With clue from Alain's forward of Bas's June 2 '96 posting I found the
following in my file:
On May 29, '96, under subject line "Buying Gum Arabic" Martin Becka wrote
(& I summarize):
LP Clerc says 2-3 g salicylic acid to 1000 cc mixed gum (500g gum, add
water to make 1000 cc)
H Schneeberger says 5 g salicylic to 1000 cc gum
Puyo says use fresh mixed gum
I [Martin] add 3 g salicylic acid to mix of 500g gum, water to make 1000
cc....
PS. Seems to me [Judy] the 50& solution makes a VERY thick gum, at least
with contemporary powdered gum arabic.....
Anyway, thanks to all.... More to follow on my search for the slowest gum
in the west....
