DEAR TOM,
Kodak publication J-1 Photo Chemicals does show it on Page
41. In
an e-mail conversation a few days ago with Doug Corbin
formerly of Kodak he
still recommends it. I don't know if anyone has said
otherwise. Perhaps
Richard Knoppow can shed some light on this.
CHEERS!
BOB

toner as an
alternative to ST-1 test solution
Going through the pure-silver archives, I came across a
reference from
2007 by Richard Knoppow suggesting that at one time Kodak
recommended
using KRST diluted 1:9 as an alternative to the ST-1
solution (testing
for residual silver) but no longer do. Is there a reference
for this
information?
Tom Kershaw
Thanks, for this. I certainly have the publication but
I still have an enormous amount of stuff in storage and,
frankly, don't have the physical strength to search through
it. I this publication actually says that the stains match
the Kodak Hypo Estimator card, which is also used for the
residual silver test, better than the sulfide stains.
However, see my previous answer about why Kodak may no
longer recommend this test.
