mix made 5 months ago and it is as good now as when it was prepared.
