FORMULARY NELSON GOLD TONER is similar to Kodak T-21 and is unmatched in its versatility.Tones range from just a hint of warmth to rich sepia browns. Toning can be stopped at any time between 5 and 20 minutes. Final images are permanent and are formed by a combination of silver sulfide and gold.

The toner is relatively inexpensive per print.One liter of solution is used to tone about 300 to 400 8x10 prints (with replenishment), depending upon tones desired. The satisfying results of this toner have made it a popular toner over the years.The chemicals in this kit are used to prepare a working solution, and the kit contains sufficient gold chloride for a replenisher solution.
