RUBY.
For a good color the feathers must be white, naturally or bleached; scour and rinse them well. Add to two gallons of water one and one-half pounds good cudbear, stir well, enter the feathers and work them, while slowly heating, as long as the hands can stand it. Then lay them down until colored to shade, lift, rinse well, starch and dry.
SALMON.
I. Salmon or "flesh" may be dyed upon bleached naturally gray feathers, in which case the creamy tint of the feathers must be taken into consideration and can be utilized for certain broken tones of the color. Have the feathers well washed in soap or soda, and rinsed perfectly clean. For dyeing prepare a bath as for rose, preferably with ponceau B. R., or utilize an old bath for rose, according to its strength and the shade to be produced, and add in either case a suitable, small quantity of filtered decoction of turmeric. Proceed as stated for dyeing rose, with the difference only, that the acid may be added to the dyebath at once, if the bath is made fresh. Particularly fine shades are obtained with rhodamine and turmeric, in a bath slightly acidulated with acetic acid, upon bleached grays.
II. Prepare a bath as for rose, with some solution of eosine, a little quinoline yellow, according to tone, and a little acetic acid, just enough to give the bath a slightly sour taste. Enter the well cleaned, or bleached feathers after rinsing, at hand heat and agitate them until the bath is well exhausted, or a level color, according to sample, obtained, rinse lightly, starch and dry.
AMARANTH.
After scouring and rinsing, prepare a bath with one and one-half ounces alum per gallon of water, at 75-80° F., and lay the feathers down in it over night. On the next morning rinse them in cold water; then dye them at hand-heat to nearly boiling heat in a strained decoction of Brazil wood (or camwood, hypernic, etc.) until the required shade is obtained, and rinse in warm water to which some tartar has been added; starch and dry.
BRONZE.
For this color naturally gray feathers may be used if a deep shade is to be dyed; for light shades they ought to be bleached. Scour and rinse the feathers well; then prepare a bath with five per cent., of the weight of feathers, bisulphate of soda, to which add azo orange, acid violet and extract of archil. Dissolve the dyestuffs, each separately in water, filter, add the clear solutions gradually in small quantities until the shade is nearly reached, then, in order to correct, by drops, until the exact depth and tone are obtained. Enter the feathers and dye to shade at 170° F. Instead of acid violet indigo carmine may be used; in this case, however, as the dyestuff runs up slowly and difficultly, work at 170° F., for twenty to thirty minutes, then raise the temperature slowly to near the boiling point and continue at that temperature, without actual boiling, until the required color is obtained. Then rinse, squeeze, starch and dry.
Bronze is also produced like drab, that is, with azo orange, acid violet and fuchsine S., but with greater quantities of dyestuff. Bronze is also obtained with the recipe for any dark brown, by making the yellow in it predominant; particularly good bronzes are in this manner obtained from dark chestnut brown.
