PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Gold, Silver, and Bronze
Paints.
I, WILLIAM CUTLER, of Cannon Works, 75 Constitution Hill, Birmingham, in
the County of Warwick, Manufacturer, do hereby declare the nature of my said
invention to be as follows
The object of my invention is to effect improvements in the manufacture of gold,
silver, and bronze paints, my improved paint not being liable to tarnish by
exposure to the atmosphere or gases.
In carrying out my invention, I dissolve pyroxylin in spirits, ethers essences or
acids, whereby I obtain a suitable form of celluloid in a liquid state. Preferably
I take redistilled acetate of amyl, and dissolve therein pyroxyline, or gun cotton,
so as to render it of the consistence of cream.
I then mix with the liquid celluloid, enough gold, silver, or bronze powder,
to bring it to the consistence of ordinary paint. The paint may then be applied
with a soft brush in the usual manner.
The powder being of greater specific gravity than the celluloid, sinks at once,
and leaves a transparent coating of celluloid, which is water and air proof, and
which therefore acts as a protection against atmospheric, gaseous, climatic, and
other influences; and the brilliance of the paint is preserved.

Improvements in the Manufacture of Gold, Silver, and Bronze
Paints.
1, WILLIAM CUTLER, of Cannon Works, 75 Constitution Hill, Birmingham, in
the County of Warwick, Manufacturer, do hereby declare the nature of my
said 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 my invention is to effect improvements in the manufacture of gold,
silver, and bronze paints, my improved paint not being liable to tarnish by exposure
to the atmosphere or gases.
In carrying out my invention. I dissolve pyroxylin in spirits, ethers, essences or
acids, whereby I obtain a suitable form of celluloid in a liquid state. Preferably
I take redistilled acetate of amyl, and dissolve therein pyroxylin, or gun cotton, so
as to render it of the consistence of cream.
I then mix with the liquid celluloid, enough gold, silver, or bronze powder, to
bring it to the consistence of ordinary paint. The paint may then be applied with
a soft brush in the usual manner.
The powder being of greater specific gravity than the celluloid, sinks at once,
and leaves a transparent coating of celluloid, which is water and air proof, and
which therefore acts as a protection against atmospheric, gaseous, climatic, and
other influences; and the brilliance of the paint is preserved.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, declare that what I
claim is :-
The improved manufacture of paint, consisting of the mixture of liquid celluloid,

page_text: with gold, silver, or bronze powder; such celluloid being obtained by dissolving
pyroxylin in spirits, ethers, essences, or acids, or by dissolving pyroxylin in
redistilled acetate of amyl, substantially as described.
