The following just came in to me from Joe Traynor:


Re: oxalic acid:   Under high heat oxalic acid turns to formic acid
(with the release of carbon monoxide - CO); so you may essentially be
treating with formic if you're using the evaporator.  I didn't
believe this at first but a beekeeper (smarter than me) sent me a
spec sheet on oxalic.  I ran it by a person with organic chem
background and he said "of course" - he knew the chemical formulas
for both - knock a C and on O off oxalic and you've got formic.  Both
are hazardous - formic probably more than oxalic.

    FWIW.
