PROVISIONAL SPECIFICATION.
Improvements in or relating to Bronze or other Metallic Paints.
We, EDITH COURTNEY WILLIAMS, and MINNIE ELIZABETH WILLIAMS, both.
of Rushmoore, Liscard, in the County of Chester, and CHARLES MAY, of 56, Lord
Street, Liverpool, in the County of Lancaster, Goldsmith, do hereby declare the
nature of this. invention to be as follows:-
This invention has for its object an improved paint or enamel having a body of
bronze powder or other powdered metal.
The great difficulty in the past has been to find a suitable menstruum, which will
paint well and yet not separate quickly from the powder, but will hold the latter
well in suspension. Several attempts that have been made turned out failures,
either owing to the fact that the menstruum was such that it would not keep an
intimate admixture of bronze powder, or that the paint would not dry quickly, or
that the ingredients used were liable to oxidise the metallic powder.
Our invention is designed to fulfil the requisite conditions.
The following is the receipt, namely:-
Acetate of amyl (with a little amyl alcohol) about 95 parts;
Gun cotton about 4 parts.
To make this mixture, it is only necessary to put the required weight of collodion
gun cotton in a vessel and add the acetate of amyl, shaking occasionally until the
gun cotton is dissolved. A suitable quantity of bronze or other metallic powder is
then added. The acetate of amyl employed may be the commercial article which
always contains amyl alcohol.
It must be distinctly understood that we do not limit ourselves to the exact
proportions described, or even to the precise compounds above set forth, as other
ingredients of analogous composition may be used.
Dated this 1st day of March 1892.

Improvements in or relating to Bronze or other Metallic Paints.
We, EDITH COURTNEY WILLIAMS and MINNIE ELIZABETH WILLIAMS,
both of Rushmoore, Liscard, in the County of Chester, and CHARLES MAY of
56, Lord Street, Liverpool, in the County of Lancaster Goldsmith, 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:-
This invention has for its object an improved paint or enamel having a body of
bronze powder or other powdered metal.
The great difficulty in the past has been to find a suitable menstruum, which will
paint well and yet not separate quickly from the powder, but will hold the latter
well in suspension. Several attempts that have been made turned out failures,
either owing to the fact that the menstruum was such that it would not keep an
intimate admixture of bronze powder, or that the paint would not dry quickly, or
that the ingredients used were liable to oxidise the metallic powder.
Our invention is designed to fulfil the requisite conditions.

page_text: The following is the receipt, namely :-
Acetate of amyl (with a little amyl alcohol) about 97½ parts)} by weight
Gun cotton about 2 parts
Bronze or other metallic powder about 2 pounds to the gallon of this mixture.
To make this mixture, it is only necessary to put the required weight of collodion
gun cotton in a vessel and add the acetate of amyl, shaking occasionally until the
gun cotton is dissolved. The bronze or other metallic powder is then added and
dissolved. The acetate of amyl employed may be the commercial article which
always contains amyl alcohol. A little colouring natter may be added, if desired.
It must be distinctly understood that we do not limit ourselves to the exact
proportions described, or even to the precise ingredients above set forth, as, instead
of acetate of amyl, any known solvent may be used.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. The manufacture of bronze or powdered metal paint substantially as
described.
2. A metallic paint formed of bronze or other powdered metal, acetate of amyl
or other solvent and collodion gun cotton, with or without colouring matter, sub-
stantially as described.
