IMPROVEMENTS IN IMPRINTING AND VITRIFYING DESIGNS ON GLASS
Year: 1884

page_text: We WILLIAM PUZEY of 122 London Wall & ADOLF GERKEN of 5 Aldermanbury
Postern in the city of London Merchant Agent do hereby declare the nature of
our Invention for IMPROVEMENTS IN IMPRINTING AND VITRIFYING DESIGNS ON
GLASS to be as follows:-
In order to carry out our Invention we mix a fairly ground Enamel or other
Vitrifiable pigment with a Varnish or with such a medium as glycerine or Syrup
and using such a mixture as a printing ink we stamp words figures or designs
upon the glass to be decorated, by means of an India rubber stamp We afterwards
fire at such a temperature as to fuse or partially fuse the Enamel or vitrifyable
pigment, and not to fuse the glass.
We frequently find it advantageous to Stamp with the vehicle or medium
without the addition of the Enamel or vitrifiable pigment, after which we dust
on the finely powdered Enamel or vitrifyable pigment with a soft material such
as cotton wool or its equivalent & wipe off such excess as does not adhere to
the printed impressions after which we fire as before The mode of dusting
a powdered pigment upon an adhesive impression is well understood by Printers
or Lithographers.

page_text: COMPLETE SPECIFICATION.
We, William PUZEY, Merchant, of 122 London Wall in the City of London,
and ADOLF GERKEN, Agent, of 5 Aldermanbury Postern, in the City of London,
do hereby declare the nature of our Invention for IMPROVEMENTS IN IMPRINTING
AND VITRIFYING DESIGNS ON GLASS, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
In order to carry out our invention we mix a finely ground enamel, or other
vitrifiable pigment with a varnish or with such a medium as glycerine or syrup,
and using such a mixture as a printing ink, we stamp or print words, figures, or
designs upon the glass to be decorated, by means of an India Rubber Stamp. We
afterwards fire at such a temperature as to fuse or partially fuse the enamel, or
vitrifyable piginent, and not to fuse the glass.
We frequently find it advantageous to stamp with the vehicle or medium
.without the addition of the enamel or vitrifiable pigment, after which we dust
on the finely powdered enamel or vitrifyable pigment with a soft material, such
as cotton wool or its equivalent, and wipe off such excess as does not adhere to
the printed impressions, after which we fire as before. The mode of dusting
a powdered pigment upon an adhesive impression, is well understood by printers
or lithographers.
When we print with variously coloured enamels or vitrifiable pigments in
succession, it is sometimes convenient to fire those first applied, before printing
the remainder on the glass.
We need say nothing as to the means of securing proper register between the
various tints or impressions, as we adopt means well known to printers or
stampers.
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
I. Printing on Glass with a vitrifiable pigment and firing the same substantially
as described.
II. Printing on Glass with an adhesive medium, dusting with a vitrifiable
pigment, and firing the same, substantially as described.
