ARTIFICIAL MARBLES
Year: 1859

page_text: LETTERS PATENT to Auguste Evaux, of 206, Regent Street, London, for
the Invention of "ARTIFICIAL MARBLES."
Sealed the 31st January 1860, and dated the 12th August 1859.
PROVISIONAL SPECIFICATION left by the said Auguste Evaux at the
Office of the Commissioners of Patents, with his Petition, on the 12th
August 1859.
I, AUGUSTE EVAUX, of 206, Regent Street, London, do hereby declare the
nature of the said Invention for "ARTIFICIAL MARBLES," to be as follows:-
The ordinary stuccos are made with plaster and water containing more or
less gelatine in dissolution. For the frescos the plain area is made of a paste
fabricated with white marble in powder and slack lime in equal proportions.
The different colours used in these cases are employed with water or paste,
and are never well fixed, what provents obtaining an elegant finished smooth
and solid.
I sought for means which would allow in the employment of paste for
frescos, to fix the colours in such a manner as to produce a fine artificial
marble being polished as real marble, and possessing all its qualities. To this
effect I found that the colours mixed with albumine gave me in this application
all the conditions I sought for, and by these means I arrived to obtain the
finest marbles of permanent solidity.
The mineral colours are the only ones which can be employed for that

page_text: purpose; and I have also made a successful application of the white of zink,
of which nobody had yet used for the grounds.
My Invention depends then on the fabrications of artificial marbles by the
new means of fixing the colours obtained by mixing with albumine and the use
of white of ziuk for the grounds.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Auguste Evaux in the Great Seal Patent Office on the
2nd February 1860.
TO ALL TO WHOM THESE PRESENTS (SHALL COME, I, AUGUSTE
EVAUX, of 206, Regent Street, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing (date the Twelfth day of August, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Auguste Evaux, Her special licence that I, the said Auguste Evaux,
any executors, administrators, and assigns, or such others as I, the said
Auguste Evaux, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "ARTIFICIAL
MARBLES," upon the condition (amongst others) that I, the said Auguste
Evaux, by an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Auguste Evaux, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
It is well known that the stuccos in ordinary use are made with plaster and
water with more or less gelatine therein in solution. For frescos the plane
area is made of a paste composed of white marble in powder and slaked lime
in equal proportions. In making these stuccos or frescos, different colors are
employed mixed with water or paste, and are never well fixed in the compo-

page_text: sition, thus rendering it difficult, if not impossible, to obtain a smooth, solid,
and highly polished or finished surface. The object of my Invention is to
obtain in the employment of paste for frescos, means by which the colors used
are fixed, so as to produce a fine artificial marble as capable of being polished
as real marble, and possessing all its qualities. I obtain this by using or
mixing albumen "albumine" with the colors in the preparation of artificial
marbles, the result being that the artificial marbles so composed present a
solid hard surface capable of being highly polished. In the use of colors com-
bined with albumen for making artificial marbles, I confine myself to those
termed mineral, using for the grounds white of zinc, commonly termed "zinc
white."
Having now described the nature of my Invention and the means used for
carrying the same into effect, I have now to state that I have given no
proportions, as they must necessarily vary under different circumstances; but
that I claim as of my discovery,
Firstly, the exclusive use of albumen "albumine" for mixing with mineral
colors in the preparation of artificial marbles.
Secondly, the exclusive use of zinc white for the grounds of artificial
marbles.
In witness whereof, I, the said Auguste Evaux, have hereunto set my
hand and seal, this First day of February, in the year of our Lord
One thousand eight hundred and sixty.
Witness,
