Yes the green I'm refering to is a yellow-green; but it is definatly
green and not just yellow. The yellow is just yellow. Maybe the
Handbook should be corrected.
As to the emerald green K3[Fe(C2O4)3: I seem to recall useing some very
green liquid sensitizer before I started buying my sensitizer from B&S
in 1986. I got it from a Fred Foster, 77 Summit Rd., Prospect, CT
06712, 203-758-5165. He called it Ferric Oxalate and sold it by the
quart. I do remember it to be quite green. I do not know if this was
the K3[Fe(C2O4)3 you are asking about, but you may give Fred a call (I
have no idea if he is still there.) His solution worked fine. I
swiched to B&S because they offered a powder ryoung@chicoma.la.unm.edu (longer shelf life).
