ole into a
kind of paste. With this paste join the pieces of china, or glass, and
press them together for seven or eight minutes. This cement will stand
both heat and water, and will never give way, even if the article
should, by accident, fall to the ground.
_To remove Stains and Blemishes from Prints._
Paste a piece of paper to a very smooth clear table, that the boiling
water used in the operation may not require a colour which might
lessen its success. Spread out the print you wish to clean upon the
table, and sprinkle it with boiling water; taking care to moisten it
throughout by very carefully applying a very fine sponge. After you
have repeated this process five or six times, you will observe the
stains or spots extend themselves; but this is only a proof that the
dirt begins to be dissolved.
After this preparation, lay the print smoothly and carefully into a
copper or wooden vessel, larger than the size of the print. Then cover
it with a boiling ley of potash, taking care to keep it hot as long as
possible. After the whole is cooled, strain off the liquor, take out
the print with care, spread it on a stretched cord, and when half dry,
press it between leaves of white paper, to prevent wrinkles.
By this process, spots and stains of any kind will be effectually
removed.
_To so fill a Glass with Water, that it cannot be removed without
spilling the whole._
This is a mere trick, but may afford some amusement. You offer to bet
any person that you will so fill a glass with water that he shall not
move it off the table without spilling the whole contents. You then
fill the glass, and, laying a piece of paper or thin card over the
top, you dexterously turn the glass upside down on the table, and then
drawing away the paper, you leave the water in the glass, with its
foot upwards. It will therefore be impossible to remove the glass from
the table without spilling every drop.
_Two Figures, one of which blows out and the other re-lights a
Candle._
Make two figures, of any shape or materials you please; insert in the
mouth of one a small tube, at the end of which is a piece of
phosphorus, and in the mouth of the other a tube containing at the end
a few grains of gunpowder; taking care that each be retained in the
tube by a piece of paper. If the second figure be applied to the flame
of a taper, it will extinguish it; and the first will light it again.
