Improvements in the Manufacture of Decorative Panels and the like.
A communication from LA SOCIETE METZ ET COUTURIER, of 23, Boulevard de
Strasbourg, Paris, France, Manufacturers.
I, JOHN CLAYTON MEWBURN, of the Firm of J. C. Mewburn & Ellis, of 55
and 56, Chancery Lane, in the County of London, Chartered Patent Agents, do
hereby declare the nature of this invention to be as follows;-
-
Hitherto wall decorations have been produced in the form of panels or tiles in
decorative pottery, or by painting upon the stone or coatings with which the
walls to be decorated are faced.
Panels in pottery can only be obtained in parts or sections of small surface;
they have therefore the inconvenience that they necessitate and present a great
number of joints, which is a great drawback when the decorative subject is of
importance.
On the other hand the position of the decorations when applied directly to the
coatings with which the walls are faced or directly upon these walls, cannot be
changed when once they have been painted, and they should be produced in situ;
further, they cannot be exposed to inclement climatic influences.
By the present invention all these drawbacks are avoided, a new decorative
product being obtained which it is not necessary to produce at the place where
it is to be employed, which is applied in the same way as pottery panels, but
which possesses the very appreciable advantage over these latter that it obviates
joints. These panels may be made of very large dimensions, up to one and two
metres and even more in length.
The improved decorative panels are made in moulds having a bottom of smooth
or even material, well polished, such as a plate of metal or preferably a plate of
glass; this bottom is surrounded by a frame of plaster or other substance, the
height of the frame being equal to the thickness of the panel to be produced.
The panel is made in the following manner-There are applied upon the
botion of the mould the colors which are to form the design of the panel, for
example landscapes, marine views, still life subjects, portraits, or allegorical
groups. These colors, as well for the outlines of the design as for the colored
filling, are applied in such manner as to form as great a thickness as possible.
Further, in order that these colors may unite and combine well with the mass
which is to constitute the panel and form therewith a firm whole, these colors
are prepared with a mineral substance of suitable color mixed with a paste
having the same composition as that of which the body of the panel is composed.
There may be given as an example of the paste the following, which is pro-
duced by admixing carefully

page_text: 2 parts finely powdered magnesite,
2 parts fine sand, or it may be pulverised pottery ware, kaolin or other
analogous material;
part water, and
I part of a solution of magnesium chloride of 25° Beaume.
As before explained, it is this paste, or an analogous one, which is associated
with the mineral pigment to compose the color which serves for the design.
In order that the color may be applied on the bottom of the mould and still be
capable of afterwards separating therefrom, it is advisable to apply a very thin
coating of a greasy body such as vaseline to the bottom of the mould.
Further, for the purpose of rapid execution of the design, a separate 'design
made upon a sheet of paper and applied beneath the transparent body of the
mould, may be taken as a guide.
When the complete design has been executed-upon the bottom of the mould,
there is run into the said mould to fill it, a composition prepared as above
described, of natural color, or it may be colored as desired. When the whole
mass has set, the sides of the mould are removed and the panel is obtained with
a decorative surface, showing the design encrusted in the mass, absolutely. smooth,.
possessing the polish of enamelled pottery and presenting a striking effect.

hereby declare the nature of this invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
Hitherto wall decorations have been produced in the form of panels or tiles in

Panels in pottery can only be obtained in parts or sections of small surface;

further, they cannot be exposed to inclement climatic influences.
By the present invention all these drawbacks, are avoided, a new decorative
product being obtained which it is not necessary to produce at the place where
it is to be employed, which is applied in the same way as pottery panels,, but
which possesses the very appreciable advantage over these latter that it obviates

Having now particularly described and ascertained the nature of the said
invention as communicated to me, and in what manner the same is to be per-
formed I declare that what I claim is:-
The manufacture of decorative panels and the like which consists in first
drawing or producing the desired design in a suitable mineral color or colors
upon the preferably smooth bottom of a mould and in then running into the
mould the paste or composition which is to constitute the body of the panel or
the like, the color or colors, which serve for the design being preferably mixed
with paste of the same or an analogous composition to that which is to form the
body of the panel or the like, all substantially as hereinbefore described.
