Sorrry, I didn't make it clear. The gum print had been in the water at least
once and didn't develop out as I had wanted. I then took the blade to it
after the print had dried. I belive the lang time in the water attempting to
get it to develop would have also cleared it fairly well.
I also remember having some success using glass beads to develop prints. I
ended up with some tiny glass beads, I think 5 mill or something like that.
They were used in signs to make them reflective. Like paint the word stop
with white paint, cover wih glue,and sprinkle on the beads to get a
reflective stop sign. Used for stripes down the road as well. The beads are
relatively light and smooth. Gently pour on a table spoon or so of them onto
a print in the water and let them slide over the print as it develops. Iused
a substrate so it was easy to transfet to a new tray and recover the beads
that eventually go under the print. I guess it is a variation on the boxwood
sawdust thing.
Btw I think Dupont made the beads. I still have a bottle in the lab, and
if interested, I can get the data off the bottle.
