PROVISIONAL SPECIFICATION.
Improvements relating to the Production of Plaques and similar
Articles from Glass.
1 ERNEST BÖHм of 5 Boxworth Grove, Barnsbury, in the County of
Middlesex, Chemical and Experimental Glass Blower, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to produce plaques and similar articles from
glass.
For carrying out my invention I use a mould the sides of which are provided
with projections or ridges designed to produce the required relief surface. Into
this mould I place the glass when in a plastic condition and blow it until it has
acquired the desired form. Preferably I use a four sided hinged mould in which
I blow a glass vessel comprising four plaques or similar articles joined together by
connecting pieces at their edges and when the glass has set in the mould I take it
out and after annealing, separate the plaques or similar articles by cutting the
connecting pieces and by grinding.
When blown from clear or opaque glass the plaque or similar article may be
painted internally or externally to give it a natural appearance, the paint being
subsequently burnt into the glass in the ordinary way. Articles so produced are
cheap in first cost and are novel and artistic in appearance.
Sometimes I mould the plaque or similar article with a flange or beading around
its outer edges in imitation of a picture frame and sometimes with a plain flat
flange by means of which the finished plaque may be secured by suitable cement
or other adhesive to a plain sheet of glass say a window pane, so that the plaque or
other article is visible inside or outside the window. In the latter case I paint the
plaque on its interior surface so that when secured to the window pane &c., the
paint is hermetically sealed and consequently cannot be affected by atmospheric
influences.

Improvements relating to the Production of Plaques and similar
Articles from Glass.
1, ERNEST BÖнм, of 5 Boxworth Grove, Barnsbury, in the County of
Middlesex, Chemical and Experimental Glass Blower, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of this invention is to produce plaques and similar articles from
glass.
For carrying out my invention I use a mould the sides of which are provided
with indentations projections or ridges designed to produce the required relief

page_text: surface. Into the mould I place glass when in a plastic condition and blow it
until it has acquired the desired form. Preferably I use a four sided hinged mould
in which I blow a glass vessel each side of which forms a plaque or similar article.
When the glass has set in the mould I take it out, and after annealing I separate
the plaques or similar articles by cutting the vessel into four separate plates each
of which forms a plaque or similar article which are then finished off by grinding
the rough edges.
When blown either from clear or from opaque glass the plaque or similar article
may be painted internally or externally to give it a natural appearance, the paint
being subsequently burnt into the glass in the ordinary way. Articles so produced
are cheap in first cost and are novel and artistic in appearance.
Sometimes I mould the plaque or similar article with a flange or beading around
its outer edges in imitation of a picture frame, and sometimes with a plain flat
flange by means of which the finished plaque may be secured by suitable cement
or other adhesive to a plain sheet of glass, say a window pane, so that the plaque or
other article is visible inside or outside the window, that is to say, it is visible from
both sides of the sheet of glass to which it is attached. In the latter case I paint
the plaque on its interior surface, so that when secured to the window pane or other
sheet of glass the paint is hermetically sealed and consequently cannot be affected
by atmospheric influences.
It is obvious that instead of blowing the glass in the mould, I may use a male
and a female mould and either cast or press the plastic glass between them so as to
produce a glass plaque or similar article as above described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is;'
1. A plaque or similar article made of glass substantially as described.
2. A plaque or similar article made of glass painted with colours and the paint
burnt into the glass substantially as described.
