Photographers' Formulary GP-1 Toner for Black and White Prints, Makes 1Lt Solution

Formulary's Gold Protective Toner is similar to Kodak GP-1 and offers maximum protection with little or no change to print color. However, with some prints a slight shift towards blue-black may be noted. Prints treated with Gold Protective Toner are even more stable than those toned with selenium or sulfide. This toner can also be used to protect negatives. The chemicals in this kit are used to make a working solution, which has a capacity of about eight 8x10" prints per liter.
