Also accordian bottles are not as good as they seem because supposedly bubbles get trapped in the pleats and cause oxidation. Xtol doesn't turn brown when it oxidizes so there is no warning when the developing components have oxidized. I know Xtol is wonderful stuff, but its just too darned fussy for me hearing all these failure reports. I'd much rather mix something from scratch than deal with little bottles etc. Just me of course. I know many people have made their peace with it.

I just used the same Xtol 1+1 from the same bottle couple weeks ago for the "United Walkway" pictures and they came out just fine. Both bottles are down to the bottom so this is the end of the initial mix. So 4+ liters are OK, but these last 500 ml.... >It's late on your end ... maybe you made a mistake? > >I've gone through countless 5 liter batches and of course I get >nervous when I hear this, but I am starting to think it is a myth and >that the failures are due to simple mistakes (I've made them and the >results look like Xtol failure, but it wasn't). The negs are practically clear. I just checked the canister and it is Delta 400. I checked the M7 and the meter reads good. I use a Jobo and I even checked the solution temp (20 degree C) Arggghhh >Daniel > > >On 6/13/06, Richard <richard-lists@imagecraft.com> wrote: >>I am on the end of my Xtol batch, this is the 3rd 5 liter batch I am using, >>I believe, and... >> >>you go it, the $#%$^ Xtol sudden failure.
