Terry King and I both worked a little on chrysotypes in the late 1980s,
and recently he has published some of his pictures by what I think he
calls the Chrysotype Rex process.

My approach was to use the same sensitiser for all the iron processes,
creating a solution of iron(III) oxalate from iron (III) nitrate and
potassium oxalate, usually with a small amount of free oxalic acid. The
exposed prints could then be treated with various solutions to give
kallitype, platinum etc prints. I wasn't impressed enough with the
results with gold solutions to publish these, but I did produce a couple
of chrysotypes.

I think there was a set of instructions for the Satista process
(silver/platinum) on the Bostick & Sullivan website that was the one
variety of this approach I thought of some interest, but I don't know if
it is still there. I don't know how much Terry has departed from our
approach then in his more recent work, but I suspect it is fairly
similar. Probably it would not take a great deal of experiment to
produce either chrysotypes or fast cyantoypes.

Regards,

Peter
