IMPROVEMENTS DECORATING GLASS
Year: 1884

page_text: I, EDWIN LLOYD of George Street, Euston Road in the County of Middlesex,
do hereby declare the nature of my Invention for
" IMPROVEMENTS
DECORATING GLASS" to be as follows:-
IN
This Invention relates to improvements in decorating smooth or polished glass
by painting, printing, etching, or engraving a design or ornamentation on the back
surface thereof, and then coating such design or ornamentation with a protecting
surface and with a material to produce a ground or backing for such design or
ornamentation.
I take a sheet of plate or other glass polished on both sides and I paint, print,
etch or engrave the intended design or ornamentation on the back thereof, or I
produce the design by any combination of two or more such processes, I then coat
the design with a suitable protecting varnish and when the same is dry I coat the
whole back surface of the glass including the design or ornamentation with silver
or gold leaf, or otherwise silver or gild the same by any of the known processes, 80
as to produce a mirror like brilliant silver or gold surface on all parts of the sheet
of glass except that covered by the painted or otherwise coloured design. I then
coat the silvered back with varnish or other protecting medium. The coating of
varnish applied to protect the design before the silvering process should be such as
will not be attacked by the acids or other chemicals employed in the said silvering
process.

do hereby declare the nature of my Invention for "IMPROVEMENTS IN DECORATING
GLASS 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 improvements in decorating smooth or polished glass
by painting, printing, etching or engraving a design or ornamentation on the back
surface thereof, and then coating such design or ornamentation with a protecting
medium and with a material to produce a ground or backing for such design or
ornamentation.
I take a sheet of plate or other glass, polished on both sides and I paint, print,
etch or engrave the intended design or ornamentation on the back thereof, or I
produce the design by any combination of two or more such processes, I then
coat the design with a suitable protecting varnish, such as that known as trans-
parent mastic varnish for example, and when the same is dry I coat the whole
back surface of the glass, including the design or ornamentation, with silver or
gold leaf, or otherwise silver or gild the same by any of the known processes, so as
to produce a mirror-like brilliant silver or gold surface on all parts of the sheet of
glass, except that covered by the painted or otherwise coloured design. I then
coat the silvered or gilded back with varnish, thick red-lead paint or other
protecting medium or backing. The coating of transparent varnish applied to
protect the design before the silvering process should be such as will not be
attacked by the acids or other chemicals employed in the said silvering or gilding
process, and I have found that the varnish known as "mastic" varnish is suitable
for the purpose but otl er kinds may be employed according to circumstances.
I am aware that it is not new to decorate or ornament smooth or polished glass
by painting, printing, etching or engraving on the back thereof, or to silver or gild
the back surface of such glass, or to apply protecting media to the back surfaces of
such decoration or ornamentation, or of the silvering or gilding but beretofore, so
far as I am aware such processes have never before been used together to produce
a decorative or ornamental effect on smooth or polished glass.
Having now particularly descriled and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I-claim is
The process of decorating smooth or polished glass by painting, printing, etching
or engraving a design or ornamentation on the back surface thereof; coating the
said design or ornamentation with protecting varnish; silvering or gilding the
back of the glass and the 'design or ornan.entation thereon, and finally coating
the silvered or gilded back with varnish, red-lead paint or other protecting medium
or backing as herein before described.
