County of Middlesex, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE AND ORNAMENTATION OF ARTICLES OF GLASS AND POTTERY."
Sealed the 21st December 1876, and dated the 31st October 1876.
PROVISIONAL SPECIFICATION left by the said Paul Raoul de Faucheux
d'Humy at the Office of the Commissioners of Patents on the 31st October

PAUL RAOUL DE FAUCHEUX D'HUMY, of Oxford Street, in the County of
Middlesex. "IMPROVEMENTS IN THE MANUFACTURE AND ORNAMENTATION OF
ARTICLES OF GLASS AND POTTERY."
The Invention has for its object improvements in the manufacture and orna-
mentation of articles of glass and pottery, whereby metal used in their ornamentation
is more intimately combined therewith than heretofore, and novel ornamental.
effects obtained. For this purpose instead of first completely forming the articles
of glass and pottery, and firing and glazing the latter, and then applying the
metal thereto for ornamentation and again submitting the articles to heat as here-
tofore, I according to my Invention when treating glass apply the metal to a crude
mass or tube of glass, and afterwards proceed by the aid of heat to shape the same
in the manner well understood.
In applying my Invention to pottery I apply the metal thereto either before the
first firing thereof or after it is in the state of "biscuit" and before the glaze is
applied thereto, or I apply the metal thereto when the pottery is glazed, and apply
another coating of glaze over the metal and then submit the articles to an intense
heat.
The following are examples of the method I adopt in carrying my Invention
into effect:-I take gold or other leaf, and when applying it to glass I according to
one process take a cylinder of glass, and by breathing thereon make the outside
thereof slightly moist, and I wrap around such moist cylinder by rolling or other-
wise a coating of gold or other leaf; I then apply an intense heat to such metal
coated cylinder, and thereby cause the metal to be intimately united to the glass,
after which I pass such cylinder into the interior of another closely fitting glass
cylinder, and aided by heat draw down the ends of the latter, closing one end and
'

page_text: leaving the other open; I then submit the compound cylinders to the action of
heat, which unites the two together with the metal embedded between them; I
then elongate the combined cylinder, and thereby cause the metal to become divided
into small particles, leaving spaces of clear glass between the particles of metal, and
I then proceed to blow or shape the cylinder to any desired form in the usual way.
Or I dispense with the exterior cylinder, and after applying a coating of metal
thereto, as before described, I submit it to intense heat until the metal has become
intimately connected with the glass, after which I proceed to elongate the glass
and to blow or shape the same in the usual manner. The metal may however be
applied to the tube or crude glass by painting an amalgam thereon, after which the
glass is submitted to intense heat to secure the intimate connection of the metal and
glass with each other, and the required article formed in the usual way. Or I take
a mass of glass from the furnace, and while hot roll it on leaf metal or in powdered
metal, and then treat it in the manner before mentioned. If however it be desired
to coat the inside of a hollow article with metal, I either apply the metal thereto
when the article is partially formed and either in a cold or a hot state, or I take the
crude glass and blow into the interior thereof powdered metal, and then treat the
glass in the manner before mentioned. When however it is desired to apply a
thick continuous coating of metal to either the inside or outside of the articles,
whether of pottery or glass, I first coat the articles with a thin coating of metal, as
above described, and then submit the same to 'a bath, and deposit thereon by the
electro process a coating of any desired thickness, after which the same may be
burnished and engraved in the manner well understood.
If desired the metal in the state of powder or leaf may be applied to the moulds
in which the articles cither of glass or pottery are formed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Paul Raoul de Faucheux d'Humy in the Great Seal Patent Office on
the 30th April 1877.
PAUL RAOUL DE FAUCHEUX D'HUMY, of Oxford Street, in, the County of
Middlesex. "IMPROVEMENTS IN THE MANUFACTURE AND ORNAMENTATION OF
ARTICLES OF GLASS AND POTTERY."
The Invention has for its object improvements in the manufacture and orna-
mentation of articles of glass and pottery, whereby metal used in their ornamentation
is more intimately combined therewith than heretofore, and novel ornamental
effects obtained. For this purpose instead of first completely forming the articles
of glass and pottery, and firing and glazing the latter, and then applying the metal
thereto for ornamentation and again submitting the articles to heat as heretofore, I
according to my Invention when treating glass apply the metal to a crude mass or
tube of glass, and afterwards proceed by the aid of heat to shape the same in the
manner well understood.
In applying my Invention to pottery I apply the metal thereto either before the
first firing thereof or after it is in the state of "biscuit," and before the glaze is
applied thereto, or I apply the metal thereto when the pottery has been once glazed,
and apply another coating of glaze thereto over the metal, and then submit the
articles to an intense heat.
The following are examples of the methods I adopt in carrying my Invention
into effect:--I take gold or other leaf, and when applying it to glass I according to
one process take a cylinder of glass, and by breathing thereon make the outside
thereof slightly moist, and I then wrap around such moistened cylinder by rolling
or otherwise a coating of gold or other metallic leaf; I then apply an intense heat
to such metal coated glass cylinder, and thereby cause the metal to be intimately
united to the glass, after which I pass such cylinder into the interior of another

