near the fire to make sure; then polish off with a clean flannel cloth and a
little sweet oil.
TO MAKE A PASTE OR MUCILAGE TO FASTEN LABELS.
Soften good glue in water, then boil it with strong vinegar, and thicken the
liquid, during boiling, with fine wheat flour, so that a paste results; or
starch paste, with which a little Venice turpentine has been incorporated while
it was warm.
A recipe for a transparent cement which possesses great tenacity and has not the
slightest yellow tinge: Mix in a well-stoppered bottle ten drachms of chloroform
with ten and one-half of non-vulcanized caoutchouc (rubber) cut in small pieces.
Solution is readily effected, and when it is completed add two and one-half
drachms of mastic. Let the whole macerate from eight to ten days without the
application of any heat, and shake the contents of the bottle at intervals. A
perfectly white and very adhesive cement is the result.
POSTAGE STAMP MUCILAGE.
Take of gum dextrine, two parts; acetic acid, one part; water, five parts.
Dissolve in a water bath and add alcohol one part.
--Scientific American.
Gum of great strength, which will also keep for a long time, is prepared by
dissolving equal parts of gum arabic and gum tragacanth in vinegar. A little
vinegar added to ordinary gum water will make it keep much better.
FAMILY GLUE.
Crack the glue and put it in a bottle; add common whiskey; shake up, cork tight,
and in three or four days it can be used. It requires no heating, will keep for
almost any length of time, and is at all times ready to use, except in the
coldest of weather, when it will require warming. It must be kept tight, so that
the whiskey will not evaporate. The usual corks or stoppers should not be used.
It will become clogged. A tin stopper covering the bottle, but fitting as
closely as possible, must be used.
GLUE.
Glue to resist heat and moisture is made as follows: Mix a handful of quick-lime
in four ounces of linseed oil, boil to a good thickness, then spread it on tin
plates in the shade, and it will become very hard, but may be easily dissolved
over the fire as glue.
A glue which will resist the action of water is made by boiling one pound of
common glue in two quarts of skimmed milk.
