Purple

To two pounds of chip logwood and half a pound of Brazil dust, add four gallons of water, and after putting in your veneers, boil them for at least three hours; then add six ounces of pearlash and two ounces of alum; let them boil for two or three hours every day, till the colour has struck through.

The Brazil dust only contributes to make the purple of a more red cast; you may therefore omit it, if you require a deep blush purple.

Orange

Let the veneers be dyed, by either of the methods given in page 54, of a fine deep yellow, and while they are still wet and saturated with the dye, transfer them to the bright red dye as in page 55, till the colour penetrates equally throughout.

Silver Grey

Expose to the weather in a cast-iron pot of six or eight gallons, old iron nails, hoops, etc. till covered with rust; add one gallon of vinegar, and two of water, boil all well for an hour; have your veneers ready, which must be air-wood (not too dry,) put them in the copper you use to dye black, and pour the iron liquor over them; add one pound of chip logwood, and two ounces of bruised nut-galls ; then boil up another pot of the iron liquor to supply the copper with, keeping the veneers covered, and boiling two hours a day, till of the required colour.

Liquid For Brightening And Setting Colours

To every pint of strong aqua-fortis, add one ounce of grain tin, and a piece of sal-ammoniac of the size of a walnut; set it by to dissolve, shake the bottle round with the cork out, from time to time; in the course of two or three days it will be fit for use. This will be found an admirable liquid to add to any colour, as it not only brightens it, but renders it less likely to fade from exposure to the air.
