PROVISIONAL SPECIFICATION.
An Improved Method of Decorating Walls and Ceilings, and of
Making them Impervious to Damp and Dirt.
HARRY SMITH 33 Withington Road Whalley Range Manchester Analytical
Chemist do hereby declare the nature of this invention to be as follows:-
My invention consists in the application of pieces of glass plate either plain or
coloured or decorated by some design produced by etching the glass or by stamping
upon it a pattern whilst in the molten condition or by printing a design in a colour
or colours upon it or by other means. These pieces of glass I fix upon the walls or
ceilings by a cement or cements which may be white or coloured in such a way as
to add to the beauty or appearance of the design by their forming a white or
coloured background. I also employ ordinary window or sheet glass with a white
cement or opal glass which I fix upon the walls, or walls and ceilings of rooms such
as those of hospitals or lavatories for the sake of cleanliness or on outside walls for
the purpose of reflecting light into rooms. These glasses when thus fixed can be
easily and thoroughly washed from time to time. I prefer as a rule to use pieces
about 6 inches square but I do not confine myself to this or any other size. These
pieces of glass I affix to damp walls by a waterproof cement composed as follows
or some similar composition, for example, I take by preference ordinary elastic
carriage varnish thickened to the proper consistency with white lead or the mixture
may be coloured by any suitable colouring matter or I use for a red coloured
cement, elastic carriage varnish thickened with red lead. The plastered, cemented,
or other walls may be first painted and the cement then applied over the paint or
the cement may be used directly on the surface of the wall. For inside work I
employ cements by preference of the following compositions but I do not confine
myself to any of the cements herein described. I take a thick solution of sodium
silicate (soluble glass) and thicken it to a proper consistency with either china
clay, zinc silicate or other silicate, silica itself, or zinc oxide, apply this to the
wall and fix the glass to it, these soon set and fix the glass plates firmly in
position.
I claim therefore the combination of ordinary or coloured glass or of glass
stamped or printed with a design in colour or colours in combination with cement
for covering walls and ceilings of houses or out door walls or buildings exposed
to rain and frost for the purpose of decoration, reflecting light, and sanitary
purposes.

colours upon it or by other means. These pieces of glass I fix upon walls or ceilings
by a cement or cements which may be white or coloured in such a way as to add to
the beauty or appearance of the design by their forming a white or coloured back-
ground. I also employ ordinary window or sheet glass with a white cement or opal
glass which I fix upon the walls, or walls and ceilings of rooms such as those of

for the purpose of reflecting light into rooms. These glasses when thus fixed can

pieces of glass I affix to damp walls by a waterproof cement composed as follows,
or some similar composition, for example I take by preference ordinary elastic
carriage varnish thickened to the proper consistency with white lead, or I take the
mixture of white lead and linseed oil such as is used by plumbers, or the mixture
may be coloured by any suitable colouring matter or I use for a red coloured
cement elastic carriage varnish thickened with red lead; the plastered cemented
wooden or other walls may be first painted and the cement then applied over the
paint, or it may be used directly on the surface of the wall. For inside work I
employ cements by preference of the following compositions, but I do not confine
myself to any of the cements herein described. 1 take a thick solution of sodium
silicate (soluble glass) and thicken it to a proper consistency with either china clay,
zinc silicate or other silicate, silica itself, or zinc oxide, apply this to the wall or
ceiling and fix the glass to it, this soon sets and fixes the glass plate firmly in
position.
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 :-
The combination of dialed close one of class stemmed
