I obtained a Ziatype kit from B&S, about 2 years ago. I contains 2
bottles of AFO, last month I tested the unopened bottle (stored in the
dark, at around 22 degC) against my " work bottle", couldn't see a
difference, but obviously the real test would be against a fresh
solution: I'll make one, one of these days...

Ps I tested the presence of FerrousOxalate with the PotFerriCN test:
nothing happened so the solution is supposingly still ok.
