To tone a silver print means to change its color and give it more brilliancy and this is done by putting it in a chemical solution made of chloride of gold, or toning bath as it is called.

To fix a print means to treat it so that the light will no longer act upon it and this is done with a solution of hyphosulphite of soda or just hypo as it is called for short.

The easiest way to tone and fix your silver prints is to buy a bottle of solio toning solution44 which is

42 Solio paper is coated first with gelatin and then with silver. 48 Silver paper is coated first with albumen and then with silver. 44 It can be bought at any store where photographic materials a combined toning and fixing bath. Take the print from the frame and do not wash it but put it into a tray in which you have mixed 2 ounces of solio toning solution and 4 ounces of cold water.

When the print takes on the proper color put it into another tray containing a solution made of 1 ounce of salt and 32 ounces of water; let it stay in this bath for 5 minutes to stop the toning. Now put the print into another tray and wash it in 16 changes of water or in running water for an hour. If you make a half or a dozen prints at once you can tone and fix them at the same time.

Recipe for a Combined Toning and Fixing Solution

To make a combined toning and fixing bath mix up two solutions, called stock solutions, as follows:

Stock Solution A
