Pass them through a warm liquor of bullock’s gall and water; rinse in cold water; then take a small piece of glue, pour boiling water on it, and pass the veil through it; clap it, and frame it to dry. TO CLEAN WHITE SATIN AND FLOWERED SILKS. Mix sifted stale bread crumbs with powder-blue, and rub it thoroughly all over, then shake it well, and dust it with clean soft cloths. Afterwards, where there are any gold or silver flowers, take a piece of crimson in grain velvet, rub the flowers with it, which will restore them to their original lustre. _Another Method._ Pass them through a solution of fine hard soap, at a hand heat, drawing them through the hand. Rinse in lukewarm water, dry and finish by pinning out. Brush the flossy or bright side with a clean clothes brush, the way of the nap. Finish them by dipping a sponge into a size, made by boiling isinglass in water, and rub the wrong side. Rinse out a second time, and brush and dry near a fire, or in a warm room. Silks may be treated in the same way, but not brushed. If the silks are for dyeing, instead of passing them through a solution of soap and water, they must be boiled off; but if the silks are very stout, the water must only be of heat sufficient to extract the dirt, and when rinsed in warm water they are in a state for the dye. _Another Method._ Strew French chalk over them, and brush it off with a hard brush once or twice. TO CLEAN COLOURED SILKS OF ALL KINDS. Put some soft soap into boiling water, and beat it till dissolved in a strong lather. At a hand heat put in the article. If strong, it may be rubbed as in washing; rinse it quickly in warm water, and add oil of vitriol, sufficient to give another water a sourish taste, if for bright yellows, crimsons, maroons, and scarlets; but for oranges, fawns, browns, or their shades, use no acid. For bright scarlet use a solution of tin. Gently squeeze, and then roll it in a coarse sheet, and wring it. Hang it in a warm room to dry, and finish it by calendering or mangling. For pinks, rose colours, and thin shades, &c., instead of oil of vitriol, or solution of tin, prefer lemon juice, or white tartar, or vinegar. For blues, purples, and their shades, add a small quantity of American pearl-ash; it will restore the colours. Wash the articles like a linen garment, but instead of wringing, gently squeeze and sheet them, and when dry, finish them with fine gum water, or dissolved isinglass, to which add some pearl-ash, rubbed on the wrong side, then pin them out. Blues of all shades are dyed with archil, and afterwards dipped in a vat; twice cleaning with pearl-ash, restores the colour. For olive greens, a small quantity of verdigris dissolved in water, or a solution of copper, mixed with the water, will revive the colour again. TO CLEAN BLACK SILKS.
