PROVISIONAL SPECIFICATION.
A Liquid Metallic Composition for Use as a. Writing or Printing Ink,
or as a Color for Decorating Surfaces.
I CHARLES BLANCAN of 156 Rue du Faubourg Saint Denis, Paris, France,
Manufacturer of Stationery, do hereby declare the nature of this invention to be
as follows:-
:-
My invention relates to a liquid metallic composition intended for use as an ink,
paint, coating, or the like, in all cases where it is desired to produce brilliant
metallic effects upon surfaces generally.
This composition consists essentially in the combination of aluminium powder
with a kind of protective varnish, either colored or not, such as an aqueous
concentrated solution of gumlac obtained by means of borax, an alkali or an
alkaline carbonate.
In order that the solution shall possess the desired properties it is necessary that
it should contain after filtration from 10 to 30 per cent. of gumlac. This varnish
may be colored with any kind of aniline colors soluble in water, the proportion of
coloring matter varying according to the shade desired, for example between
1 to 20 grammes per litre.
The liquid thus obtained is mixed with the aluminium powder, and the
composition is applied either with a pen when used as an ink for writing or
drawing or with a brush when used for decorative purposes.
After drying, the aluminium powder will be protected by the gumlac which
forms an insoluble varnish which is inalterable in air.
When a colored varnish is employed highly novel and peculiar decorative effects
may be obtained by the use of this composition.
It will be understood that I reserve the right of employing in place of the
gumlac, any other matters possessing like properties and capable of producing the
same results.
Among the applications of my new composition may be cited its use as an
indelible ink with a metallic lustre, or as an ink for printing or stamping, or as a
color for decorating and illuminating or for ornamenting images, fans and other
like uses.

in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-

like uses.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what -I
claim is :-
1. As a new industrial product, a fluid metallic composition formed by the
combination of aluminium powder with a protective varnish, either uncolored or
colored, as specified.
2. The application and employment of this novel composition particularly for
writing, drawing, printing, and decorating purposes generally.
