Hello All,
Can the "constant agitation" be the keywords? I can imagine that a
periodic "some" inversions in 30sec-1min-2min-etc. is far enough from
constant agitation, so Rodinal die later. A friend of mine made an
experiment with a third of a roll of T-Max in Rodinal 1+250 (2ml Rodinal
in 500ml water), 90min at 24 °C (75 deg F.) Agitation was once in every
min for the first ten minutes, then 30sec in every 5 mins. The result
was OK, so it seems to me that if the agitation is not continuous,
Rodinal doesn't die so soon.
Regards,
Chris

The German chemist Franz S. Borgerding published his experiment which
consisted in measuring the potential of Rodinal 1+50 at 20°C with
constant agitation. It fell under 700 mV after 17 minutes vs. normal
hydrogene. That means that the developer does not work no longer.
