I remember using water and alcohol to dissolve gum about 25 years ago...
based on something I had read. I was using gum and dichromate to make a
photo resist to etch a copper plate for a fired enamel inlay. I added some
pigment so I could see what the heck I was doing. I guess that was my first
gum print without knowing it. I wonder if the alcohol might also keep the
gum from "spoiling"?

This may be a case of parallel invention -- or more precisely
re-invention. It's not common, but does appear from time to time in the
old formulas -- a certain percentage of alcohol added to the mix. The next
time I come across one, I'll post it. But it remains in occasional use, or
was a few years ago, tho perhaps as a cure for a specific coating problem. >>
