Hello Richard,
What I use is a little bite different but it is supposed
to react more
or less like the old polytoner. I use it very diluted.
Viradon 1ml
Sélénium Maco 2ml
Sodium carbonate 10% solution 35ml
Water 1000ml
I put the print in the solution for 5 to 10 sec and then
run hot water
at 45°C on it for 2 to 3mn and then in 10% sultite solution
for 2 mn.
I use this mainly with Bergger CV CB a warm tone paper
and I get very
nice cooler slightly blue blacks and subtle slightly
yellowish hightlight. I
did not get colored borders as mentionned earlier with very
diluted
polysulphure toners
Daniel
I will post the version of this toner given in a Kodak
publication because it is closer to what you are doing. Of
course it uses Kodak toners. There may be differences in
the toners. I don't know what is in the Maco toner, there
are several variations of Selenium toners, some of which
have some sulfide in them. Viradon does not list Sodium
Carbonate as does KBT, this is on the label and MSDS but who
knows what is actually in it.
These two variations of the combination formula come from
a Kodak booklet titled _Professional Printing_ first 1953
edition, included in the _Kodak Professional Handbook_. Here
are the formulas for reference. I have not tried either of
these.
Hue No.1
Kodak Rapid Selenium Toner 17.0 ml
Kodak Brown Toner 75.0 ml
Kodalk 30.0 grams
Water to make 1.0 liter
Replenish with KRST diluted 1:5, add 30 ml for per 10 8x10
prints per liter.
Use full strength. Tone for about 3 minutes at 70F
Hue No.2
Kodak Rapid Selenium Toner 2.0 ml
Kodak Brown Toner 100.0 ml
Kodalk 8.0 grams
Water to make 1.0 liter
Tone prints for 7 minutes at 70F
Replenish using KRST diluted 1:20, add 30ml for each 10 8x10
prints toned per liter.
The two tones are described as: No.1 a "rich, red-brown" and
No.2, a "warm brown".
The instructions state that No.2 tends to reduce the
print slightly so prints to be toned should be slightly
darker than desired.
I did note any tendency to bleach with the original
formula.
The text states that the Selenium toner is carried off
with the prints so it must be replenished with KRST as
specified.
Since posting I have also tested the original combination
formula on prints made on Freestyle Arista II, which I
believe to be Kentmere paper. It toned very quickly to a
purplish brown. Complete toning seems to occur within 2
minutes at room temperature. This paper tones is neutral to
slightly cold when developed in Agfa Neutol Plus. KRST 1:9
turns it a slightly purplish color with some intensification
(about 5 minutes). In Kodak Brown toner it turns a slightly
reddish brown, not really sepia, but a much stronger color
than in Selenium. Toned for about 5 minutes at 90F. In the
combination toner the paper becomes a cool sepia, strongly
colored. Toned for 2 minutes at 75F. There appears to be a
very slight toning or staining of the highlights with KBT
and the combination toner but these are bled edge prints so
there is no clear unexposed area to compare. The difference
is apparent only on direct comparison to the white area of
an untoned print on the same paper.
