The fuming boxes are being build for making daguerreotypes and they are
definitely made of wood. The fumes in question eat through plastic as with
time and metal is useless around these chemicals.
I am only going to use first iodine and a method called Becquerel. Later on
I will move to mercurial dag making and use mercury and bromine. Bromine
being the real scary one. I think in the bible is referred to as brimstone. As
it stands iodine is a powerful oxidizer and it will also eat through plastic
given time.
I have a fume box that I am finishing and a fume hood with a 6\" exhaust hole.
The ventilation inside the fume hood needs to be almost stand still, otherwise
will still move towards the user, and still with 100% speed towards the hood
exit measurable with a venometer.
The tricky thing is that the exhaust fan is best placed outside the house as
there is still some loss of fumes in the connecting areas. In other words, it
cannot be connected to the fume hood directly.
