This is the best preparation, but one in which the beeswax is merely

dissolved in the turpentine in such a way as to have the consistence of

a not too thin oil color, will answer. The wood is treated with this,

taking care that the surface is evenly covered with the mixture, and

that it does not sink too deeply in the ornaments, corners, etc., of

the woodwork. This is best achieved by taking care to scrape off from

the cloths all excess of the wax.

If, in the course of 24 hours, the surface is hard, then with a stiff

brush go over it, much after the way of polishing a boot. For the

corners and angles smaller brushes are used; when necessary, stiff

pencils may be employed. Finally, the whole is polished with plush,

or velvet rags, in order not to injure the original polish. Give the

article a good coat of linseed oil or a washing with petroleum before

beginning work.

II.—Articles that are always exposed to the water, floors, doors,

especially of oak, should, from time to time, be {755} saturated with

oil or wax. A house door, plentifully decorated with wood carving,

will not shrink or warp, even where the sun shines hottest on it, when

it is frequently treated to saturation with wax and oil. Here a plain

dosage with linseed oil is sufficient. Varnish, without the addition of

turpentine, should never be used, or if used it should be followed by a

coat of wax.

III.—A good floor wax is composed of 2 parts of wax and 3 parts of

Venice turpentine, melted on the water bath, and the mixture applied

while still hot, using a pencil, or brush, for the application, and

when it has become solid and dry, diligently rubbed, or polished down

with a woolen cloth, or with a floor brush, especially made for the

purpose.

IV.—An emulsion of 5 parts of yellow wax, 2 parts of crude potassium

carbonate, and 12 parts of water, boiled together until they assume a

milky color and the solids are dissolved, used cold, makes an excellent

composition for floors. Any desired color may be given this dressing by

stirring in the powdered coloring matter. Use it exactly as described

for the first mass.

«Gilders’ Wax.»—For the production of various colorings of gold in fire

gilding, the respective places are frequently covered with so-called

gilders’ wax. These consist of mixtures of various chemicals which

have an etching action in the red heat upon the bronze mass, thus

causing roughness of unequal depth, as well as through the fact that

the composition of the bronze is changed somewhat on the surface, a

relief of the gold color being effected in consequence of these two

circumstances. The gilding wax is prepared by melting together the

finely powdered chemicals with wax according to the following recipes:

I II III IV V

Dissolve the wax in the oil by aid of a low heat, on a water bath. Mix

the remaining ingredients, which must be well powdered, and work up

with a portion of the solution of wax. Finally, add the mixture to the

solution, and mix thoroughly on the bath. When a homogeneous liquid is

obtained, pour into earthen boxes.

«Modeling Wax.»—I.—Yellow wax, 1,000 parts; Venice turpentine, 130

parts; lard, 65 parts; bole, 725 parts. The mixture when still liquid

is poured into tepid water and kneaded until a plastic mass is obtained.

II.—Summer Modeling Wax.—White wax, 20 parts; ordinary turpentine, 4

parts; sesame oil, 1 part; vermilion, 2 parts.

III.—Winter Modeling Wax.—White wax, 20 parts; ordinary turpentine, 6

parts; sesame oil, 2 parts; vermilion, 2 parts. Preparation same as for

Formula I.

«Sealing Waxes.»—The following formulas may be followed for making

sealing wax: Take 4 pounds of shellac, 1 pound of Venice turpentine,

and 3 pounds of vermilion. Melt the lac in a copper pan suspended over

a clear charcoal fire, then add the turpentine slowly to it, and soon

afterwards add the vermilion, stirring briskly all the time with a rod

in either hand. In forming the round sticks of sealing wax, a certain

portion of the mass should be weighed while it is ductile, divided into

the desired number of pieces, and then rolled out upon a warm marble

slab by means of a smooth wooden block like that used by apothecaries

for rolling a mass of pills.

The oval and square sticks of sealing wax are cast in molds, with

the above compound, in a state of fusion. The marks of the lines of

junction of the mold box may be afterwards removed by holding the

sticks over a clear fire, or passing them over a blue gas flame.

