PRODUCING DESIGNS OR PATTERNS ON GLASS, GLAZED AND ENAMELLED
SURFACES
"
PROVISIONAL SPECIFICATION left by the said David Reich at the Office
of the Commissioners of Patents on the 8th January 1883.
DAVID REICH of Berlin, doing business under the firm of S. Reich & Co.,
"AN
IMPROVED METHOD OR PROCESS OF PRODUCING DESIGNS OR PATTERNS ON GLASS,
GLAZED AND ENAMELLED SURFACES
"
This Invention relates to an improved method or process of producing designs,
on glass, glazed or enamelled surfaces.
In carrying the said Invention into practice, I proceed as follows that is to
say-I first paint or print the designs, according to one or other of the ordinary
methods, upon the surface of the article; the material which I employ being such
as will resist fusion better than the colours usually employed for glass-staining,
so that it will not unite with the object to be ornamented at that degree of heat
which is required when colours are to be burnt in upon glass or enamel ware.
For example chalk, magnesia, or the like will suit for the purpose.
When the design has thus been laid on, I cover the whole object with a suitable
glass-staining paint, which I burn into the same.
During the firing process, only the glass-staining paint last put on will unite
with the article which is to be ornamented, while the designs originally laid on
will remain unfused, and can, for this reason, be readily removed. The design or
pattern will then shew in the original colour of the article under treatment upon a
ground having the colour of the paste last burnt in..
If the designs are intended to be transparent upon articles having a dull ground,
as for instance, on glass globes for lamps, I cover the transparent glass surface with
the pattern, and then lay on a whitish coloured paste over the whole. After
burning in the latter and removing the pattern which has meanwhile withstood
fusion, the design will appear transparent upon a dull ground.
This process can be carried out not only upon glass ware, but also upon glazed
and enamelled surfaces.

the said David Reich in the Great Seal Patent Office on the 27th June

DAVID REICH, of Berlin, doing business under the firm of S. Reich and Co. "AN
IMPROVED METHOD OR PROCESS OF PRODUCING DESIGNS OR PATTERNS ON GLASS,
GLAZED AND ENAMELLED SURFACES.
This invention relates to an improved method or process of producing designs
on glass or glazed or enamelled surfaces
In carrying the said invention into practice I proceed as follows, that is to say :——
I first paint or print the designs, according to one or other of the ordinary methods,
upon the surface of the article. The material which I employ being such as will
resist fusion better than the colours usually employed for glass-staining, so that it
will not unite with the object to be ornamented at that degree of heat which is
required when colours are to be burnt in upon glass or cuamel ware. For example,
chalk, magnesia, or the like will suit for the purpose.
When the design has thus been laid on I cover the whole object, with a suitable
glass-staining paint, which I burn into the same."
.
During the firing process only the glass-staining paint last put on will unite
with the article which is to be ornamented, while the designs originally laid on
will remain unfused and can, for this reason, be readily removed The design or
pattern will then show in the original colour of the article under treatment, upon
a ground having the colour of the paste last burnt in
If the designs are intended to be transparent upon articles having a dull ground,
as for instance on glass globes for lamps, I cover the transparent glass surface with
the pattern, and then lay on a whitish coloured pasto over the whole. After
burning in the latter and removing the pattern which has meanwhile withstood
fusion, the design will appear transparent upon a dull ground.
This process can be carried out not only upon glass ware, but also upon glazed
and enamelled surfaces
Having thus fully described my said invention and the manner of performing
the same I wish it understood that I claim
The improved method or process of producing patterns on glass, or glazed or
enamelled surfaces, which method or process consists in covering the parts which
are to form the pattern with a paste which does not fuse at so low a temperature
as glass-staining colours, coating the entire article, including the pattern laid on it,
with a glass-staining colour, burning in the latter, and removing the paste covering
the pattern after the burning in is completed, substantially as described.
In witness whereof I the said David Reich have hereunto set my hand
and seal this Twenty third day of June in the year of our Lord One
thousand eight hundred and eighty three.
