Hi,
I do toning on B&W prints. Especially after lead bleached toned with thiourea, 
a thin white layer forms. Probably it is a compound of silver with 
ferricyanide, thiocyanate or similar or lead compounds of similar since bleach 
has lead. Any comment? I have tried to use acetic acid solution, but it did not 
help.

Regards,

Ibrahim Pamuk
