Recently I started trying to size paper (BFK) at home with the chrome
alum/gelatine mixture outlined in the archives. My previous experience with
gum printing has been on formaldehyde hardened paper in a school setting.
After 4 exposures I noticed that the gum/pigment seemed to be sloughing off
in various areas of the image giving a slightly mottled look. Also, I
noticed that any manipulation with brushes was much more tedious. I sized
the paper twice, made sure the humidity wasn't too high when I sized it, and
did not print on it until 2 days later. Should I add more chrome alum to
the gelatine to try and get a harder surface or maybe size with 3 coatings?
Any suggestions on how I can improve my results would be greatly
appreciated.

Sincerely,
Barbara Dayton
