Fumes and ventilation
 

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.

My simplest ventilation option for withdrawing undesirbable vapours is
venting directly into the interior space beneath the eaves of the roof ,
which is well ventilated by a continual movement of fresh air through the
slates - BUT - will the constituents of any of the vapours damage the roof
timbers in any way?

Or, would a cooker hood with charcoal filter be a safe option for removing
these vapours and for recycling the air - the room is ventilated at all
times.

I am trying to avoid breaking through the roof or a long ducting job.

Thanks for any suggestions,
Bev

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.

PAAI, you give BAD advice.
If Ms. Robinson.. here is going to be striking color or annealing
metallics, she needs ventilation. The dust given off from the
degredation of the kiln is cause for ventilation enough.
There are so many reasons, i can't list.
Be safe!

On second thoughts you may be right. But what is 'ventilation'?
The heat of an oven is so high that you take every opportunity
to open windows and add ventilators.
For the small table where the colours are added, we have added
ventilation, but not for the oven itself; I assumed that she
talked about that situation.
