declare the nature of our invention for IMPROVEMENTS IN THE MANUFACTURE OF
ARTIFICIAL MARBLES GRANITES, AND THE LIKE to be as follows:-
<
bat,"
We endeavour to imitate as far as practicable the operations of nature in the
production of the various marbles and granites by the hereafter explained means,
that is to say, we roll, run, or beat out a piece of clay, cement, plaster, or other
plastic composition, on a board or slab, into what is technically known as a
of the desired size and thickness to be made, we then allow it to dry atmospherically
or by heat until it cracks or breaks into pieces in consequence of its dryness, or we
break it by gently tapping it in various places as in our judgment will the best
tend to form the veins, &c, as in the marble we purpose imitating; as the pieces lie
in the possition formed by such fracture or naturally by dryness, we pour between
or into such fractures a slip composed of such coloured clay, minerals, inetilic and
other colors and water, as will form the shade colour and veins &c of the marble it
is intended to imitate, and then dry as before; and so again repeat the fracturing
process and filling in of colour until in the opinion of the operator the desired
imitation or effect is attained. In the imitation of certain marbles we use figures
of shells, bones, fossils, &c produced from moulds. We may remark that we either
make the articles with the veins, &c, passing entirely through the bulk thereof, or
use such bats as a face or veneer, backing it in a mould or moulds with clay or
other plastic material as suits the purpose in view. The granites are produced of
the scraps made in the fore part of the process, by passing them through various
sized riddles, and moulding them as above stated, &c the articles are then Baked or
fired in the well-known usual way, and glazed or not in such firing as may be
deşired, except such articles as are made of plaster, cement, or other plastic
material.

SHAW, of 6, Perry Street Dudley Road Wolverhampton, Telegraphist; and EDMUND
SAMUEL SHAW, of 25, High Street, Tunstall, Printer, all in the County of Stafford
do hereby declare the nature of our invention for IMPROVEMENTS IN THE MANU-
FACTURE OF ARTIFICIAL MARBLES GRANITES & THE LIKE and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
We endeavour to imitate as far as practicable the operations of nature in the
production of the various shades veins and conformation of marbles and granites by
the hereafter explained means, that is to say, in the first place we roll run or beat
out a piece of clay cement plaster or other plastic material on a slab or board into
what is technically known as a bat of the desired size and thickness of the article
to be made we then allow it to dry atmosperrically or by artificial heat until it
cracks or breaks into pieces, in consequence of such dryness or we break it by
gently tapping it in various places as in our judgment will best tend to form the
veins &c as in the marble we purpose imitating-as the pieces lie in the position
formed by such fracture or natural dryness we pour between or into such fractures
a slip composed of such coloured clays minerals or other metallic colours, or bodies
as will form the shade colour and veins as before stated and so repeat the fracturing
process and filling-in of colours until in the opinion of the operator the desired
imitation or effect is attained in the imitation of certain marbles we use figure of
shells, bones, fossils, plants, &c &c, produced from moulds, we may remark we
either make the articles with the veins &c passing entirely through the bulk
thereof, or use such bats as a face or veneer backing it in, in a mould with clay or
other plastic material as suits the purpose in view the articles are then baked or
tired in the well known usual way, and glazed or not in such firing as may be
desired, except such articles as are of plaster cement, or such other material the
granites are produced from the scraps by passing them through riddles of various
sized meshes, and moulding and firing as before mentioned.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is performed we declare that what we
claim is
The making of artificial marbles with clay plaster cement or other materials by
causing natural shades veins colours &c by fracturing and filling in the same in the
way and manner herein before set forth.
