Candace said her gelatin came out of the microwave steaming. Whether it
was all steaming or only parts of it were steaming isn't the point.
Also, what gelatin does in the making of silver-gelatin emulsion isn't the
point... as we know from past discussions, even two processes much more
closely related than SG and gum, that is, carbon printing and gum, react
differently.

Again, heating something to "the desired temperature" is more easily done
in an open pot, with frequent stirring, than in a microwave. As for
gelatin *theory,* cited somewhere in this discussion, beside the fact that
gelatin theory is not yet handed down on tablets from Mount Sinai,in fact
still not set in concrete, I trust my observation more. Which is, after
all, how we know that the bumblebee can fly -- and that scalding
can cause speckles on a gelatin-sized gum print. Even brief scalding.
