380. Another Gold Bath

Another Gold Bath. For Black and White Tones.

Water..............................................

64 ozs.

Aristo Gold, No. 2...................................

3 drs.

Salt.................................

15 grs.

Acetate of Soda (dry)...................................

oz.

Also a piece of collodio carbon, cabinet size, that has been over-printed, to ripen the bath. Make up bath 12 hours, or more, before using.

381. When ready to tone, add enough alkali to keep the white drapery from bleaching, while the shadows tone to a deep chocolate or purple.

382. Alkali.

Borax (crystals).................................

... 1 oz.

Water (boiling hot)..........................................

13 ozs.

383. Note. (a) In washing collodio carbon paper, plenty of water should be used in the trays. In the winter the chill should be taken off the water. Baths of good depth should always be used. Insufficient washing gives flat, muddy prints.

384. Note. (b) Prints should tone in gold bath to thoroughly clear the whites, and should not tone too fast, six to eight minutes being fast enough, as too fast toning gives flat prints. Too much alkali in the gold bath gives muddy prints and yellow whites; too little, gives pink whites and bleached prints. Taking prints too warm in color from gold bath gives olive tones when they are dry. Toning too far produces blue blacks. A ripened gold bath will always give better results than a fresh one. Do not use an old gold bath.

385. Note. (c) Instead of alum, some prefer salt as a short-stop in the second water after the gold bath; about two ounces of salt to the gallon of water. Another good short-stop is water made slightly acid with acetic acid.

386. Note. (d) If prints are not thoroughly washed between gold and platinum baths and platinum and hypo baths, muddy whites will result.

387. Note. (e) If prints show blue in platinum bath, and have not been toned too far in the gold bath, reduce the speed of platinum by adding water, and warm the bath slightly. If they show too much olive strengthen the platinum bath.

388. Note. (f) Should the whites show bleaching, or cutting out, in the hypo bath, add enough saturated solution of borax to turn red litmus paper blue in one minute.

389. Note. (g) Prints on collodio carbon paper will dry a shade darker in tone. They should show a slight trace of olive in the wash water if black tones are desired when dry.

390. Note. (h) Dry prints can be straightened by dampening slightly on the back with a sponge and then subjecting them to pressure until dry, when they can be trimmed and mounted.

391. Note. (i) If vignetted prints show yellow around edge of vignette, the bath is too alkaline. Tone the vignetted prints first, adding more alkali for the plain prints.
