- Water twenty to thirty parts, chlorate of potassa one part, sal-ammoniac one part, chloride of copper one part, aniline hydrochloric acid one part, previously mixed together. It is essential that the preparation should be acid, and the more acid it is the more rapid will be the production of the blacks; if too much so, it may injure the fabric.
- Dissolve one pound of the brown in two gallons of spirit, specific gravity 8200; add a sufficient quantity to the dye bath, and immerse the fabric. Wool possesses a very strong affinity for this color, and no mordant is required.
Place the feathers from three to four hours in a tepid dilute solution of bichromate of potassa, to which, cautiously, some nitric acid has been added (a small quantity only). To remove a greenish hue induced by this solution, place them in a dilute solution of sulphuric acid, in water, whereby the feathers become perfectly white and bleached.
For one pound of silk, alum three ounces; dip, at hand-heat, one hour; take out, and drain, while making a new dye, by boiling ten minutes, cochineal three ounces, bruised gall-nuts two ounces, and cream of tartar half an ounce, in one pail of water; when a little cool, begin to dip, raising the heat to a boil, continuing to dip one hour; wash and dry.
Give the goods as much color from a solution of blue vitriol (two ouces to water one gallon) as it will take up in dipping fifteen minutes; then run it through lime-water; this will make a beautiful sky-blue of much durability; it has now to be run through a solution of prussiate of potash, one ounce to water one gallon.
First soak the bonnet in rather strong warm suds for fifteen minutes, to remove sizing or stiffening; then rinse in warm water, to get out the soap; now scald cudbear one ounce in sufficient water to cover the hat or bonnet; work the hat or bonnet in this dye, at 180° of heat, until you get a light-purple; now have a bucket of cold water, blued with the extract of indigo half an ounce, and work or stir the bonnet in this until the tint pleases; dry, then rinse out with cold water, and dry again in the shade. If you get the purple too deep in shade, the final slate will be too dark.
Cut some white curd soap in small pieces, pour boiling water on them, and add a little pearl ash. When the soap is quite dissolved and the mixture cool enough for the hand to bear, plunge the feathers into it, and draw them through the hand till the dirt appeal's squeezed out of them; pass them through a clean lather with some blue in it; then rinse them in cold water with blue, to give them a good color. Beat them against the hand, to shake off the water, and dry by shaking them near a fire. When perfectly dry, coil each fiber separately with a blunt knife or ivory folder.
