ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent, Agent. AN IMPROVEMENT IN ORNAMENTING CHINA, GLASS, PORCELAIN,
AND OTHER SIMILAR SURFACES." A communication from abroad by Samuel
Mortimer Adams, of the City, County, and State of New York, United States of
America.
This Invention consists in ornamenting china, glass, porcelain, earthenware, and
other similar surfaces, by printing a design in oil on a layer of vitrifiable color,
mixed with water, and afterward fixing such design by means of heat as will
herein-after be more fully described.
The surface to be ornamented is first coated with a layer of vitrifiable color
mixed with water or with a more adhesive material; then upon this layer is formed
any desired design in oil or other suitable adhesive coloring material.
The design may be applied by any of the well-known methods in common use,
as flexible type, hand tracing, or stencilling.
The oil incorporating with the vitrifiable color at the parts in contact, binds the
design to the surface and the surplus color, or that part of the coating not covered
by the oil design is washed off, thus leaving such design intact upon the surface,
and is ready for firing.

ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent Agent.
"AN IMPROVEMENT IN ORNAMENTING CHINA, GLASS, PORCELAIN,
AND OTHER SIMILAR SURFACES." A communication from abroad by Samuel
Mortimer Adams, of the City, County, and State of New York, United States of
America.
This Invention consists in ornamenting surfaces of china, glass, porcelain, earthen-
ware, and other similar surfaces by printing a design in oil on a layer of vitrifiable
color, mixed with water, and afterward fixing such design by means of heat, as will
be herein-after more fully described.
The surface to be ornamented is first coated with a layer of vitrifiable color
mixed with water, or with a more adhesive material; then upon this layer is
formed any desired design in oil or other suitable adhesive coloring material.
The design may be applied by any of the well-known methods in common use,
as flexible type, hand tracing, or stencilling.
The oil incorporating with the vitrifiable color at the parts in contact, binds the
design to the surface, and the surplus color or that part of the coating not covered
by the oil design is washed off, thus leaving such design intact upon the surface,
and is ready for firing.
Having described the nature of the said Invention and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the herein-
before in part recited Letters Patent is, the method herein described of ornamenting
china, glass, &c., by means of vitrifiable colors mixed with water and applied to the.
object to be decorated in a coating of the desired thickness, a design being then
printed on or otherwise applied to such coated surface with oil, and then such part
of the coating not covered by the said design being brushed off or otherwise
removed, the article so decorated being subsequently subjected to heat for the
purpose of burning on or fixing the design upon the same, substantially as set
forth.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Fifth day of November, in the year of our Lord
One thousand eight hundred and correntez-coven
A. M. CLARK. (L.S.)