Marbled sealing wax is made by mixing {756} two, three, or more colored

kinds together while they are in a semi-fluid state. From the viscidity

of the several portions their incorporation is left incomplete, so as

to produce the appearance of marbling. Gold sealing wax is made simply

by adding gold chrome instead of vermilion into the melted rosins. Wax

may be scented by introducing a little essential oil, essence of musk,

or other perfume. If 1 part of balsam of Peru be melted along with 99

parts of the sealing-wax composition, an agreeable fragrance will be

exhaled in the act of sealing with it. Either lampblack or ivory black

serves for the coloring matter of black wax. Sealing wax is often

adulterated with rosin, in which case it runs into thin drops at the

flame of a candle.

The following mistakes are sometimes made in the manufacture of sealing

wax:

I.—Use of filling agents which are too coarsely ground.

II.—Excessive use of filling agents.

III.—Insufficient binding of the pigments and fillings with a suitable

adhesive agent, which causes these bodies to absorb the adhesive power

of the gums.

IV.—Excessive heating of the mass, caused by improper melting or faulty

admixture of the gummy bodies. Turpentine and rosin must be heated

before entering the shellac. If this rule is inverted, as is often the

case, the shellac sticks to the bottom and burns partly.

Great care must be taken to mix the coloring matter to a paste with

spirit or oil of turpentine before adding to the other ingredients.

Unless this is done the wax will not be of a regular tint.

«Dark Blue Wax.»—Three ounces Venetian turpentine, 4 ounces shellac, 1

ounce rosin, 1 ounce Prussian blue, 1⁠/⁠2 ounce magnesia.

«Green Wax.»—Two ounces Venetian turpentine, 4 ounces shellac, 1 1⁠/⁠4

ounces rosin, 1⁠/⁠2 ounce chrome yellow, 1⁠/⁠4 ounce Prussian blue, 1

ounce magnesia.

«Carmine Red Wax.»—One ounce Venetian turpentine, 4 ounces shellac, 1

ounce rosin, colophony, 1 1⁠/⁠4 ounces Chinese red, 1 drachm magnesia,

with oil of turpentine.

«Gold Wax.»—Four ounces Venetian turpentine, 8 ounces shellac, 14

sheets of genuine leaf gold, 1⁠/⁠2 ounce bronze, 1⁠/⁠2 ounce magnesia,

with oil of turpentine.

«White Wax.»—I.—The wax is bleached by exposing to moist air and to

the sun, but it must first be prepared in thin sheets or ribbons or in

grains. For this purpose it is first washed, to free it from the honey

which may adhere, melted, and poured into a tin vessel, whose bottom

is perforated with narrow slits. The melted wax falls in a thin stream

on a wooden cylinder arranged below and half immersed in cold water.

This cylinder is turned, and the wax, rolling round in thin leaves,

afterwards falls into the water. To melt it in grains, a vessel is made

use of, perforated with small openings, which can be rotated. The wax

is projected in grains into the cold water. It is spread on frames of

muslin, moistened with water several times a day, and exposed to the

sun until the wax assumes a fine white. This whiteness, however, is not

perfect. The operation of melting and separating into ribbons or grains

must be renewed. Finally, it is melted and flowed into molds. The

duration of the bleaching may be abridged by adding to the wax, treated

as above, from 1.25 to 1.75 per cent of rectified oil of turpentine,

free from rosin. In 6 or 8 days a result will be secured which would

otherwise require 5 or 6 weeks.

II.—Bleached shellac 28 parts

Venetian turpentine 13 parts

Plaster of Paris 30 parts

«Weather Forecasters»

(See also Hygrometers and Hygroscopes.)

I.—It is known that a leaf of blotting paper or a strip of fabric made

to change color according to the hygrometric state of the atmosphere

has been employed for weather indications in place of a barometer. The

following compound is recommended for this purpose: One part of cobalt

chloride, 75 parts of nickel oxide, 20 parts of gelatin, and 200 parts

of water. A strip of calico, soaked in this solution, will appear green

in fine weather, but when moisture intervenes the color disappears.

