however, perfumed cold, in order
to avoid the loss of scent, 20 per cent. of perfume being evaporated by
the hot process.
The variously named soaps, from the sublime "Sultana" to the ridiculous
"Turtle's Marrow," we cannot of course be expected to notice; the reader
may, however, rest assured that he has lost nothing by their omission.
The receipts given produce only the finest quality of the article
named. Where cheap soaps are required, not much acumen is necessary to
discern that by omitting the expensive perfumes, or lessening the
quantity, the object desired is attained. Still lower qualities of
scented soap are made by using greater proportions of yellow soap, and
employing a very common curd, omitting the oil soap altogether.
SCENTING SOAPS HOT.
In the previous remarks, the methods explained of scenting soap involved
the necessity of melting it. The high temperature of the soap under
these circumstances involves the obvious loss of a great deal of perfume
by evaporation. With very highly scented soaps, and with perfume of an
expensive character, the loss of ottos is too great to be borne in a
commercial sense; hence the adoption of the plan of
SCENTING SOAPS COLD.
This method is exceedingly convenient and economical for scenting small
batches, involving merely mechanical labor, the tools required being
simply an ordinary carpenter's plane, and a good marble mortar, and
lignum vitae pestle.
The woodwork of the plane must be fashioned at each end, so that when
placed over the mortar it remains firm and not easily moved by the
parallel pressure of the soap against its projecting blade.
To commence operations, we take first 7 lbs., 14 lbs., or 21 lbs. of the
bars of the soap that it is intended to perfume. The plane is now laid
upside down across the top of the mortar.
Things being thus arranged, the whole of the soap is to be pushed across
the plane until it is all reduced into fine shavings. Like the French
"Charbonnier," who does not saw the wood, but woods the saw, so it will
be perceived that in this process we do not plane the soap, but that we
soap the plane, the shavings of which fall lightly into the mortar as
quickly as produced.

Soap, as generally received from the maker, is the proper condition for
thus working; but if it has been in stock any time it becomes too hard,
and must have from one to three ounces of distilled water sprinkled in
