I've never used the Ware formula, and know I shouldn't accept hearsay...
but many users do agree that double coating is the equivalent, in D-max if
not in scale. Though just to complicate matters... on some papers double
coating wipes emulsion off instead of adding it. That's generally on a
slick, hard paper, which won't absorb any more. You've got to test. (Tho
the Ware formula is, I understand, VERY finicky about paper, so it could
be, so to speak, a wash.)

Of course I never boast, but I cannot tell a lie: I got an offlist e-mail
said you'd made a big mistake, because, "I keep WJPFP in my office with

I keep mine in what used to be a living room.
As for toning, I've been doing a lot of (too many) tests (one test is like
one potato chip) and found out some things strange and stranger. The
toning, even with just tannic & sodium carb, has infinite variations...
and complex variables, missed by many/most books in print (except I think
James's TBOAPP). Gorgeous color, or so it seems small. The old books (19th
century) either go overboard with all kinds of toners or dismiss
possibility entirely. But, probably, their chemicals were erratic, and
their instruments imprecise. I think the variables can be controlled.
Probably. The archivality is good as far as I know... Or let's say, I
never saw strange white streak in a toned cyano like the one appeared on
that weird kalli.
