Scott,
My gum has frozen dozens of times with no effect. There is a lot of folklore
that may have scientific basis but is of no reasonalbe effect. I have used
the same Ammonium Dichromate crystals since the sixties with no
deterioration evedent. I only recently finished off a bottle of am-dicromate
solution that was stored in a clear bottle for ten years or so. Making a new
solution showed no change in print sensitivity. But the books warn you to
keep the solution in brown bottles and caution about it going "bad". I love
the way Americans think of things as "good " and "bad". We must watch out
for bad soutions. Lately there is much talk here (Bloomington IN) about
"BAD" trees. A whole park was bulldozed so they could start over with "GOOD"
trees. Enjoy your gum. Not to worry!

Subject: Frozen Gum Arabic
Hi all,
After years of deliberating, I finally decided to take the plunge and try
gum printing and gum-overs.
Does freezing gum arabic have any undesirable effects?
I just received shipment via UPS ground and it arrived frozen solid as a
block of ice. It must have been that way for about a week since it went from
the west coast to the east coast. After thawing, it seems ok in texture and
consistency from what I can remember; but I am concerned whether it freezing
will cause problems with gum printing or gum-overs.
Cheers,
Scott Wainer
