Odourless thiourea toner for indirect sulphur toning
You can
alter the ratio between toner and activator. By doing so and by bleaching
to varying degrees, it is possible to achieve image tones ranging
from bright yellow via gold-ochre to red-brown.
It is important
to thoroughly rinse the print before you start bleaching!
How
long you have to bleach depends on the paper you use, the image tone
desired and the dilution of the bleach bath.
If you don’t
want to bleach completely to retain the deepness of the shadows,
you have to dilute to at least 1+20 to allow control of the bleaching
process. This should result in bleaching times of between 20 seconds
and 3-4 minutes. Before toning you have to rinse the print until
the yellow cast has completely vanished! Highly diluted bleacher
(1+30 and higher) will be removed a lot faster out of carrier and
gelatine than strong bleacher solutions (1+10).
The bleach
stock has an almost unlimited shelf life.
If the toner starts
getting weaker, you can replenish with stock solution.
Toning
of the bleached areas is completed after 20 to 30 seconds.
It
is possible to use only parts of all stock solutions. Even after
opening they are good for years.
