Exactly 3 years to the day before Sam Wang's latest message (Jun-10-1995),
he wrote to the list, "I use 2% dichromate (either ammonium or
potassium) for gum. . ." I was just beginning to think about trying
gum and being Scotch, using the least amount of chemical seemed the
way to go. I haven't compared using different dilutions and since I
print outside, times aren't very meaningful (3-10 minutes depending on
sun/clouds). I use about equal volume of gum and dichromate solution.
As Sam said in '95, using less dichromate means less gets put down the
drain and you're spending less. It works for me and I am happy with
the results I am getting.
