FORMULARY POP COMBINED GOLD TONER-FIXER is simple and dependable. It contains sodium thiosulfate and gold chloride. By combining the toner and the fixer for printing-out-paper, considerable time is saved. The chemicals in the kit are used to make 1 liter of working solution, which has a capacity of about thirty 8x10 prints. Care must be taken to ensure that the prints are fixed. If the desired tone is reached quickly, prints must be fixed in a separate bath.
