PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Soaps and Cleansing
Compositions.
I ROBERT STONE, of 8 Talbot Court, in the City of London, Engineer, do hereby
declare the nature of my said invention to be as follows :-
The object of my invention is to manufacture soap from slate, or slate refuse,
marble or marble chippings, or any rock, or other mineral substances in what may be
called an immature state, prior to their development into harder substances..
These minerals are ground to a fine powder, and mixed with tallow, soap, oils,
greasy substances, or liquids, in proper proportions, and formed into bars or tablets
of any convenient size and shape, for sale.
I sometimes use the aforesaid mineral substances without the admixture of tallow,
soap, greasy substances, or other emollients, and form the same into cakes or bars as
aforesaid.
By my invention 1 am enabled to manufacture a very cheap substitute for the
more ordinary, expensive soaps; my improved soap being suitable for all purposes
for which soap is used.

Improvements in the Manufacture of Soaps and Cleansing
Compositions.
I ROBERT STONE of 8 Talbot Court in the City of London Engineer, do hereby
declare the nature of my said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement
The object of my invention is to manufacture soap from slate or slate refuse,
marble, shale, or any rock, or other mineral substances, in what may be called an
immature state, or which will, when ground. yield a powder of a fine silky nature.
These minerals separately or any mixture of the same are ground to a fine powder
and mixed with tallow, soap, oils, greasy substances or liquids in the proportion of
from 25 to 50 per cent. (more or less) with any one or more of such last mentioned
substances or liquids, and are then formed into bars or tablets of any convenient size
and shape, for sale.
For cleaning purposes I sometimes use any one or any mixture of the aforesaid
mineral substances without the admixture of tallow, soap, greasy substances, or other
emollients.
In some cases I may add from 25 to 50 per cent. (more or less) of Devonshire or
china clay for hardening purposes.
By my Invention I am enabled to manufacture a very cheap substitute for the
more ordinary, expensive, soaps; my improved soap being suitable for all purposes
for which soap is used.
When mixed with oils only it will be useful as a soft or liquid soap for various
purposes.
