k color. Stir the whole well together, and
add, when taken from the fire, half a glass of rum.

396. _Liquid Blacking._

Mix a quarter of a pound of ivory black, six gills of vinegar, a
table-spoonful of sweet oil, two large spoonsful of molasses. Stir the
whole well together, and it will then be fit for use.

397. _Cement for the Mouths of Corked Bottles._

Melt together a quarter of a pound of sealing-wax, the same quantity of
rosin, a couple of ounces of bees' wax. When it froths, stir it with a
tallow candle. As soon as it melts, dip the mouths of the corked bottles
into it. This is an excellent thing to exclude the air from such things
as are injured by being exposed to it.

398. _Cement for broken China, Glass, and Earthenware._

Rub the edge of the china or glass with the beaten white of an egg. Tie
very finely powdered quick lime in a muslin bag, and sift it thick over
the edges of the dishes that have been previously rubbed with the egg.
Match and bind the pieces together, and let it remain bound several
weeks. This is good cement for every kind of crockery but thick heavy
glass and coarse earthenware; the former cannot be cemented with any
thing; for the latter, white paint will answer. Paint and match the
broken edges, bind them tight together, and let them remain until the
paint becomes dry and hard. Milk is a good cement for crockery--the
pieces should be matched, and bound together tight, then put in cold
milk, and the milk set where it will boil for half an hour; then take it
from the fire, and let the crockery remain till the milk is cold. Let
the crockery remain bound for several weeks. The Chinese method of
mending broken china, is to grind flint glass, on a painter's stone,
till it is reduced to an impalpable powder: then beat it with the white
of an egg, to a froth, and lay it on the edge of the broken pieces,
match and bind them together firmly, and let them remain several weeks.
It is said that no art will then be able to break it in the same place.

399. _Japanese Cement, or Rice Glue._

Mix rice flour with cold water, to a smooth paste, and boil it gently.
It answers all the purposes of wheat flour paste, while it is far
superior in point of transparency and smoothness. This composition, made
with so small a proportion of water as to have it of the consistence of
plastic clay, may be used to form models, busts, basso-relievos, and
similar articles. When made of it, they are suscep
