Re: color of VanDyke/Longevity?
Sam,
The toner I use for VDB is the borax toner.
I always fix first and wash, then tone.
Sam you shouldn't go around calling people names like "chemist." ;-)
My degrees are in physics. As one of my former students said, " Chemistry is
one of the wet sciences. Physics is a dry science."
So there you go.
Bob
