PROVISIONAL SPECIFICATION.
Improvements in Transparent Colored Materials for Decorative
Purposes.
I, ALEXANDER MCLEAN, Junior, of 10 Stonor Road, West Kensington in the
County of Middlesex, Mechanical Draughtsman, do hereby declare the nature of
this invention to be as follows:-
The object of this invention is to produce sheets of transparent colored material
with aniline colors suitable for use for decorative purposes.
In carrying out my invention, I take the aniline colors, and mix them with
gelatine, which is then made into thin sheets in the well known manner.
These sheets of colored gelatine I next dip in a bath of oil varnish, and hang
them up to dry.
The gelatine forms a foundation to receive the varnish, and the varnish acts as a
preservative for the colored gelatine.
The sheets thus prepared may be cut up into pieces of various shapes and patterns,
and applied by means of a little adhesive material to the surface to be decorated, a
church window, for example.
The colors are extremely brilliant, and will not be affected by the light, and by
means of pieces from sheets of different colors, many pleasing effects may be produced.
Dated this 14th day of May 1891.

COMPLETE SPECIFICATION.
Improvements in Transparent Colored Materials for Decorative
Purposes.
1, ALEXANDER MCLEAN, Junior, of 10 Stonor Road, West Kensington in the
County of Middlesex, Mechanical Draughtsman, 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 sheets of transparent colored material
with aniline colors, suitable for use for decorative purposes.
In carrying out my invention, I take the stable primary aniline colors, and mix
them with gelatine, which is then made into thin sheets in the well known manner.
These sheets of colored gelatine I next dip in a bath of thin oil varnish, and
hang them up to dry.
The gelatine forms a foundation to receive the varnish, and the varnish acts as a
preservative for the colored gelatine.
The sheets thus prepared may be cut up into pieces of various shapes, and
patterns, and applied by means of a little adhesive material to the surface to be
decorated, a church window, for example.
Figured sheets may be produced by running the gelatine onto figured ground
glass, when part of the gelatine will appear clear and part dull.
Patterns may be produced from sheets of colored geiatine, by cutting out from
the colored gelatine, while still on the glass, and while in a limp state, with a fine
pointed instrument, and by the aid of stencils, certain portions which will constitute
the pattern; running a layer of uncolored gelatine over the same, and finally
treating, as above described, with varnish, after removal from the glass.
When the pattern is desired in two colors (yellow on a red ground, for instance),

page_text: I prepare a sheet of red gelatine, from which I cut the pattern with the pointed
instrument, picking out the cut portions. I then run over this sheet a layer of
yellow gelatine, and when dry, and after removal from the glass, dip the double sheet
in the oil varnish, as before described.
The yellow coating will have practically no effect on the brilliancy of the red,
and the result will be most effective. Other colors may be treated in the same way;
for example, yellow and black, blue and red, or blue and yellow. In the latter case
the combination of the yellow and blue will produce a green ground, while the blue
and red will produce a purple ground.
The oil varnish which I have found best suited for the purposes of my invention
is that manufactured by Mr. James Flack of 264 High Street, Borough, and called.
by him No. 768 Lacquer.
Patterns or other printed matter can be printed upon the gelatine sheets in the
ordinary way, before being dipped in the oil varnish.
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. The material for decorative purposes prepared as herein described.
2. In the preparation of colored material for decorative purposes, the combination
of gelatine, with which the colors are mixed, and thin oil varnish, as set forth.
3. In the preparation of materials for decorative purposes, printing patterns, or
other printed matter, on gelatine sheets which are afterwards coated on both sides
with thin oil varnish, as set forth.
Dated this 15th day of February 1892.
