Part 90

Melt on the steam bath and add to the hot mass:

Coumarin 2 parts Mirbane oil 10 parts

Cast in plates or compressed tablets. The preparation is employed as a moth preventive.

«Powdered Camphor in Permanent Form.»—I.—Powder the camphor in the usual manner, with the addition of a little alcohol. When it is nearly reduced to the proper degree of fineness add a few drops of fluid petrolatum and immediately triturate again. In this manner a powder as fine as flour is obtained, which does not cake together. This powdered camphor may be used for all purposes except for solution in alcohol, as it will impart to the latter a faint opalescence, owing to the insolubility of the petrolatum.

II.—Take equal parts of strong ether and alcohol to reduce the camphor to powder. It is claimed for this method that it only takes one-half of the time required when alcohol alone is used, and that the camphor dries more quickly. Before sifting add 1 per cent of white vaseline and 5 per cent of sugar of milk. Triturate fairly dry, spread out in the air, say 15 minutes, then pass through a moderately fine wire sieve, using a stubby shaving brush to assist in working it through. {145}

«Camphor Pomade»—

Oil of bitter almonds 1 drachm Oil of cloves 20 drops Camphor 1 1⁠/⁠2 ounces White wax 4 ounces Lard, prepared 1 pound

Melt the wax and lard together, then add the camphor in saturated solution in spirit; put in the oils when nearly cold.

«Camphor Ice.»—

I.—White wax 16 parts Benzoated suet 48 parts Camphor, powdered 8 parts Essential oil, to perfume.

Melt the wax and suet together. When nearly cold, add the camphor and perfume, mix well, and pour into molds.

II.—Oil of almond 16 parts White wax 4 parts Spermaceti 4 parts Paraffine 8 parts Camphor, powdered 1 part Perfume, quantity sufficient.

Dissolve the camphor in the oil by the aid of a gentle heat. Melt the solids together, remove, and let cool, but before the mixture begins to set add the camphorated oil and the perfume, mix, and pour into molds.

III.—Stearine (stearic acid) 8 pounds Lard 10 pounds White wax 5 pounds Spermaceti 5 pounds

Melt on a water bath in an earthen or porcelain dish; strain into a similar vessel; add a solution of 2 ounces powdered borax in 1 pound of glycerine, previously warmed, to the melted substance when at the point of cooling; stir well; add camphor, 2 pounds, powdered by means of alcohol, 3 ounces; stir well and pour into molds.

«CANARY-BIRD PASTE.»

The following is a formula much used by German canary-bird raisers:

Sweet almonds, blanched 16 parts Pea meal 32 parts Butter, fresh (unsalted) 3 parts Honey, quantity sufficient to make a stiff paste.

The ingredients are worked into a stiff paste, which is pressed through a colander or large sieve to granulate the mass. Some add to every 5 pounds, 10 or 15 grains of saffron and the yolks of 2 eggs.

«CANDLES:»

«Coloring Ceresine Candles for the Christmas Tree.»—For coloring these candles only dye stuffs soluble in oil can be employed. Blue: 23–24 lavender blue, pale or dark, 100–120 parts per 5,000 parts of ceresine. Violet: 26 fast violet R, 150 parts per 5,000 parts of ceresine. Silver gray: 29 silver gray, 150 parts per 5,000 parts of ceresine. Yellow and orange: 30 wax yellow, medium, 200 parts per 5,000 parts of ceresine; 61 old gold, 200 parts per 5,000 parts of ceresine. Pink and red: 27 peach-pink, or 29 chamois, about 100 parts per 5,000 parts of ceresine. Green: 16–17 brilliant green, 33 May green, 41 May green, 200–250 parts per 5,000 parts of ceresine. The above-named colors should be ground in oil and the ceresine tinted with them afterwards.

«Manufacture of Composite Paraffine Candles.»—Three parts of hydroxy-stearic acid are dissolved in 1 part of a suitable solvent (e. g., stearic acid), and the solution is mixed with paraffine wax to form a stock for the manufacture of composite candles.

«Transparent Candles.»—The following are two recipes given in a German patent specification. The figures denote parts by weight:

I.—Paraffine wax, 70; stearine, 15; petroleum, 15.
