Part 382

IV.—Oxalic acid 1⁠/⁠2 av. ounce Rotten stone 10 av. ounces Kerosene (coal oil) 30 fluidounces Paraffine 2 av. ounces

Pulverize the oxalic acid and mix it with rotten stone; melt the paraffine, add to it the kerosene, and incorporate the powder; when cool, add oil of mirbane or lavender to perfume.

Pour the ammonia into the oil, methylated spirits, and turpentine, add the camphorated spirit and mix with the kieselguhr. To prevent setting, keep well agitated during filling. The color may be turned red by using a little sesquioxide of iron and less kieselguhr. Apply with a cloth, and when dry use another clean cloth or a brush.

«Polishing Soaps.»—

I.—Powdered pipe clay 112 pounds Tallow soap 16 pounds Tartaric acid 1 1⁠/⁠4 pounds

Grind until pasty, afterwards press into blocks by the machine.

II.—Levigated flint 60 pounds Whiting 52 pounds Tallow 20 pounds Caustic soda 5 pounds Water 2 gallons

Dissolve the soda in water and add to the tallow; when saponified, stir in the others, pressing as before.

III.—Saponified cocoanut oil 56 pounds Kieselguhr 12 pounds Alum 5 1⁠/⁠2 pounds Flake white 5 1⁠/⁠2 pounds Tartaric acid 1 3⁠/⁠4 pounds

Make as before.

IV.—Tallow soap 98 pounds Liquid glycerine soap 14 pounds Whiting 18 pounds Levigated flint 14 pounds Powdered pipe clay 14 pounds

«METAL POLISHES:»

«Polishing Pastes.»—

I.—White petroleum jelly 90 pounds Kieselguhr 30 pounds Refined paraffine wax 10 pounds Refined chalk or whiting 10 pounds Sodium hyposulphite 8 pounds

Melt wax and jelly, stir in others and grind.

It is an undecided point as to whether a scented paste is better than one without perfume. The latter is added merely to hide the nasty smell of some of the greases used, and it is not very nice to have spoons, etc., smelling, even tasting, of mirbane, so perhaps citronelle is best for this purpose. It is likely to be more pure. The dose of scent is usually at the rate of 4 ounces to the hundredweight.

II.—Dehydrated soda 5 parts Curd soap 20 parts Emery flour 100 parts

To be stirred together on a water bath with water, 100 parts, until soft.

III.—Turpentine 1 part Emery flour 1 part Paris red 2 parts Vaseline 2 parts

Mix well and perfume.

IV.—Stearine 8 to 9 parts Mutton suet 32 to 38 parts Stearine oil 2 to 2.5 parts

Melt together and mix with Vienna chalk, in fine powder, 48 to 60 parts; Paris red, 20 parts.

V.—Rotten stone 1 part Iron subcarbonate 3 parts Lard oil, a sufficient quantity.

VI.—Iron oxide 10 parts Pumice stone 32 parts Oleic acid, a sufficient quantity.

VII.—Soap, cut fine 16 parts Precipitated chalk 2 parts Jewelers’ rouge 1 part Cream of tartar 1 part Magnesium carbonate 1 part Water, a sufficient quantity.

Dissolve the soap in the smallest quantity of water over a water bath. Add the other ingredients to the solution while still hot, stirring all the time to make sure of complete homogeneity. Pour the mass into a box with shallow sides, and afterwards cut into cubes.

«Non-Explosive Liquid Metal Polish.»—Although in a liquid form, it does not necessarily follow that a liquid polish is less economical than pastes, because the efficiency of both is dependent upon the amount of stearic or oleic acid they contain, and a liquid such as that given below is as rich in this respect as most of the pastes, especially those containing much mineral jelly and earthy matters which are practically inert, and can only be considered as filling material. Thus it is a fact that an ounce of fluid polish may possess more polishing potency than an equal weight of the paste. Proportions are: Sixteen pounds crude oleic acid; 4 pounds tasteless mineral oil; 5 pounds kieselguhr; 1 1⁠/⁠2 ounces lemon oil. Make the earthy matter into a paste with the mixed fluids and gradually thin out, avoiding lumps. Apply with one rag, and finish with another.
