Description
Odourless thiourea toner for indirect sulphur toning.
Due to the variable mixability of toner and activator and varying degrees of bleaching, shades from light yellow to golden ochre to reddish brown can be achieved.
The prints must be completely washed before bleaching!
The bleaching times depend on the paper used, the desired image tone and the dilution of the bleaching agent.
If bleaching is not to be carried out completely in order to maintain the depth of the shadows, dilute at least 1+20 in order to be able to judge the progress of the bleaching. The bleaching time is then between 20 seconds and three to four minutes. Diluted bleaching agents (1+30 or more) must be washed out of the carrier and gelatine much faster than strong bleaching agents (1+10). Before toning, water must be added until the yellow colour disappears completely!
The bleach solutions have an almost unlimited shelf life.
The toner can be refreshed with concentrate when the effect wears off.
The toning of the bleached areas is complete after 20 to 30 seconds.
Partial applications are possible, the concentrates can be kept for years even after opening.
