They've already done it with acetone (or at least the stuff that isn't
adulterated with perfume, vitamin XYZ and whatnot). Last time I tried to buy
straight acetone, I ended up explaining exactly why I wanted it (removing
toner and photoresist from PCBs, and stripping enamel paint). I still ended up
leaving empty-handed ("you need Government authorisation to buy that, have you
tried nail varnish remover?"). Even sodium carbonate (used to neutralise FeCl
etchant) is a pig to get around here.

Some days I think the Government are doing all they can to stifle innovation
in this country. If they keep going the way they are, we're going to have a
nation with no scientists ("too dangerous"), no investment from sci-tech
companies ("ooo, their government don't like our kind, let's open a lab in
Berlin instead of London") and an economy based on selling houses and land to
developers for the highest profit...
