France, Gentleman, for the Invention of "IMPROVED APPLICATIONS OF MICA,
PREVIOUSLY COLORED OR METALLIZED, FOR LETTERS AND SIGNS, DECORATING
CHURCHES, ROOMS. SHOPS, FRAMES. AND OTHER ORNAMENTAL AND USEFUL
PURPOSES."A communication from abroad by Mr. Frederic Holthausen,
of Paris, in the Empire of France, Artist.
Sealed the 7th March 1862, and dated the 13th September 1861.
PROVISIONAL SPECIFICATION left by the said Thomas Lamie Murray,
at the Office of the Commissioners of Patents, with his Petition, on the
13th September 1861.
1, THOMAS LAMIE MURRAY, of Paris, in the Empire of France, Gentleman;
do hereby declare the nature of the said Invention for "IMPROVED APPLICATIONS
OP MICA, PREVIOUSLY COLORED OR METALLIZED, FOR LETTERS AND SIGNS, DECORATING
CHURCHES, ROOMS, SHOPS, FRAMES, AND OTHER ORNAMENTAL AND USEFUL PURPOSES,"
to be as follows:-
This Inventionrelates to improved applications of mica, prepared as described
in a previous Patent for which protection was granted to William Clark, and
dated June 1861, No. 1549. I apply it to frames for looking glasses and
pictures,and for decorating the interior and exterior of rooms, shops, & public
buildings,churches, and other purposes requiring gilt or silvered decorations.
The mica, from its inalterable nature, preserves the gilding, silvering, or

page_text: coloring from deterioration, it being covered with the exterior layer of mica.
The articles are further preserved in a state of perfect cleanliness from the
action of all smoke, dust, or from marks caused by insects, which may all be
removed by washing. The surface being always smooth and impervious,
moreover, is capable of resisting the action of corrosive acids, and the metal
or colored surface appears with great brilliancy through the medium of the
mica.
prepare the unica as follows:-It is first cut to the desired thickness
with an ivory or steel knife, and is then coated with a thin layer of isinglass
diluted in water, and the gold or other surface applied, after which it is
allowed to dry. I then take a pattern of copper with the design cut out in it
and place it on the reverse side of the mica and with a small brush remove
any superfluous parts of the metal. I then apply colors, either one or more
times,as considered necessary, and afterwards cont the whole with a solution
of liquid glue diluted in spirits of wine, which I apply for the purpose of
rendering the unica pliable; when this is effected I apply the mica to the
frame or other object, which I coat with glue or other adhesive material,
which is allowed to become comparatively dry. I then apply the mica with
the design on it to the frame or other object, when it is allowed to dry for
about three hours, after which all superfluous parts of the mica are removed,
the application of the mica thus becomes imperceptible. In order to make
the junctions of several pieces of mica imperceptible I first glue them together
with Venetian glue and then apply a hot iron to the parts where the mica is
joined together, when the parts will be completely united.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Lamie Murray in the Great Seal Patent Office on
the 12th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
LAMIE MURRAY, of Furis, in the Empire of France, Gentleman,se.d greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Thomas Lamie Murray, Her special licence that I, the said
Thomas Lamie Murray, my executors, administrators, and assigns, or such
others as I, the said Thomas Lamic Murray, my executors, administrators,

page_text: and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter 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 "IMPROVED APPLICATIONS OF MICA, PREVIOUSLY COLORED OR METAL-
LIZED, FOR LETTERS AND SIGNS, DECORATING CHURCHES, ROOMS, SHOPS, FRAMES
AND OTHER ORNAMENTAL AND USEFUL PURPOSES," a communication to him from
abroad by Mr. Frédéric Holthausen, of Paris, in the Empire of France,
Artist, upon the condition (amongst others) that I, the said Thomas Lamic
Murray, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describo.
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 1, the said Thom as Lamie Murray, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
This Invention relates to improved applications of mica, prepared as described
in a previous Patent for which protection was granted to Mr. Clark, and dated
June 1861,and it consists principally in the application of mica to frames for
looking glasses, pictures, for decorating the interior and exterior of rooms,
shops, public buildings, churches, and other purposes requiring gilt or silvered
decorations.
The mica, from its inalterable nature, preserves the gilding, silvering, or
coloring from deterioration, and from its diaphaneity the articles so treated
will preserve all their brilliancy; they are further preserved in a state of
perfect cleanliness from the action of all smoke, dust, or from marks caused
by insects, which may all be removed by washing. The surface being always
smooth and impervious, moreover, is capable of resisting the action of corrosive
acids, and the metal or colored surface appears with greater brilliancy..
I prepare and apply the mica as follows:-It is first cut to the desired
thickness with an ivory or steel knife and is then coated with a thin layer of
isinglass diluted in water,and the gold or other surface is applied, after which
it is allowed to dry (any article, gilt, silvered, or colored by the known process,
be covered with a thin sheet of mica by glueing). I then take a pattern
of copper with a design cut out on it and place it on the reverse side of the
mica and with a small brush remove any superfluous parts, the required design
nay

page_text: thus remaining on the parts which have not bee brushed.
I then apply
colors, either one or more times, as considered necessary, and afterwards coat
the whole with a solution of liquid gluo diluted in spirits of wino, which I
apply for the purpose of rendering the mica pliable. When this is effected
Lapply the mica to the frame or other object, which I coat with glue or other
adhesive material, which is allowed to become comparatively dry. I then
apply the mica with the design on it to the frame or other object, when it is
allowed to dry for about three hours, after which all superfluous parts are
removed and the external surface of the mica made smooth. In order to make
the junctions of several pieces of mica imperceptible Ifirst glue them together
with Venetian glue and then apply a hot iron to the parts where the mica is
joined together, when the parts will be completely united.
Having thus described the nature of the Invention and the manner in which
the same is to be carried into effect, I wish it to be distinctly understood that
I claim, as being of the Invention, the application of translucent sheets of
mica upon all gilt, silvered, metallized, or colored surfaces, so as to preserve
the brilliancy and color of said surfaces. This smooth, inalterable,diaphanous
coating is further capable of being washed and cleaned.
In witness whereof, I, the said Thomas Lamio Murray, have hereunto
set my hand and seal, this Eighth day of March, in the year of our
Lord One thousand eight hundred and sixty-two.
T. LAMIE MURRAY. (L.S.)
