PROVISIONAL SPECIFICATION.
Improvements in Decorating Transparent and other Surfaces.
I FERDINAND HENRY WARLICH of 19 Station Road South Norwood do
hereby declare the nature of this invention to be as follows:-
:-
The production of transparent pictures or designs of any desired subject or shape
in carbon tissue or gelatine pigments on surfaces composed wholly or in part of
compounds of pyroxyline such as celluloid xylordine and other similar substances
for decorating church and other windows glass doors menu cards lantern slides,
ladies fans fire screens lamp shades and for advertising purposes etc.
For the above purpose I take a sheet of sensitized carbon tissue or gelatine
pigment & after exposing it to light under a negative or positive plate of the
subject required I plunge it into cold water for a very short space of time, and lay
it on the celluloid film or any other compound of pyroxyline and squegee the
surfaces together being careful to exclude the air. After this has been done and
the surface has become partially dry which will be in about five minutes I immerse
the united films in a tray filled with water the temperature of which may be
from 90 to 115 Fahr. In the course of a minute the paper upon which the
pigmented tissue was supported may be gently drawn away and the film which will
be left with most of the colored compound adhering to it must be gently washed
the water being thrown gently with the hand over it, the picture or design will
gradually appear as the excess of color is dissolved away.
If the process has been correctly performed the picture will appear with all its
details to perfection.
The next process is to remove it to the alum bath of the strength of one part
of alum to 30 parts of water and allowed to remain until every particle of yellow
color caused by the excess of chromic salt in the pigment tissue has entirely dis-
appeared the alum solution having a strong solvent action upon the chromic salt
will soon accomplish this the picture or design is then washed in clear cold water
until all trace of alum is removed and dried in any convenient manner.
When perfectly dry it is ready for use, or it can be colored with transparent
colors mixed with gold size and varnished.
Dated this 8th day of January 1891.

Engineer do hereby declare the nature of this invention and in what manner the

and squegee the surfaces together being careful to exclude air. After this has been
done and the surface has become partially dry which will be in about 5 minutes I
immerse the united films in a tray or dish filled with water the temperature of
which may be from 90 to 115 Fahr.
In the course of a minute or two the paper upon which the pigmented tissue was
supported may be gently drawn away and the film which will be left with most of
the colored compound adhering to it must be gently washed the water being
thrown gently with the hand over it the picture or design will gradually appear as
the excess of color is washed away.
If the process has been correctly performed the picture or design will appear
with all its details to perfection.
The next process is to remove it to the alum bath of the strength of one part of
alum to 30 parts of water and allowed to remain until every particle of yellow
color caused by the excess of chromic salt in the pigment tissue has entirely dis-
appeared, the alum solution having a strong solvent action upon the chromic salt,
will soon accomplish this, the picture or design is then washed in clear cold water
until all trace of alum is removed and dried in any convenient manner.
When perfectly dry it is ready for use, or it can be colored with transparent
colors mixed with gold size, turpentine and varnished if required.
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 :
1st. The production of pictures or designs in carbon tissue or colored gelatine
pigments on surfaces composed wholly or in part of compounds of pyroxyline such
as celluloid xylordine and other similar substances.
2nd. The painting in oil or other colors on carbon tissue or colored gelatine
pigment having as a base surfaces composed wholly or in part of pyroxyline such
as celluloid xylordine and other similar substances.
Dated this 2nd day of October 1891.
