BLUE
TONERS

Commercially
made blue toners fall into two basic types; those based on ammonium ferric
citrate, and those that use a mix of other iron salts to achieve the same
effect. In all cases the same Prussian blue dye compound is formed, although
you may prefer the action of one make over another after testing different
types. If a particularly subtle blue is required, or archival aspects
are important, possibly look at gold toning (without initial sepia). Otherwise,
if you are mixing blue toner from recipe, the substitution of a mild acid
(such as tartaric acid) for hydrochloric acid may have the desired effect.
Alternatively, the new Speedibrews 'Porcelain' Blue toner provides another
option. Always try to use blue toners as fresh as possible - staining
of the highlights is the principal problem, and usually indicates stale
stock solutions or working solution on its last legs. The Prussian Blue
dye compound is soluble in alkaline solutions, which includes tap water,
and will tend to reduce on washing.
