Thanks, John. It looks a mess. Thinking I need to toss it.
I recently mixed-up a 5l batch of Xtol, from well-stored powder, using
"ZeroWater"
(counter-top DI cistern) as usual, in a clean stainless pot (that was washed in
the
dishwasher afterward). A few weeks later, I noted the appearance of sparkly
floaters
in the developer as seen through the brown glass bottles that have only ever
been
used to contain full-strength Xtol stock.
I noted this immediately before processing a roll of 100TMX, and, sure enough,
some of
those sparkly flakes were stuck to the emulsion, and Edwal cleaner wasn't
taking them off.
That's when I also noted floating junk in the remaining bottles.
I tossed the remaining stock, rinsed the bottles well, got a dedicated plastic
bucket
for mixing Xtol and made another batch. I note the first 100TMX I processed in
this
batch was a bit sharper than in the previous batch; more what I expect from
100TMX.
I can only speculate I contaminated the first batch, possibly with Jet Dry
residue on the
mixing pot, possibly with residue on the bottom of the funnel (since cleaned)
that I
used to fill the bottles, or ?
Anyway, if the develop makes you wonder if it's OK, it's probably not OK.

If it has been cold, maybe the components could not stay in solution. Sometimes gentle warming can help crystals go back into
solution.
However, if the color has changed, my guess is that some reaction has taken place and that would not be reversible. When
"Kodak" changed from the old water-free formulation to something more conventional, there was discussion about how long it
would last. My guess is that it will still work but maybe a bit weaker.
