RE: formula needed: Gum Arabic from powder

Thanks Chris,

This same method (1:2) is about all I could pry out of the Graphic
Chemical people... very nice, but a bit secretive expecially since
they sold me the stuff. What preservative would work well? I have
ascorbic acid on hand.

For me, Thanksgiving is a mixed blessing -- lots of work getting the
new(ish) house ready for the first famiy gathering. I know my students
are joyous... they were giggling in the computer room all day.

P.S. Snow is predicted for tomorrow, don't ya miss it?

-Darryl

Darryl,
Forget the baume. I mix it 1 gum (weight) + 2 water (volume). I
think the
usual is 1 gum +3 water but this is a bit liquidy for me, and I
noticed that
a lot of the original practitioners used the thicker gum--even thicker
than
this. It's nice and juicy when it brushes on.
Pretend you're mixing flour and water for gravy--a little water at a
time,
or blend the sucker up in your blender or food processor.
You can use it right away, no need to wait. One more myth.
OHH, add a bit of preservative or it stinks baaaaad.
Chris (who is thrilled to be on Thanksgiving break)