{757}

II.—Copper chloride 1 part

Gelatin 10 parts

Water 100 parts

III.—This is a method of making old-fashioned weather glasses

containing a liquid that clouds or solidifies under certain atmospheric

conditions:

Camphor 2 1⁠/⁠2 drachms

Alcohol 11 drachms

Water 9 drachms

Saltpeter 38 grains

Sal ammoniac 38 grains

Dissolve the camphor in the alcohol and the salts in the water and

mix the solutions together. Pour in test tubes, cover with wax after

corking and make a hole through the cork with a red-hot needle, or draw

out the tube until only a pin hole remains. When the camphor, etc.,

appear soft and powdery, and almost filling the tube, rain with south

or southwest winds may be expected; when crystalline, north, northeast,

or northwest winds, with fine weather, may be expected; when a portion

crystallizes on one side of the tube, wind may be expected from that

direction. Fine weather: The substance remains entirely at bottom of

tube and the liquid perfectly clear. Coming rain: Substance will rise

gradually, liquid will be very clear, with a small star in motion. A

coming storm or very high wind: Substance partly at top of tube, and

of a leaflike form, liquid very heavy and in a fermenting state. These

effects are noticeable 24 hours before the change sets in. In winter:

Generally the substance lies higher in the tube. Snow or white frost:

Substance very white and small stars in motion. Summer weather: The

substance will lie quite low. The substance will lie closer to the tube

on the opposite side to the quarter from which the storm is coming. The

instrument is nothing more than a scientific toy.

_For measuring surfaces_, the square dekameter is used under the term

of ARE; the hectare, or 100 ares, is equal to about 2 1⁠/⁠2 acres.

_The unit of capacity_ is the cubic decimeter or LITER, and the series

of measures is formed in the same way as in the case of the table of

lengths. The cubic meter is the unit of measure for solid bodies,

and is termed STERE. _The unit of weight_ is the GRAM, which is the

weight of one cubic centimeter of pure water weighed in a vacuum at the

temperature of 4° C. or 39.2° F., which is about its temperature of

maximum density. In practice, the term cubic centimeter, abbreviated

c.c., is generally used instead of milliliter, and cubic meter instead

of kiloliter. {760}

«WELDING POWDERS.»

See also Steel.

«Powder to Weld Wrought Iron at Pale-red Heat with Wrought

Iron.»—I.—Borax, 1 part (by weight); sal ammoniac, 1⁠/⁠2 part; water,

1⁠/⁠2 part. These ingredients are boiled with constant stirring until

the mass is stiff; then it is allowed to harden over the fire. Upon

cooling, the mass is rubbed up into a powder and mixed with one-third

wrought-iron filings free from rust. When the iron has reached red

heat, this powder is sprinkled on the parts to be welded, and after it

has liquefied, a few blows are sufficient to unite the pieces.

II.—Borax, 2 parts; wrought-iron filings, free from rust, 2 parts; sal

ammoniac, 1 part. These pulverized parts are moistened with copaiba

balsam and made into a paste, then slowly dried over a fire and again

powdered. The application is the same as for Formula I.

«Welding Powder to Weld Steel on Wrought Iron at Pale-red Heat.»—Borax,

3 parts; potassium cyanide, 2 parts; Berlin blue, 1–100 part. These

substances are powdered well, moistened with water; next they are

boiled with constant stirring until stiff; then dry over a fire.

Upon cooling, the mass is finely pulverized and mixed with 1 part

of wrought-iron filings, free from rust. This powder is sprinkled

repeatedly upon the hot pieces, and after it has burned in the welding

is taken in hand.

WHEEL GREASE: See Lubricants.

«WHETSTONES.»

To make artificial whetstones, take gelatin of good quality, dissolve

it in equal weight of water, operating in almost complete darkness,

and add 1 1⁠/⁠2 per cent of bichromate of potash, previously dissolved.

Next take about 9 times the weight of the gelatin employed of very

fine emery or fine powdered gun stone, which is mixed intimately with

the gelatinized solution. The paste thus obtained is molded into the

desired shape, taking care to exercise an energetic pressure in order

to consolidate the mass. Finally dry by exposure to the sun.

«WHITING:»

«To Form Masses of Whiting.»—Mix the whiting into a stiff paste with

water, and the mass will retain its coherence when dry.
