You should specify that this applies to Iron-blue toning,
not to Gold toning. Gold does not produce the brilliant blue
of Iron but is very permanent. Iron toning converts the
silver to a form similar to cyanotype. It is affected by
alkaline solutions and too much light but will often
regenerate in the dark. In general, ferricyanide-metal
toners, like Iron and Copper toners, are less permanent than
the raw Silver image.
