Some times ago I bought a bottle of Kodak HC-110, CAT 5010541, expiration 2023-02. In october 2023 I mixed a stock solution with demineralized water and used it without issues. Since then, the stock solution bottle has been sitting 2/3 empty on a shelf.
According to the datasheet, the storage life of a half-filled bottle is no more than 2 months. I was about to throw away the remaining solution but ultimately decided to check with a clip test and the piece of film quickly turned black.
As I wanted to give HC-110 and fomapan 100 a try and had an exposed roll of not so important pictures taken in the neighbourhood, I developed the roll with this one year old solution : 6min at 20°c in dilution B, 30s initial agitation with the stick, 5s agitation every 30s still with the stick (6 half-turns).
It did developed the film and I was able to make a couple of prints, see attached. print of the bridge was at 60M on my jobo C660, 30M for the denser frame of the bycicle path. Paper is foma fomaspeed variant 312 17.8x24cm (7x9.5 inch).
