PROVISIONAL SPECIFICATION.
An Improved Manufacture of Vitreous Material, suitable for Artificial
Marble, Stained Glass, and analogous Objects.
We, FRANÇOIS RAYMOND ROSTAING, Merchant, LOUIS ANTOINE GARCHEY, Merchant,
and NESTOR EMILE GEILLE, Director of Glass Works, all of 23 Boulevard de
Strasbourg, Paris, France, do hereby declare the nature of this invention to be as
follows
Our invention relates to an improved manufacture of vitreous material which we call
ceramic marble.
The process which we employ for this purpose is based on the method of agglomerating
under the action of heat pieces or waste products of glass manufactures of all kinds
and of all colours.
These pieces, after being crushed or broken to any required size, are placed in a
mould of iron, fireclay or plumbago, of square, rectangular or other form, according
to the size of the slabs of ceramic marble to be obtained.
The materials are isolated from the sides of the mould by a coating of silica, talc or
other suitable infusible substance.
The charged moulds are placed in a furnace heated to the required temperature, so
as to produce a rapid but incomplete fusion of the materials, and thus to cement
together the separate particles. As soon as it is observed that this has taken place,
the mould is removed and is then placed into another furnace for re-heating. This
operation being terminated, the ceramic marble is removed from the mould and is
dressed, cut, polished or decorated with vitreous colours heated in a muffle, according
as may be required.
The above described improved manufacture will generally present two distinct
surfaces. The one surface is uniformly smooth, namely that which has been exposed
directly to the fire, and which becomes glazed by the fusion. The other face, namely
that situated at the bottom of the mould, remains rough with projecting portions of
the unmelted material.
These roughnesses afford a ready means for fixing the slabs either directly upon a
plastered wall or upon pannels of cement or plaster.
There may be mixed with the pieces of glass pieces of china, porcelaine, enamel or
other material that will soften and bind together under heat.
For obtaining granite-like or polychromic effects, there are mixed with the
materials portions of pigments of any desired variety of colours, either transparent
or opaque.
If it be desired to reproduce in the artificial marble designs in relief or intaglio,
the mass while still in a plastic condition, is subjected to pressure with dies or plates
having the designs sunk or in relief upon them.
For decorating with enamel, the coloured materials for this can be introduced at
once into or upon the sunk or raised designs immediately after these have been
impressed as above described, and the slabs be then at once reheated in the
furnace.
By our invention we can produce stained glass windows without the use of
leading.
For this purpose we employ moulds with moveable partitions of thin metal arranged
according to the required designs. The pieces of glass having been placed according
to the required colours in the several compartments of the mould, the partitions are
removed, and the mould is placed in the furnace, whereupon the glass in the several-

page_text: divisions in melting will unite so as to form a continuous glass surface having the
desired design.

COMPLETE SPECIFICATION.
An Improved Manufacture of Vitreous Material, suitable for Artificial
Marble, Stained Glass, and analogous Objects.
We, FRANÇOIS RAYMOND ROSTAING, Merchant, LOUIS ANTOINE GARCHEY, Merchant,
and NESTOR EMILE GEILLE, Director of Glass Works, all of 23, Boulevard de
Strasbourg, Paris, France, 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 :—
Our invention relates to an improved manufacture of vitreous material which we
call ceramic marble.
The process which we employ for this purpose is based on the method of agglomerating
under the action of heat, pieces or waste products of glass manufactures of all kinds
and of all colours.
These pieces, after being crushed or broken to any desired size, are placed in a
mould of iron, fireclay or plumbago, of square rectangular or other form, according
to the size of the slabs of ceramic marble to be obtained.
The materials are isolated from the sides of the mould by a coating of silica, tale or
other suitable not easily fusible or infusible substance.
The charged moulds are placed in a furnace heated to the required temperature, so
as to produce a rapid but incomplete fusion of the materials, and thus to cement
together the separate particles. As soon as it is observed that this has taken place,
the mould is removed and is then placed into another furnace for re-heating. This
operation being terminated the ceramic marble is removed from the mould and is
dressed, cut, polished or decorated with vitreous colours heated in a muffle, according
as may be required.
The above described improved manufacture will generally present two distinct
surfaces; the one surface is uniformly smooth, namely that which has been exposed
directly to the fire, and which becomes glazed by the fusion. The other face, namely
that situated at the bottom of the mould, remains rough with projecting portions of
the unmelted material.
These roughnesses afford a ready means for fixing the slabs either directly upon a
plastered wall or upon panels of cement or plaster.
There may be mixed with the pieces of glass pieces of china, porcelaine, enamel or
other material that will soften and bind together under heat.
For obtaining granite-like or polychromic effects, there are mixed with the
materials portions of pigments of any desired variety of colours, either transparent
or opaque.
If it be desired to reproduce, in the artificial marble, designs in relief or intaglio,
the mass while still in a plastic condition, is subjected to pressure with dies or plates
having the designs sunk or in relief upon them."
For decorating with enamel, the coloured materials for this can be introduced at
once into or upon the sunk or raised designs immediately after these have been
impressed as above described, and the slabs be then at once reheated in the furnace,
thus preventing the necessity of subjecting the blocks to a separate operation for
this purpose.
By our invention we can produce stained glass windows without the use of
leading.
For this purpose we employ moulds with moveable partitions of thin metal arranged

page_text: according to the required designs. The pieces of glass having been placed according
to the required colours in the several compartments of the mould, the partitions are
removed and the mould is placed in the furnace, whereupon the glass in the several
divisions in melting will unite so as to form a continuous glass surface having the
desired design.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The process for producing agglomerated vitreous material suitable for artificial
marble and the like, consisting in subjecting fragments of glass of all kinds with or
without admixture of other material, to a rapid but incomplete fusion so as to
agglomerate them together, the fragments being for this purpose placed in a mould
which is first introduced into a melting furnace, and then into a reheating furnace,
substantially as described.
2. A new manufacture of plates slabs or blocks of vitreous material or artificial
marble produced by treating fragments of glass, with or without other material in the
manner set forth in the preceding claim, the slabs plates or blocks being either plain
or stamped with designs in relief or intaglio or ornamented with enamel, or moulded
into ornamental shapes, such as cornices, statuettes, and the like substantially as
described.
