I took tintypes #2 & #3 (the 4x5 split ones) and framed them into an 8x10 frame
and I was happy with the result, which looks a little more shinier than the images
shown.
I also noticed that spending 4 hrs on Sunday breathing fumes, including some
unavoidable residuals from potassium cyanide was not a good idea. I should
have used a chemical mask.My breathing has been shallow since but getting
better today. One cannot ever get too comfortable around chemicals.
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
enough 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.
These processes intrigue me, but the chemistry gives me pause. At University, many many years ago, I worked in a chem lab for a couple of years while at school, but we had all the safety gear when we worked with nasties. Be safe!

Brimstone is sulpher, not bromine.
My question is: what do you do with the waste chemicals when you are done with them?
Mercury has gotten into the food chain, and bromine is known to cause depletion of the ozone layer.
Words that concern me about iodine "sublimes slightly at room temperature" , that is exactly how the plates get fumed. Clearly it should never be heated but also a certain temperature is needed and if cold it helps placing the fuming box in sunlight. To help keep temperature I use a small blanket of thin teflon inside the pyrex container that holds it.
