Umm... My emulsions also don't sink in the paper until they dry.

I would soak a small strip of sized but uncoated paper in water of
highest temperature you ever use, and try to scratch the paper surface
with fingernail. If gel's still firmly attached and not swollen too
much, it's well hardened!
(You can't tell hardening of gelatin when it's dry.)
I'll check out the website!
