I agree with Judy and Kate; yes, I think heat is the problem. Having
never done much sizing, I don't have a lot of experience in this area,
but I do know that a couple of times when I got the gelatin too hot
(both times by microwaving it) the sizing failed and made speckles in
the prints. I'm not sure it matters what happens technically to the
gelatin; what is important is that overheating the gelatin seems to lead
to imperfect sizing, for whatever reason.
