Sil,
I have to disagree, I don't think any of the photographic chemicals in
common use would be adversely affected by glass, unless the glass
contained large amounts of metal (lead for example) that could react
with the chemistry. The only thing that I can think of, that might be
in a darkroom, and that could attack glass is Nitric Acid. The pH of
an alkaline would have to be pretty high to make it caustic to glass.
For years I've kept a saturated solution of Sodium Hydroxide in a
glass bottle without ill effect, so far as I can tell, to the bottle
or the NaOH. Can you point me to a reference that might provide more
info - I certainly make no claims to being a chemist?
