Well, Garet, I have accused others of the "seems-logical-disease" in gum,
that is, making a supposition & then putting it into print before testing,
whereupon it perpetuates error through the ages -- so it is with some
misgivings that I say, I can't figure out how you can size paper with
gelatin that's liquid at room temperature. You count on hardening it
enough with glyoxal for it to stay on the paper? Doesn't seem likely from
here, what with global warming & all. But we wait on tenterhooks,
Judy