page_text: closely fitting glass cylinder, and aided by heat draw down the ends of the latter,
closing one end and leaving the other end open; I then submit the compound
cylinders to the action of heat which unites the two together with the metal
embedded between them. After this I elongate the combined cylinder and thereby
cause the metal between the two thicknesses of glass to become divided or broken
up into small particles, leaving spaces of clear glass between the particles of metal ;
and I then proceed to blow or shape the cylinder to any desired form in the usual
manner. Or I dispense with the exterior glass cylinder, and after applying a
coating of metal thereto in the manner before described I submit it to intense heat
until the metal has become intimately connected with the glass, after which I
proceed to elongate the glass and to blow or shape the same in the usual manner.
In some cases however I submit the metal coated glass to such a degree of heat as
shall be sufficient to cause the metal to adhere thereto and prevent it being removed
therefrom by handling, but at the same time leaves the metal in such a condition
that it can be removed by a graver or tool; I then by means of a suitable graver or
tool execute any desired designs on the glass by removing the metal therefrom
where desired; I then submit the article to heat, and blow or shape the same to
any desired pattern.
In some cases I first coat the glass with one metal, say silver, and then overlay
the same with another metal, say gold, and proceed in the manner last above
described, by which means on engraving the same the gold is removed at intervals,
leaving the silver visible where the gold is removed. The metal may however be
applied to the tube or crude glass by painting an amalgam thereon, after which the
glass is submitted to intense heat to secure the intimate connection of the metal
and glass with each other, and the required article is then formed in the manner
above mentioned. Or I take a mass of glass from the furnace, and while hot roll it
on leaf metal or in powdered metal, and then treat it in the manner before
mentioned. If however it be desired to coat the inside of a hollow article with
metal, I either apply the metal thereto when the article is partially formed and
either in a cold or hot state, or I take the crude glass and blow into the interior
thereof powdered metal, and then treat the glass in the manner before described.
When however it is desired to apply a thick continuous coating of metal to either
the inside or outside of the articles, whether of pottery or glass, I first coat the
articles with a thin coating of metal and submit them to heat, as above described,
and then submit the same to a bath, and deposit thereon by the electro process a
coating of any desired thickness, after which the same may be burnished and
engraved in the manner well understood.
If desired the metal in the state of powder or leaf may be applied to the moulds
in which the articles either of glass or pottery are formed, by which means the
metal will be applied to the surfaces thereof, and can be intimately connected
thereto by the application of heat.
Having thus described the nature of my said Invention, and the mode in which I
carry the same into effect, I would have it understood that I claim the modes and
processes employed in the manufacture and ornamentation of articles of glass and
pottery, substantially as herein described.
In witness whereof, I, the said Paul Raoul de Faucheux d'Humy, have here-
unto set my hand and seal, this Thirtieth day of April, in the year of our
Lord One thousand eight hundred and seventy-seven.
