Improvements in Enamelling Glass Plates and their Application to
Walls and Ceilings for Decorating or Covering same.
I, NESTOR EMILE GEILLE, Ceramic Enameller, of 211, Rue de l'Intendant,
Molenbeck, Brussels, in the Kingdom of Belgium, do 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:-
This invention relates to a method of enamelling glass plates of all kinds in any
colours and rendering them opaque for the purpose of forming panels, frame-work
and other objects for decorating and lining or covering, and has for its object to
provide a covering or decoration of enamelled glass to be applied to walls and
surfaces of all kinds such as ordinary walls, ceilings panellings, the glass plates
being of all kinds, shapes, dimensions and colours, appropriate to receive a decora-
tive or ornamental covering by previously imparting to them a special enamel,
by which at the same time a rough surface is produced, which imparts, to the
surfaces to be covered, a suitable adhesive quality.
According to this invention plates of broad glass, sheet glass, smooth, uncoloured
or coloured glass, preferably of but slight thickness are coated with enamel upon
any surface and are then placed into a furnace, in which a sufficient temperature
is kept up to cause the enamel to firmly combine with the glass. After thus having
been gradually heated, they are slowly removed from the furnace, in order to prevent
rupture. Clear glass can thus be rendered opaque or semi-opaque in any colours
imitating for example all kinds of marble; in general a cracked glazing or a frosted
glass surface; and can subsequently be covered with various decorative or orna-
mental designs, with the object of rendering them appropriate for the construction
or the coating of ceilings, panellings, walls or other surfaces inside or outside of
buildings. These enamelled glass surfaces are rendered perfectly adhesive to
receive any coating and thus form plates or panels for lining or covering being of
very light weight and yet of great durability.
In order to impart a harmonious aspect to the joints always existing in any
kinds of coverings or linings, which according to this invention are but slightly
noticeable; a framing or sectioning is employed with the enamelled glass plates by
means of which the joints can be concealed or covered. The framing is applied
in the form of evenly assorted edgings or borders of enamelled glass, of glazed
bodies, enamel or porcelain arranged in all colours and serving to still further
increase the artistic appearance of the covering or lining, after having previously
been rendered adhesive upon that side which they are required to cover by applying
the process previously described.
These framings, edgings or borders may be formed in one single piece and may
encase each one of the enamelled glass sheets or panels, or may be composed of
several parts, appropriately fixed one by one according as the lining is arranged.
They may also be continuous, that is to say mouldings, cast or artistically produced

page_text: in any suitable manner thus representing appropriate decorative subjects such as
reses, twisted fingers, arabesques and the like which may be gilt if desired.
This arrangement of framings adherent to the wall to be lined or covered may
also be advantageously employed for fixing or applying to the said wall, glass
sheets or panels enamelled by cold process, and not presenting any rough or
wrinkled adhesive surface, as the framings, edgings or borders which more deeply
enter the coating of the wall to be covered or lined, remain fixed thereto so that
on uniting the various sheets or panels of the covering which are not made other-
wise adhesive they will retain them in their position.
The same arrangement may however, be employed to serve for framing or orna-
menting panel linings of crockery ware, porcelain, terra cotta, pottery or other
analogous substance used at the present time.
The decorative edgeings or borders may be of any dimensions brought into
appropriate proportion as regards length, width and thickness, with the dimensions
of the plate linings or coverings which they are intended to enclose or partition.
They are manufactured according to the process before referred to, of enamelled
glass, plain or decorated and in any colour, arranged separately or soldered, or
glazed during the enamelling process, and thus constitute an important part of
this invention.
By this invention, ne main object of which is to provide sheets of opaque glass
of all colours by enamelling clear or transparent glass, and to provide appropriate
decorations to enhance the decorative appearance of the sheets when being applied
as a covering or lining; in the form of edgings or framings, forming integral part
or being separately employed not only solid, light and bad heat conducting linings
are obtained which efficiently stand all kinds of weather but which moreover owing
to their moderate price may be employed for all kinds of constructions. The process
herein described is applicable indifferently to glass plates of all dimensions, but
is more especially intended to be applied to glass plates of small dimensions, for
which profitable employment is not otherwise easily found, on account of defects
or inadequate sizes.
In the accompanying drawing are shown several devices of panels, edged,
framed or not, also various types of edgings and framings that may be employed.
Fig. 1 is a plan of a panel of enamelled glass, or marble, without edging or
frame constructed according to this invention.
Fig. 2 is a plan of a plain enamelled glass panel with frame formed of the
following different kinds of borders: beaded, oval, vermiculated, striped, and having
their several constituent parts suitably connected.
Fig. 3 shows in section a framed glass panel capable of receiving any appro-
priate shape and size. The framing cemented or otherwise fastened on the panels
may be provided with a projection extending more or less toward the wall, and
which projection serves to secure plain enamelled glass panels in their position
or to simply fix decorative nottery panels or other analogous products.
Fig. 4 is a sectional elevation of a panel with framing fixed thereto by means of
the enamel and forming a single piece ready to be applied as a covering or lining;
the panel or the border may be of glass crockery, porcelain or the like.
Fig. 5 shows part of a framing or large border, to serve as a richer means of
decoration likewise demented by one single operation on to the enamelled glass
panel, which may be either plain or provided with any decoration.
It will be obvious that the forms and arrangements, herein described, according
to which the panels may be framed or not, or made in one single piece or partitioned
or sectioned, may vary indefinitely and may be square, rectangular, oval and so
forth with borders cemented or otherwise united therewith, so as to form the most
manifold decorative objects, without departing from the principle of this invention
since the method of decorating and lining by means of enamelled glass, either
continuous or sectioned, remains always the same.
Having now particularly described and ascertained the nature of my said inven-

page_text: tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. An improved method of enamelling, serving to render glass plates of any
kind, shape, dimension, but more especially broad glass; opaque or semi-opaque
by using any colours, the object being to form such enamelled glass into panels,
framings or any other decorative or ornamental objects and to thus form a par-
ticular kind of bad-heat conducting, waterproof, hygienic and extremely durable
covering or lining material of artistic appearance, suitable for decorating and
covering walls, ceilings, for forming panels of any kind and style, the characteristic
feature being that upon any surface of the plates or of the parts to serve as framings
or border, a layer of hot enamel is placed and the wrong side of which is made
uneven to admit of its adhering to the surface of the wall to be covered; substanti-
ally as described and represented in the drawing.
!
2. A device serving for producing plain (continuous) or sectioned linings or
coverings with or without framings, by means of plates panels and borders obtained
by the process ascertained in the first claim, the joints of which can be concealed
by partition work or framings, by using other panels and frames, presenting separ-
ately or simultaneously a rough adhering surface, or also by using framed panels
made in one enamelled piece; and which said rough surfaced enamelled frames
may be likewise employed as crockery, pottery-ware, linings and the like, sub-
stantially as described and represented in the accompanying drawing.
