A very fine crimson stain may be given to paper by a tincture of Indian lake, which may be made by infusing the lake some days in spirits of wine, and then pouring off the tincture from the dregs. It may * be stained red by red ink. It may also be stained of a scarlet hue by the tincture of dragon's-blood in spirits of wine, but this will not be bright.
Stain the paper first of a full yellow by means of tincture of turmeric; then brush it over with a solution of fixed alkaline salt, made by dissolving 1/2 oz. of pearlash, or salts of tartar, in a quart of water, and filtering the solution.
Paper may be stained purple by archil or by tincture of logwood. Brush the work several times with the following logwood decoction: - 1 lb. of logwood chips, 1/4 lb. of Brazil wood, boiled for 1 1/2 hour in a gallon of water. When dry, give a coat of pearlash solution, 1 dram to a quart, taking care to lay it on evenly. The juice of ripe privet berries expressed will also give a purple dye.
Paper may be stained a beautiful yellow by tincture of turmeric formed by infusing an ounce or more of the root, powdered, in a pint of spirits of wine. This may be made to give any tint of yellow, from the lightest straw to the full colour, called French yellow, and will be equal in brightness to the best dyed silks. If yellow be wanted of a warmer or redder cast, annatto or dragon's blood must be added. The best manner of using these is to spread them evenly on the paper by means of a broad brush, in the manner of varnishing.
