Is the toning being done with sulfuric acid?

Hi Don, have you actually did that? I'm asking because my results with
Argyrotype and LiPd toner were really / awfully poor... If you did that I
would like to learn the details. (Such as exact toner formulation.) What can
you say about why the toner behaves differently with Argyrotype? For
instance, gold-thiourea toner behaves pretty much similarly with both
Vandyke and Argyrotype. (I'm not talking about final color - which is still
similar, but I'm rather talking about toning strength / success of the
operation...)

BTW, B&S Li2PdCl4 solution's strenght is something like 24-25% IIRC. (0.93M
exactly; that's what I was using for mixing my AFO sensitizer - according to
their recommendation.)

Regards,
Loris.

Chris,

One can substitute LiPd for Sodium Palladium, as sold from B&S which I think
is a 15% solution, in toning formulas such as the one listed in Sandy King's
article on Kallitype printing found on Ed Buffalo's Unblinking Eye website.
The effect will be similar or close to what one sees when using sodium
palladium.
