Well, I got both the ferric and paper from Chris. I'm assuming that the
paper she's using now is different from the paper she sold me back in May,
but the "old ferric" may very well be from the same batch the I bought
from her. If that's the case, we could possibly rule out the ferric
(although it did seem to make a difference)

If I'm in a hurry, I tend to skip that step. The only reason I do it in
the first place is because I have a rather crappy contact frame and am too
cheap to buy a nice one. So it seems that the heat doesn't play a huge
role, but I wouldn't be surprised if it did.

All paper buckles to some degree when wet. I'd like to clarify that I
expose my paper almost immediately after coating (here it takes about a
minute to become dry to the touch), so the paper still buckles a bit,
especially in my frame (it cost me roughly $10 to build...and I was in a
hurry). A nicer frame most likely wouldn't need the pressing step.

I don't know for sure, but I would guess the humidity between her house
and mine are roughly the same. I don't have any means of testing this,
however.
