HC110 - odd?!

Hi All,

I've got an almost-full bottle of HC110 that I bought a couple of years ago. I have only used a bit of it, and it is still pretty yellow.

Before I used it today when I noticed an amount of white crystals / sediment at the bottom of the bottle.

The film itself was probably underexposed, which was my fault... but, could the presence of the crystals mean that the HC110 has also gone off? I have seen little or no mention of this anywhere!

Thoughts gratefully received!!

I got those crystal in Rodinal after bottle is opened for couple of months, but all works as usual. My bottle of HC110 is opened more than a year ago - still 1/3 full. I just developed expired Tmax 100 in HC110 - all works ok. I don't think HC110 has gone off.

It's probably OK but why not do a test roll to be certain.

Trouble is that I did process a roll, hence the original question - the film was expired, but I have had success in other developers previously.

I've seen that Rodinal can acuqire crystals (some old R09 I have has this) but have never seen any mention of the same thing happening to HC110.

Might try again, but if it has to be thrown out, that's life!

It should be fine - it's just a sign that the concentrate is supersaturated.

If you decide to throw it out I'll take it.
