PROVISIONAL SPECIFICATION.
Improvements in and relating to Paints and Lacquers.
We, ALEXANDER OGSTON GILL, and WILLIAM SMITH GILL, both of the firm
of Farquhar and Gill, Paint Manufacturers, North of Scotland Color Works, in
the City and County of Aberdeen, do hereby declare the nature of our invention
to be as follows:-
[
This invention has reference to and comprises the manufacture and use of a new
or improved paint, particularly suitable as a gold, silver, or bronze paint and also
the production of a lacquer or varnish for use in combination therewith.
The improvements consist in the use of collodion, that is pyroxylin or gun-
cotton dissolved in ether or ether and alcohol or other solvents as the new and
essential element or ingredient of the paint. This is combined with bronze or other
metallic or alloyed substances in a powdered or granulated state, and of any desired
color or quantity.
In manufacturing a gold or bronze paint, these substances are taken preferably
in the proportions of about 75 to 80 per centum of collodion at a strength of say
having 3 per centum pyroxylin, (C,H,O, (NO2),), and about 20 to 25 per centum
of bronze powder, and the bronze powder may be added to the solution of collodion
or vice versa, and both agitated or mixed together in a suitable vessel.
Collodion would or may be used also as a lacquer for application to the surfaces
of articles or objects painted or coated with our gold or equivalent paints, for the
purpose of protecting the paint from atmospheric influences. And our new paint
and collodion would or may also be used as a lacquer for gilding purposes.
