Marilee -

Your carpenter friend is making too much of this. It is true that when you
have any kind of powerful exhaust fan operating, in order for it to be
effective you must also have some way for air to enter the building. In my
experience few ceramics studios are so tight that this is a problem - natural
air leaks around the doors, windows, etc. take care of it. Special
considerations - if you have a gas kiln or gas water heater operating in the
place, then you want to make very sure that you open a door or window when you
are running your exhaust fan. Also, if your studio is sealed VERY tight, then
the exhaust fan can actually suck a very slight vacuum, and will make a lot of
noise without moving much air, which is very dangerous if you THINK that it is
exhausting toxic fumes and dust. If your studio isn't sealed super tight, and
if you do not have any gas appliances within the studio, then you don't need to
worry about it. But if in doubt, open a door or window a little, even if it
means turning the heat up a bit in the winter when you are spraying.

I explored the idea of spray glazing and using an exhaust hood/fan/booth
arrangement but also considered it a concern simply to exhaust it
outside. Unless it was raining, the exhausted spray would be drifting
around outside (much like second hand smoke), and unfortunately, where
our studio is, there are plenty of people in the vicinity. The design of
a 'water' curtain was appealing, or some kind of filter/scrubber system
that would take the glaze particles out of the air would be more
desireable.
I'm wondering if there is anyone out there using this sort of spray booth
system? The simpler the better, but a small investment may be worthwhile
to ensure safety...

thanks Don Jung in Vancouver Canada...feeling the little earth tremor
