TO EXTRACT GREASE WITH CAMPHINE OIL.--Grease of the very worst sort (for instance whale oil) may be extracted successfully even from silks, ribbons, and other delicate articles, by means of camphine oil, which can always be procured at the lamp-stores. As this oil is best when fresh, get but a small quantity at a time. Pour some camphine into a clean cup, and dip lightly into it a bit of clean, soft, white rag. With this rub the grease spot. Then take a fresh rag dipped in the camphine, and continue rubbing till the grease is extracted, which will be very soon. You will find the colour of the article uninjured. To remove the turpentine odour of the camphine, rub the place with cologne water or strong spirits of wine, and expose it to the open air. If any of the camphine-scent remains, repeat the cologne. We have known lamp oil removed from white satin by this process.
FINE YELLOW COLOURING FOR WALLS.--Procure from a paint-shop one pound of chrome yellow, and three pounds of whiting. Mix and grind them thoroughly together; and then add a quart of boiling water, and stir it well in. Next boil a quarter of a pound of glue in a quart of water, and when completely dissolved, add it immediately to the mixture, and stir the whole very hard. Thin it with more water till you get it of the desired consistence. It will be a beautiful yellow, approaching to lemon colour.
BLUE WASH FOR WALLS.--Get a pound of blue vitriol from a drug or paint store, and have it powdered very finely in a mortar. Provide also two quarts of lime. Take six cents' worth of glue, and boil it in a quart of soft water till thoroughly dissolved. Put the powdered vitriol into a wooden bucket, and when the glue-water is cold, pour it on the vitriol, and mix and stir it well. When the vitriol is dissolved in the glue-water, stir in by degrees the two quarts of lime. Then try the tint of the mixture by dipping a piece of white paper into it; and when it dries, you can judge if it is the colour you want. It should be a clear light beautiful blue. If you think it too dark, add some more lime. If too pale, stir in a little more of the powdered vitriol. It is well to provide an extra quantity of each of the articles, in case a little more of one or the other should be required on trial of the colour.
