RE: Toning cyanotypes

I also would like the formula to tone Cyanotypes to brown tones.
Please be kind enough to post it to the list.
Or if anyone else has any Cyanotype toner formulas please post them.
Thus far my toning attempts have only included toning with Borax and Ammonia
(two separate toners not combined).

Thanks,

     I believe cyanotypes have a tonal range pretty close to a platinotype.
There are those who believe that they lack permanence, but that has not been
my experience. Most of the platinotypes I have seen have brown tones, but
the ones I make are black and white. It all depends on the developer you
use.
Assuming you instructor was referring to a brown and white platinum print,
it is possible to tone a cyanotype brown using tannic acid and sodium
carbonate. I don't have the formula at my fingertips but someone on the list
may supply it. If not send me an email and I will look it up and send it to
you.

     There is also a formula which will tone the cyanotypes so that they are
black and white. I tried it at one time but I didn't care for the results.
The toned images looked grey rather than black and lost considerable
contrast.

Best wishes,
