For those of us who don't have a Chemistry department at quite that level
of beck-and-call, not to mention having students who could break glass at
50 paces (and the occasional slip-up of our own)is there any particular
reason for using a glass rather than an acrylic rod?

If your gelatine is worm & liquid you can't/don't need to brush it off,
any more than you can brush water off a wet paper.
However you could squeegee or roller water out of the paper & this is in
effect what the rodding does with gelatine -- whether it's necessary is
something I've always wondered about. My guess is that it doesn't hurt,
and makes you feel like you're doing something. I also suspect that
simply making a more dilute gelatine (say 3/4 strength, or 20g/litre) and
not squeegeeing could be as good. There is in any event no "best" for any
one feature as they all interlock and affect each other (paper, size,
pigment, emulsion, etc.)
