and other Ceramic or Vitrifiable Materials.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of 53,
Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents
do hereby declare the nature of this Invention a communication to me from abroad
by Charles Joseph Brunetti, Decorator on Porcelain, of 122 Faubourg, St. Martin,
Paris, France, to be as follows :-
--
This invention relates to an improved process of ornamenting articles of glass,
porcelain and other ceramic or vitrifiable materials.
By means of this process results are obtained equal in respect of sharpness and
delicacy in other respects to those obtained by hand decoration.
According to this improved process, the ground of the design to be reproduced is
first printed upon any suitable transfer surface which is capable of being applied upon
the object to be decorated, care being taken that the design be in blank or in reserve
and that the ink or varnish covers all the ground or parts of the surface that are not to
receive the metal which is to constitute the decorative medium. This impression
having been transferred to the article, the latter receives, by dusting or otherwise a
coating of some incombustible material such as asbestos or a silicate and preferably
pulverised chalk in order that when the article is afterwards placed in a muffle, the
material shall not become incorporated therewith. The ground having been thus
protected, the portions reserved for the design only remain exposed upon which the
gold or other vitrifiable metal may be applied either with a brush or by immersion or
other means. The article is then fired and after removing the protective coating which
surrounds the design there remains only the gold or other metal in sharp and clearly
defined outlines upon the porcelain or other surface to be decorated.

I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of 53,
Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents,
do hereby declare the nature of this Invention (a communication to me from abroad
by Charles Joseph Brunetti, Decorator on Porcelain, of 122 Faubourg St. Martin,
Paris, France, 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 an improved process of decorating or ornamenting articles
of glass, porcelain, and other ceramic or vitrifiable materials.
By means of this process, results are obtained equal in respect of sharpness and
delicacy to those obtained by hand decoration.
According to this improved process, the ground of the design to be reproduced is
first printed upon any suitable transfer surface which is capable of being applied upon
the object to be decorated, care being taken that the design be in blank or in reserve
and that the ink or varnish covers all the ground or parts of the surface that are not
to receive the metal which is to constitute the decorative medium. This impression
having been transferred to the article, a coating of some incombustible material such
as asbestos or a silicate and preferably pulverised chalk, is then applied by dusting or
otherwise to the ground which has been printed on as above mentioned, so that when
the article is afterwards placed in a muffle the material shall not become incorporated
therewith.
The ground having been thus protected, there remains exposed only the portions
reserved for the design upon which the gold or other vitrifiable metal is then applied
either with a brush or by dabbing or by immersion or other means.
The article is then fired and after removing the protective coating from the ground
which surrounds the design there remains only the gold or other metal in sharp and
clearly defined outlines upon the porcelain or other surface to be decorated.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is-
The herein described process of decorating articles of glass, porcelain, and other
ceramic or vitrifiable materials, which consists in first transferring an impression of
the ground of the design on to the article, the design being in blank, then applying

page_text: to the ground a layer of incombustible material and afterwards applying the gold,
silver, or other vitrifiable metal serving as the decorative medium upon the exposed
parts of the design, either with a brush, by immersion or other means, and finally firing
the article as specified.
