Hello,
I am about to purchase a kiln and have some queries regarding the
fumes/vapours given off during the firing process by the metal oxides in the
glass, glass stainers colours, silver stains and enamels and other processes
of firing etc.

Don't worry. I have seen a number of glass shops and they never bother
with ventilation unless they are commercial (and therefore subject to
the rather strict dutch laws.
