But there's a logical flaw in saying "I never saw it, so it doesn't exist".
Storage conditions -- temperature, humidity, presence of fungal spores -- will
have an influence. I have seen enough mouldy glass mounted slides to take this
issue seriously (I live in the sub-tropical zone). As to out-gassing, I would
keep an ear open to what the conservators say.
