We ALFRED LANDIER and CHARLES HOUDAILLE both' of 24 Rue Paradis
Poissonnière, Paris in the Republic of France, Manufacturers do hereby declare
the nature of this invention to be as follows:-
The object of this invention is the decoration of objects made of glass, crystal,
pottery and other ware, by the interposition, between two layers of material, of
bubbles of air suitably arranged and obtained by means of blowing in special
moulds.
These air bubbles may be made to assume various forms, such as letters, stars, or
diamonds, and these different designs, by reason of their: transparency, produce a
decorative effect analogous to that now produced by cutting or engraving.
In carrying out this invention, moulds are employed in which the design it is
desired to reproduce is cut, preferably in relief.
The workman introduces into the mould the material, and then blows in the
usual way, and the designs, if in relief, are reproduced in intaglio on the surface of
the object.

The object is then taken from the mould, and is coated with a new layer of the
material, the effect of which is to enclose and confine the air in the hollows formed
in the mould. After this, the usual operations, to give the necessary shape, are
performed.
It may be here observed that this second layer is laid on by any known process.
To produce the air bubbles in articles of ceramic ware, the design in intaglio is
produced in any convenient manner, and on the pieces thus prepared a coating of
enamel, more or less translucent is laid on, so as to enclose and confine the air.

page_text: An Improved Mode of Decorating Objects of Glass, Crystal, or
Ceramic Ware.
We ALFRED LANDIER and CHARLES HOUDAILLE both of 24 Rue Paradis
Poissonnière Paris in the Republic of France, Manufacturers 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:-
The object of this invention is the decoration of objects made of glass, crystal,
pottery, and other ware, by the interposition between two layers of material, of
bubbles of air of varying forms and suitably arranged, and this effect is obtained
by means of blowing the object or vessel in a special mould, and covering the so-
formed object with a thin coating of glass or enamel.
These air bubbles may be made to assume various forms, such as letters, stars, or
diamonds, and these different designs, by reason of their transparency, produce a
decorative effect analogous to that now produced by cutting or engraving.
In carrying out this invention, moulds similar to those actually in use at present
are employed, except that instead of having a smooth interior surface, the design it
is desired to reproduce is formed therein preferably in relief.
The accompanying drawing represents one of the moulds, and on which different
designs are indicated in relief; thus, at A are shown stars, at B stars of a different
form with the letters L H in the middle, while at C diamonds are represented.
It will of course be understood that the designs may be varied at will.
The workman introduces into the mould the material, and then blows in the
usual way, and the design, if in relief, is reproduced in intaglio on the surface of the
object.
The object is then taken from the mould, and is coated with a new layer of the
material, the effect of which is to enclose and confine the air in the hollows formed
in the mould. The finishing operations are performed in the ordinary manner.
It may be here observed that this second layer is laid on by any known process.
It is easy to understand that objects can thus be economically obtained, of which
the effect produced is as agreeable to the eye as that obtained by cutting or
engraving.
In the case where this decorative process is applied to objects with linings of
different colors, the operation is carried out in the ordinary manner, but in the
relief moulds, and the third layer which encloses and confines the bubbles of air is
applied as above described.
This process is applicable to all the varieties of manufacture, as well as to all
objects, whatever may be their form.
To produce these air bubbles in articles of ceramic ware, the design in intaglio is
produced in any convenient manner, and on the pieces thus prepared a coating of
enamel, more or less translucent, is laid so as to enclose and confine the air bubbles.
Although it is preferred to form the moulds with the design or pattern in relief, it
is also possible to use moulds with the design in intaglio,

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:—
1. The decoration of glass, crystal, and ceramic ware by means of bubbles of air
confined in hollows formed in the metal or paste by a coating of glass, crystal, or
enamel, substantially as herein shown and described.
2. In the decoration of glass, crystal, and ceramic ware, the use of moulds
presenting, on their interior surfaces, designs or patterns in relief or intaglio, and
intended to produce on the surface of the object, when blown in the mould,
hollows or recesses in which bubbles of air are to be confined, substantially as
described.
