106. Plain Hints about Candles.—Candles improve by keeping a few months. Those made in winter are the best. The most economical, as well as the most convenient plan, is to purchase them by the box, keeping them always in a cool, dry place. If wax candles become discolored or soiled, they may be restored by rubbing them over with a clean flannel slightly dipped in spirits of wine. Candles are sometimes difficult to light. They will ignite instantly, if, when preparing them for the evening, you dip the top in spirits of wine, shortly before they are wanted. Light them always with a match, and do not hold them to the fire, as that will cause the tops to melt and drip. Always hold the match to the side of the wick, and not over the top. If you find the candles too small for the candlesticks, always wrap a small piece of white paper round the bottom end, not allowing the paper to appear above the socket. Cut the wicks to a convenient length for lighting (nearly close); for if the wick is too long at the top, it will be very difficult to ignite, and will also bend down, and set the candle to running. Glass receivers, for the droppings of candles, are very convenient, as well as ornamental. The pieces of candles that are left each evening should be placed in a tin box kept for that purpose, and used for bed lights.
107. To make an improved Candle.—Make the wicks about half the usual size, and wet them with spirits of turpentine; dry them, before dipping, in the sunshine, or in some favorable place, and the candles will be more durable, emit a steadier and clearer blaze, and be in every way superior to those made in the ordinary way.
108. Quicksilver.—Tallow will take up quicksilver. Vinegar kills it.
109. To give any Close-grained Wood the appearance of Mahogany.—The surface of the wood must first be planed smooth, and then rubbed with weak aquafortis; after which it is to be finished with the following varnish:—To three pints of spirit of wine is to be added four ounces and a half of dragon's blood and an ounce of soda, which have been previously ground together; after standing some time, that the dragon's blood may dissolve, the varnish is to be strained, and laid on the wood with a soft brush. This process is to be repeated, and then the wood possesses the perfect appearance of mahogany. When the polish diminishes in brilliancy, it may be speedily restored by rubbing the article with linseed oil.
110. To Darken Mahogany.—Drop a nodule of lime in a basin of water, and wash the mahogany with it.
