STAMPING TOILET SOAP.
on an upper floor, run long wooden shoots,
and down these the liquid soap is drawn off.
At this stage some soaps are scented, some
coloured, and some receive ingredients which
result in cheapening them. But for most
there is a direct road from the boiling pan
to the cooling frame. 1 hese frames are
about five feet high, and hold about fifteen
hundredweight of soap. They are made of
iron, the sides and ends being clamped to-
gether so that they can be removed, leaving
a solid block of soap ready
for cutting up. The cooling
process naturally depends
on the weather, but it
generally occupies four or
five days. While the soap
is standing in the frames
slight pressure is applied
to it from the top to
solidify it completely.
In a large factory, such
as that of Messrs. Lever
Brothers at Port Sunlight,
the cooling room is an
interesting and busy scene.
When the frames have
been removed from the
solid soap, the workman
sets about the cutting up
of the great blocks. For
this purpose he employs a machine
consisting of an upright frame which
is furnished with transverse wires, and
these by means of a wheel and chain
are drawn through the soap, cutting it
up into slabs of the thickness desired.
The slabs, creamy and beautiful, like
new cheeses, are hurried along to an-
other machine, where they are cut into
bars. The mechanism which performs
this operation is a lever frame on which
are strung vertical wires that are drawn
through the soap. The bars are after-
wards piled in such a manner as to
let the air circulate freely about them.
A day or two of this exposure fits
them for packing and for use.
Here we may take leave of the
laundry soap, or rather of those soaps
that are put on the market without the
artistic finish we associate with the
usual toilet soap. When the further
processes applied to the superior kinds of
soaps are to be gone through the bars are
conveyed to another department. Here,
first of all, the soap is thoroughly dried.
This is done by passing the bars into a
machine which cuts them up into ribbons,
and carries these ribbons along through hot
air till the moisture is removed. At this
stage the soap feels to the hand not unlike
wood shavings.
Scenting and colouring are the next opera.
