Re: [pure-silver] citric acid??
Agree,
Stop bath has always been a pne shot for me, with citric aid
is easy enough to use 1 tablespoon per liter, and dump at
the end of the session
Bromocresol purple! that was it! Bromocresol green changes
around 4.0 so is too early I guess
FWIW Ilford stop bath is citric acid based. The only
problem with citric is that its a sequestering agent for
aluminum so is not compatible with hardening fixing baths
that use alum although many people use it anyway.
