COMPLETE SPECIFICATION.
Improvements in Imitation Stained Glass, applicable for Decorating
Windows, Walls, or Ceilings.
I, THEOPHIL PFISTER, of 5, 6 and 7, Lensden Place, Golden Lane, in the County
of London, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to an improved manufacture of imitation stained glass
involving the use of small particles of glass (blind beads) in a novel manner to
produce the desired effects.
According to one method, I take litho glass, or similar decorative paper used
as imitation stained glass and coat it with varnish or other adhesive substance, and
then sprinkle thereon small particles of glass (blind beads) which adhere to the
varnish and produce a sheet that can be handled like a sheet of glass. I brush
off the superfluous particles and then varnish the surfaces of the sheet and when
the varnish is dry 1 place the work between two sheets of glass without fastening
it to either, and secure the edges of the glass together by a beading. Or the work
can be used for decorative purposes without being placed, between glass sheets, or it
may have a
glass sheet on one side only. It may be secured to a window for
example by an adhesive substance, or in any suitable manner.
I sometimes increase the artistic effect by outlining the design with wire, metal
strips, threaded beads, or other suitable materials to improve the appearance, and
in some instances to imitate the leads of ordinary stained glass windows. Any
coloured design can be imitated by using coloured glass particles of the proper
shades applied to both sides of the work, or by particles of different colours on one
side, and particles of a uniform tint on the other side.
For wall and ceiling decorations it is sufficient to apply the particles of glass
to one side of the design.
According to another method I form a design on a sheet of glass by a process
of sandblasting, or by moulding or pressing the sheet when in a semi molten state,
and then I apply the particles of glass in accordance with the colours desired, and
level the surface and then pour varnish or other adhesive substance over it.
After the varnish is dry I may apply a covering sheet of glass to protect the
work, but for some purposes this covering sheet may be omitted.
Another method of decorating a plain sheet of glass, in imitation of what is
known as drapery glass, is as follows. One layer of glass particles is placed over
the sheet of glass in small waves, stripes, circles, or other desired form, and extend-
ing over the whole of the plate, or only over parts thereof, then an even layer of
varnish, gum, or other adhesive material is poured over, and allowed to dry. I
then apply another layer of glass particles and another layer of gum, or varnish,
and so on until the plate is finished. The glass particles need not be laid on the
plate evenly, but rather so as to obtain the desired effects, viz., a rich rainbow
appearance in which all the colours blend, and harmonize, and the different shades

page_text: of colour merge into each other in different parts of the glass. By applying a
greater quantity of material in one place a darker shade may be obtained, and
by a smaller quantity in another place a lighter shade is obtained. The plate
prepared in this way may be left uneven or if desired it can be filled in evenly
with a final layer of particles of a uniform colour, the same being made to adhere
by varnish or the like.
I sometimes outline the design with strips of metal forming a mould and held
in place by means of varnish, gum or other adhesive material. The strips are
removed after the particles have been filled in, and the design is then ready for
leading.
Having now particularly described 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:
1. Imitation stained' glass consisting of litho glass or other decorative paper
covered, with glass. particles of uniform or of varying tints,, held. in, place by an
adhesive substance, and varnished, substantially as described.
2. Imitation stained glass of the kind claimed in tlie preceding claiming clause,
having the design outlined by wire, or by metal strips or otherwise, to increase the
artistic effect, substantially as described.
3. Imitation stained glass consisting of a foundation sheet of glass having a
design formed therein, and particles. of coloured glass caused to adliere thereto
by varnish or the like, and with or without a covering plate, substantially as
described.
4. The herein described method of making drapery glass with superposed layers
of small particles of glass secured on a glass foundation by varnish on the like;
with or without leading, substantially as described!
