PROVISIONAL SPECIFICATION.
An Improved Material for Covering or Decorating Walls and the
like, and the Method of Producing the same.
I, NICHOLAS RIGBY of 27 Pole Street, Preston, in the County of Lancaster,
Painter, do hereby declare the nature of this invention to be as follows:-
My improved material for covering or decorating walls and the like consists of a
compound in approximately equal parts of cement, plaster of Paris, white lead, and
finely powdered glass mixed together in water with colouring matter added as
required. This compound is spread upon a sheet of (preferably polished) glass
with a brush and whilst the already laid on material is still moist successive coats
are laid on until the desired thickness is attained when it is allowed to dry. The
smooth side of the material or that side which was against the glass is then soaked
with linseed oil and varnish (mixed) which is allowed to drain off and so leave the
surface hard and smooth. The improved material may be cut into squares or other
forms and laid on to a wall or other surface by any of the usual methods and it may
be so colored as to be an imitation of marble, tiles, polished stone, and the like.

An Improved Material for Covering or Decorating Walls and the
like, and the Method of Producing the same.
I, NICHOLAS RIGBY, of 27, Pole Street, Preston, in the County of Lancaster,
Painter, 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 :—
My improved material for covering or decorating walls and the like consists of a
compound in approximately equal parts of cement, plaster of Paris, white lead, and
finely powdered glass mixed together in water with coloring matter added as
required. This compound is spread upon a sheet of (preferably polished) glass
with a brush and whilst the already laid on material is still moist successive coats
are laid on until the desired thickness is attained when it is allowed to dry. The
smooth side of the material-or that side which was against the glass-is then
soaked with linseed oil and varnish (mixed) which is allowed to drain off and so
leave the surface hard and smooth. The improved material may be cut into squares
or other forms and laid on to a wall or other surface by any of the usual methods
and it may be so colored as to be an imitation of marble, tiles, polished stone, and
the like.
"
I find in practice that in addition to plaster of Paris other similar substances such
answer the purpose of my
as Parian cement and "Robinson's white cement
invention equally well whether used separately or in combination with each other."
Whilst the compound is still upon the plate glass-or other equivalently smooth
surface I find it desirable to back up the said compound with some more elastic
or less brittle substance to counteract or obviate the liability to fracture of the

page_text: facing compound. Such a backing up material may be composed of cement mixed
in water with wood pulp or paper pulp.
When dry the smooth side of the improved material may be soaked in varnish-
that is to say without the admixture of linseed oil as hereinbefore mentioned-and
when the varnish becomes dry the polishing operation may be effected by rubbing
with cloths.
The surface or smooth side of the improved material receives its smoothness in
the first instance from the surface upon which it is cast or laid the process therefore
being "self-facing" thus obviating the necessity of grinding and thereby saving
time and producing a better surface or face than by the grinding process.
Moreover the various tints colours or tones-starting with a white basis-may be
regulated so as to give a variety of pleasing effects.

e-purpose of
The finely powdered glass herein before mentioned-is-used-for-the-
imparting increased hardness to the improved material but is not actually an
essential in the production thereof.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is: :-
The improved material for covering or decorating walls and the like, and the
method of producing the same substantially as described.
Dated this 23rd day of January 1894.
