The Foma Fomatoner Sepia 2 x 250 ml is a liquid concentrate, two-bath sulfide-based toner for resin-coated or fiber-base black and white photographs. It will give your black and whites a yellow-green to brown to violet-brown tone. Toning occurs at various temperatures and the length of time depends on the desired effect, but is generally from 1.0 to 5.0 min. One set is enough to tone about 54 sq ft (5 sq m) of paper, or about 100 8 x 10" (20.3 x 25.4 cm) prints. The Fomatoner is composed of 2 parts (bleaching solution A and toning solution B), each of which is diluted with water in a ratio of 1:9 to control image tone and toning speed. Water of low hardness, preferably distilled, is recommended. After being washed, photographs are first put into the bleaching bath, then washed again and placed in the toning bath. Following toning, photographs should be washed thoroughly again, preferably in running water.
