_Adhesive Cements._--Mixtures of animal, vegetable and mineral
substances are employed in great variety in the arts for making
joints, mending broken china and other objects, &c. A strong cement
for alabaster and marble, which sets in a day, may be prepared by
mixing 12 parts of Portland cement, 8 of fine sand and 1 of infusorial
earth, and making them into a thick paste with silicate of soda; the
object to be cemented need not be heated. For stone, marble, and
earthenware a strong cement, insoluble in water, can be made as
follows:--skimmed-milk cheese is boiled in water till of a gluey
consistency, washed, kneaded well in cold water, and incorporated
with quicklime; the composition is warmed for use. A similar cement
is a mixture of dried fresh curd with 1/10th of its weight of
quicklime and a little camphor; it is made into a paste with water
when employed. A cement for Derbyshire spar and china, &c., is
composed of 7 parts of rosin and 1 of wax, with a little plaster of
Paris; a small quantity only should be applied to the surfaces to be
united, for, as a general rule, the thinner the stratum of a cement,
the more powerful its action. Quicklime mixed with white of egg,
hardened Canada balsam, and thick copal or mastic varnish are also
useful for cementing broken china, which should be warmed before their
application. For small articles, shellac dissolved in spirits of wine
is a very convenient cement. Cements such as marine glue are solutions
of shellac, india-rubber or asphaltum in benzene or naphtha. For use
with wood which is exposed to moisture, as in the case of wooden
cisterns, a mixture may be made of 4 parts of linseed oil boiled with
litharge, and 8 parts of melted glue; other strong cements for the
same
