Do they work with pyro? The Jobo is miserable with pyro do to the "slosh
factor" causing oxidation.
Has anyone tried doping the pyro with ascorbic acid? This might make a sort
of Xtol-pyro blend and reduce the oxidizing effect.
Any "real" chemists out there care to comment. Sil? Schramm? I'd like to
give this a shot if sounds as if it might work.
