TO RENOVATE BLACK SILK.—Slice some uncooked potatoes, pour boiling water on them; when cold sponge the right side of the silk with it, and iron on the wrong.—E. H. TO MAKE OLD SILK GOWNS LOOK LIKE NEW.—The best method, and one that is employed by milliners, is to sponge over the outside of the dress with a strong and cold infusion of black tea. The dress should afterwards be ironed on the wrong side.—K. AN EXCELLENT YELLOW DYE FOR SILKS, RIBBONS, ETC.—Take a large handful of horse-radish leaves, boil them in two quarts of water for half an hour; then drain it off from the leaves, and soak the articles you have for dyeing in it; when you think the colour deep enough, take it out, rinse it in cold water, and spread it to dry.—B. B. TO IRON SILK.—Silk cannot be ironed smoothly, so as to press out all the creases, without first sprinkling it with water, and rolling it up tightly in a towel, letting it rest for an hour or two. If the iron is in the least too hot, it will injure the colour, and it should first be tried on an old piece of the same silk.—C. C. TO RENOVATE SILKS.—Sponge faded silks with warm water and soap; then rub them with a dry cloth on a flat board; afterwards iron them on the _inside_ with a smoothing-iron. Old black silks may be improved by sponging with spirits. In this case, the ironing may be done on the right side, thin paper being spread over to prevent glazing. TO DYE SILK, ETC., CRIMSON.—Take about a spoonful of cutbear, put it into a small pan, pour boiling water upon it; stir and let it stand a few minutes, then put in the silk, and turn it over in a short time, and when the colour is full enough, take it out; but if it should require more violet or crimson, add a spoonful or two of purple archil to some warm water; steep, and dry it within doors. To finish it, it must be mangled, and ought to be pressed. SILKS STAINED BY CORROSIVE OR SHARP LIQUORS.—We often find that lemon-juice, vinegar, oil of vitriol, and other sharp corrosives, stain dyed garments; sometimes by adding a little pearlash to a soap lather, and passing the silks through these, the faded colour will be restored. Pearlash and warm water will sometimes do alone, but it is the most efficacious method to use the soap lather and pearlash together. CHEMICAL RENOVATING BALLS—for taking out grease, paint, pitch tar, from silks, stuffs, linen, woollen, carpets, hats, coats, &c., without fading the colour or injuring the cloth:—Quarter ounce of fuller’s earth, quarter ounce of pipe-clay, one ounce salt of tartar, one ounce beef gall, one ounce spirits of wine. Pound the hard parts, and mix the ingredients well together. Wet the stain with cold water, rub it well with this ball, then sponge it with a wet sponge, and the stain will disappear.
