Just a comment on this. I tried to by some formaldehyde from a pharmacy
(just over the counter), and was refused, on the basis that it is aparently
used in the manufacture of Crack (and they smoke the stuff?). I persisted,
and they said that only with a registered business and a police check would
they be permited to sell me it. I said forget it, and bought some from a
friend who works at a University in town. Now legal, but I got it regardless.
The funny thing is, when I told the pharmacist I needed it for a photo
process, he said why bother, just get it done in the show in the mall. Fun
