page_text: LETTERS PATENT to William Lloyd Wise, of 7, Whitehall Place, in the City
of Westminster, for an Invention of "IMPROVED ARTIFICIAL STONE, MARBLE,
OR COMPOSITION, APPLICABLE IN LIEU OF STONE OR MARBLE FOR DECORATIVE
AND OTHER PURPOSES." A communication from abroad by Agapit Brault, of
the Village of Laprairie, in the County of Laprairie, John Watkins and David
Stark Smith, both of the City of Montreal, in the District of Montreal, all in

WILLIAM LLOYD WISE, of 7, Whitehall Place, in the City of Westminster.
"IMPROVED ARTIFICIAL STONE, MARBLE, OR COMPOSITION, APPLICABLE IN LIEU
OF STONE OR MARBLE FOR DCORATIVE AND OTHER PURPOSES." (A communication
from abroad by Agapit Brault, of the Village of Laprairie, in the County of
Laprairie, John Watkins and David Stark Smith, both of the City of Montreal, in
the District of Montreal, all in the Province of Quebec and Dominion of Canada.)
This Invention has reference to a composition to be applied to any of the purposes,
specially decorative, for which stone or marble are now used, and which can be
easily moulded into any shape desired, and made to imitate closely any variety of
the above materials.
This compound may be described as having as a base sulphur, to which is added,
in about the proportion of two to one, any kind of stone or marble, or ivory, bone
dust, etcaetera, ground into granules of any degree of fineness.
In the process of manufacture the sulphur is brought to and kept at about the
melting point, the quantity (i.e., double the amount of the sulphur) of stone or marble
dust used (heated or not, as desired) being gradually incorporated therewith, the
time taken up in the operation and the amount of heat to which the sulphur is
subjected varying according to the quality of the substance mixed therewith, and
that of the material which it is intended to imitate.
Any colouring matter may be mixed with the compound to give the tint
required.
The compound thus made may be run directly from the crucible into the moulds,
or cast into ingots to be melted down as desired.

Having described the nature of the said Invention, and explained the manner of
carrying it into practical effect, as communicated to me as aforesaid, I hereby
declare that what I consider to bo novel and original, and therefore claim as the
Invention secured to me under the Letters Patent hereinbefore in part recited is,―
The manufacture of the improved composition or compound, substantially as
herein before described, and particularly the use in combination of sulphur and
marble dust, in the proportions and for the purposes substantially as described and
set forth.
In witness whereof, I, the said William Lloyd Wise, have to this Specification
set my hand and seal, this Eighteenth day of August, in the year of our
Witness,
