One part of Tetenal CN-2 comes in an honest-to-goodness brown GLASS bottle, apparently 250ml . I'm saving these puppies.
I've found that I can develop two (2) rolls of 120 at a time in 250 ml of chemicals - although JOBO says 270 ml - with *no* problems. Just enough for one 1500 series tank load .. and 1 liter of chemicals will be sufficient for eight rolls of film. So now, mix one liter, decant into (4) 250 ml bottles, and use one bottle for each load. Cover each with a shot of butane from my Bernz-O-Matic torch and Iamb done.
