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 donít 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.
