I am wondering for how long did you tone them?

These look like untoned FerroBlend prints to me. This is how they come out of the process.

Thanks @koraks, @nmp, @NedL, @Graham06 and @Patrick Robert James.

@Graham06: Debanjan posts regularly his works in Gum Bichromate Photography FB group. But I've no idea if the gum prints from the two negatives can be found there. FB search is quite underwhelming unfortunately.

@Patrick Robert James: no toning here as rightly observed by @koraks.

Whoops! Sorry! I got these mixed up with copper toned cyanotypes in another thread! So much new stuff these days....

Things have been slow in this thread so here are a few salted-paper prints I made yesterday.

All are on 8x10 inch Hahnemühle Platinum Rag and the images are 6x7.5 inches or 6.5 inches square.

"The Back Door" (untoned)

The Back Door (gold/bicarbonate toned)

MacDowell Dam (gold/bicarbonate toned)

Bottles (gold/bicarbonate toned)

Nice Frank.

Thank you both for the kind words.

Yeah, wonderful prints and images., Frank. Interesting that the toned prints move almost to cyanotype blues (or is it that my eyes tricking me or may be digital duplication is doing the tricking.)

:Niranjan.

Im curious about the gold-citric acid and the gold bicarbonate toners. Whats the recipe for them? I would love to try one of them out on this print. Van Dyke on Legion Stonehenge.

Niranjan,

Thanks!

The gold/bicarbonate prints in hand are certainly a neutral, bordering on cool gray. I'm not sure I would go so far as to say they are blue though.

Gary,

I use one of the many variations of gold toner cited in Chris Anderson's salted-paper book.

The recipe is very simple 7 mL of 1% (w/v) gold chloride + 500 mL 1% (w/v) sodium bicarbonate. Mix together until the solution goes from yellowish to colorless. I use it for one printing session and then discard. Actually, I often make only 300 mL of toner which is the minimum I am comfortable with in a tray for 8x10 paper.

This toner is used PRE-fixing. Processing is 2x 5% (w/v) salt for 4 min each, 1x with water for 4 min and then toner. After the toner the processing is 1% sodium carbonate for 4 min, 2x fixer for 4 min each, water for 4 min and lastly hypo clear (10% sodium sulfite) for 4 min.

I took a quick look in Don Nelson's book on the iron-silver processes. Among the many variations of gold toners for Vandyke Brown that are listed he mentions exactly the same gold/bicarbonate recipe cited above as giving a deep chocolate brown on HPR. Do note that, as with salted-paper, all of the toning of Vandyke brown prints is done before fixing.

The incredible variety of colors resulting from the action of different gold toners on a Vandyke Brown print is quite amazing. It is well worth a look at Nelson's book just for this chapter alone.

P.S. I do not see a gold-citrate toner mentioned in either the salted paper book or the iron-silver processes book.
