r Prints to Glass.--First coat the glass with
dammar varnish, or else with Canada balsam, mixed with an equal volume
of oil of turpentine, and let it dry until it is very sticky, which
takes half a day or more. The printed paper to be transferred should
be well soaked in soft water, and carefully laid upon the prepared
glass, after removing surplus water with blotting paper, and pressed
upon it, so that no air bubbles or drops of water are seen underneath.
This should dry a whole day before it is touched; then with wetted
fingers begin to rub off the paper at the back. If this be skillfully
done, almost the whole of the paper can be removed, leaving simply the
ink upon the varnish. When the paper has been removed, another coat of
varnish will serve to make the whole more transparent. This recipe is
sold at from $3 to $5 by itinerants.
A Liquid Cement for Cementing Leather, that Will Not be Affected by
the Action of Water.--A good cement for splicing leather is gutta
percha dissolved in carbon disulphide, until it is of the thickness
of treacle; the parts to be cemented must first be well thinned down,
then pour a small quantity of the cement on both ends, spreading it
well so as to fill the pores of the leather; warm the parts over a
fire for about half a minute, apply them quickly together, and hammer
well. The bottle containing the cement should be tightly corked, and
kept in a cool place.
The Quickest and Best Way to Drill Holes for Water Pipes in Rough
Plate Glass.--Use a hardened (file temper) drill, with spirits of
turpentine and camphor to make the drill bite. A broken file in a
breast brace will do good work if a power drill is not obtainable.
A Recipe for Making Printers' Inks.--For black ink: Take of balsam of
copaiba (pure), 9 ounces; lamp black, 3 ounces; indigo and Prussian
blue, of each half an ounce; Indian red, 3/4 ounce; yellow soap (dry),
3 ounces; grind the mixture to an impalpable smoothness by means of
a stone and muller. Canada balsam may be substituted for balsam of
copaiba where the smell of the latter is objectionable, but the ink
then dries very quickly. The red inks are similarly made by using such
pigments as carmine, lakes, vermilion, chrome yellow, red lead, orange
red, Indian red and Venetian red.
A Cement to Stick White Metal Tops on Glass Bottles.--One of the best
cap cements consists of resin, 5 ounces; beeswax, 1 ounce; red ocher
or Venetian red in powder, 1 ounce. Dry the eart
