Dana, tell your father when he calls he didn't answer my question and that
nobody is considering setting anything on fire in a classroom, least of
all ammonium dichromate. Also, that we Americans NEVER inhale.
As for the legend on the bottle, every one of us has a bottle of
dichromate on the shelf. In fact you can't subscribe to this list without
one. And every one of those bottles says things that are even worse than
his bottle, which is really just boiler plate, everyday blah blah, not
even as good as on my bottle of Light Impressions gum arabic (quoted here
last year) which when you get over your terror at the label you could
maybe make gum drops out of.
What I was asking, and still not getting an answer to, which I begin to
think means "no," was has anybody ever seen a bottle of dichromate
explode or catch fire WHEN IT WASN'T SUPPOSED TO?
And if no one has, Why not? Because everyone, including your space-cadet
students is so all-fired squeaky clean careful? or also because maybe the
risks have been laid on with a trowel. Not that I take back any of the
precautions I suggested, and I appreciate Dick's addition of apron, which
is of course essential for darkroom and studio: you take it off when you
leave, otherwise you carry chemicals around on your person all day.
But.... still asking.
