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

Red chalk 3 24 18 48 18

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

(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.

«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.
