Sepia toners formulas

Formulas Toners Ansco 221 Sepia Toner). In some formulas, a copper bleach may be used, but this should not be confused with direct copper toners (see Direct Toners, above). 

However, by using a single-solution, sulfur-reacting toner such as Kodak T-la Hypo-Alum Sepia Toner or Kodak T-8 Polysulfide Toner (Formulas Toners Brown Toners) it is possible to convert the entire print at once. When this is done, the print cannot degenerate any further and instead of a ruined print the result is an archival print. 

This formula is similar to Ansco 221 Sepia Toner, without the rotten egg smell associated with sulfide toners. 

The 6-T system consists of three separate bleaches, three separate toners, a sodium chloride solution, plus a gold-tone modifier. By mixing and matching the various bleaches and toners, and throwing in the chloride bath and/or the modifier, a large variety of tones can be achieved from purplish-brown to a bright sunlit sepia. This system works best with old-style soft emulsion papers. (Formulas Toners DuPont 6-TToning System)...
