FormulasProducing brilliant blue tones, this formula is suitable for use with Cykora, Brovira and Indiatone Papers.

 

Hot Water (125F or 52C) 500 ml
Ferric Ammonium Citrate 8 g
Ferricyanide 8 g
Acetic Acid (28%) 265 ml
Water to make 1 L

 

Solution should be prepared with distilled water if possible. If enameled iron trays are used, no chips or cracks in the enamel should be present or spots and streaks may appear in the print.

 

Prints for blue toning should be fixed in plain, non-hardening hypo bath (which should be kept at a temperature of 68F or under to avoid undue swelling). When prints have been fully toned in the above solution, they will be greenish in appearance, but will be easily washed out to a clear blue color when placed in running water.

 

The depth of the blue toning will vary somewhat with the quality of prints toned in it, light-toned prints generally toning to lighter blues. Some intensification of the print usually occurs in toning; consequently, prints should be slightly lighter than the density desired in the final toned print.

 

Wash water should be acidified slightly with acetic acid since the blue tone is quite soluble in alkaline solutions and is considerably weakened wieh wash water is alkaline. Pleasing variations in the tone can be obtained by bathing the washed prints in a 1/2% solution (5 grams per liter) of borax which produces softer, blue-gray tones, the extent depending on the length of treatment.

FormulasThis formula gives a range of red tones to sepia-toned prints, the brilliance of the tone depending on the paper used. Brilliant chalk-red tones are produced on Cykon and India tone, while with Cykora darker shades are formed. If desired, deep blue tones may also be obtaned with this formula by using black-and-white prints instead of prints that have first been sepia-toned. Unusual effects of mixed tones of blue-black shadoes and soft reddish high-lights can be produced by using prints which have been partially toned in a hypo alum sepia toner.

 

Hot Water (125F or 52C) 750 ml
Ammonium Sulfocyanate 105 g
Gold Chloride, 1% solution ** 60 ml
Water to make 1 L

 

For Red Tones: Prints must first be bleached and toned by sulfide redevelopment method (Ansco 221). After washing, place prints in above solution until toning is complete (requires 15-45 minutes). For redder tone, one-half the specified amount of sulfocyanate may be used.

 

For Deep Blue Tones: Omit sepia tonight operation and place well-washed black-and-white prints directly in above toning solution.

 

For Mixed Tones: Prints should be incompletely toned in a hypo alum toner, such as Ansco 222, and washeed before treatment in above solution.

 

Ammonium sulfocyanate may be substituted by sodium sulfocyanate – 110 g or by Potassium sulfocyanate 135 g.

 

**The contents of a 15-grain bottle of Ansco Gold Chloride dissolved in 3 1/2 ounces of water will give a 1% solution.

FormulasWith this toner it is possible to obtain a variety of pleasing brown tones by varying the time of toning. Prints may be removed from teh bath when the desired color is reached. This formula is suitable for use with Cykora, Indiatone, Cykon and Convira.

 

Solution 1

Hot Water (125F or 52C) 4 L
Sodium Thiosulfate 960 g
Ammonium Persulfate 120 g

 

Dissolve the hypo completely before adding the persulfate. Stir vigorously while adding the persulfate. If the bath does not turn milky, increase teh temperature until it does.

 

Prepare following solution and add it (including precipitate) slowly to the hypo-persulfate solution while stirring the latter rapidly. Bath must be cool when these solutions are added together.

 

Cold water 64 ml
Silver Nitrate 5.2 g
Sodium Chloride 5.2 g

 

NOTE: The silver nitrate should be dissolved completely before adding sodium chloride.

 

Solution 2

Water 250 ml
Gold Chloride 1 g

 

For use, add 4 ounces (125 ml) of Solution 2 slowly to Solution 1 while stirring the latter rapidly. The bath should not be used until after it has become cold and has formed a sediment. Then pour off the clear liquid for use.

 

Pour the clear solution into a tray standing in a water bath and heat to 110F (43C). The temperature, when toning, should be between 100 and 110F (38 to 43C). Dry prints should be soaked throughly in water before toning.

 

Keep at hand an untoned black and white print for comparison during toning. Prints should be separated at all times to insure even toning.

 

When the desired tone is obtained, rinse the prints in cold water.

 

After all prints have been toned, return them to the fixing bath for five minutes, then wash for one hour in running water.

 

The bath should be revived by the addition of further quantities of the gold Solution 2. The quantity to be added will depend upon the number of prints toned and the time of toning. For example, when toning to a warm brown, add 1 dram (4 ml) of solution after each fifty 8×10 prints, or their equivalent, have been toned. Fresh solution may be added from time to time to keep the bath up to the proper volume.

Add Solution 2 to Solution 1. Then add Solution 3 to the mixture. Finally add 105 grams (3 1/2 oz.) of Potassium Alum to this solution and heat the entire bath to the boiling point or until sulfurization takes place (indicated by a milky appearance of the solution). Tone prints 20 to 60 minutes in this bath at 110-125 F (43-52C). Agitate prints occasionally until toning is complete. Care should be taken to see that the blacks are fully converted before removing the prints from the toning bath, unless double tones are desired.
