Green tea is excellent to restore rusty silk. It should be boiled in
iron, nearly a cup full to three quarts. The silk should not be wrung,
and should be ironed damp.

Lime pulverized, sifted through coarse muslin, and stirred up
tolerably thick in white of eggs, makes a strong cement for glass
and china. Plaster of Paris is still better; particularly for mending
broken images of the same material. It should be stirred up by the
spoonful, as it is wanted.[2]

[Footnote 2: Some think it an improvement to make whey of vinegar and
milk, and heat it well up with the eggs before the lime is put in. I
have heard of iron mended with it.]

A bit of isinglass dissolved in gin, or boiled in spirits of wine, is
said to make strong cement for broken glass, china, and sea-shells.

The lemon syrup, usually sold at fifty cents a bottle, may be made
much cheaper. Those who use a great quantity of it will find it worth
their while to make it. Take about a pound of Havana sugar; boil it
in water down to a quart; drop in the white of an egg, to clarify it;
strain it; add one quarter of an oz. of tartaric acid, or citric acid;
if you do not find it sour enough, after it has stood two or three
days and shaken freely, add more of the acid. A few drops of the oil
of lemon improves it.

If you wish to clarify sugar and water, you are about to boil, it is
well to stir in the white of one egg, while cold; if put in after it
boils, the egg is apt to get hardened before it can do any good.
