This mould, which is used in a hot state, opens into
two parts, to allow the insertion of the round, unfinished
bottle, which is placed in it in a very soft state before it is
removed from the end of the iron tube with which it was blown.
The mould is now closed, and the glass is forced against its
sides, by blowing strongly into the bottle.
117. Wooden snuff boxes. Snuff boxes ornamented with devices,
in imitation of carved work or of rose engine turning, are sold
at a price which proves that they are only imitations. The wood,
or horn, out of which they are formed, is softened by long
boiling in water, and whilst in this state it is forced into
moulds of iron, or steel, on which are cut the requisite
patterns, where it remains exposed to great pressure until it is
dry.
118. Horn knife handles and umbrella handles. The property
which horn possesses of becoming soft by the action of water and
of heat, fits it for many useful purposes. It is pressed into
moulds, and becomes embossed with figures in relief, adapted to
the objects to which it is to be applied. If curved, it may be
straightened; or if straight, it may be bent into any forms which
ornament or utility may require; and by the use of the mould
these forms may be multiplied in endless variety.
