Aluminium or Aluminium Bronze.
I, CHARLES DENTON ABEL of No 28 Southampton Buildings, Chancery Lane in
the county
of Middlesex, Consulting Engineer and Patent Agent, do hereby declare
the nature of my invention for "THE PRODUCTION OF ARTICLES OF METAL,
(PLAIN OR ENAMELLED), GLASS, PORCELAIN KERAMIC WARE, POTTERY, FAYENCE
AND NATURAL AND ARTIFICIAL STONES WITH A COATING OR ORNAMENTATION OF
ALUMINIUM OR ALUMINIUM BRONZE " and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
Acording to this invention, aluminium or aluminium bronzo, either in the shape
of foil or as powder, is applied to the surfaces of metal (whether plain or enamelled)
glass of all kinds, porcelain keramic ware, pottery, fayence, and natural or artificial
stones for the purposes of protection or ornamentation either by the cold way or by
burning or baking, such application being effected by the aid of certain substances
BB I will now describe.
Sebacitate of alumina or resinate of alumina, that is to say alumina soap, either
neutral or basic is mixed with oil of lavender or other volatile oil, and the
aluminium or aluminium bronze, the order in which the mixture is effected being
optional. The alumina soap is prepared by forming a solution of either common
soap or resin soap and precipitating by means of alum. Or basic Aluminium
Palmitate, such as is used in soap manufacture may be used, mixed with a suitable
resin, such as copaiva resiu.
These alumina soaps are dissolved in volatile oils to form a thin lac, which is then
incorporated with the aluminium or aluminium bronze by rubbing upon glass,
porcelain or marble, to the consistency of a thin syrup.
This mixture is then applied to the metallic or other above mentioned surfaces
by means of a brush or feather, either so as to cover the whole surface or to

page_text: produce any required designs thereon, for which purpose, templates may be used,
or the mixture may be applied to the surfaces by printing.
The surfaces so treated are then exposed either to the open air or to heat which
may under circumstances be a red heat. For burning in the coating, either a
Bunsen burner a coal fire, or hot blast may be employed, or the treatment may be
effected in muffles, annealing furnaces, enamelling furnaces and the like.
The above described method is particularly applicable for providing steel and
iron with a coating of aluminium, in order to protect it from rust; this operation
may be rendered more perfect by melting the above described alumina soap
compound upon the iron or steel before the application of the aluminium coating.
This coating can be polished in any known manner. Instead of the above described
compound may be employed, in certain cases, a compound differing only therefrom
in the admixture of a flux, the nature of which may be varied according to the
nature of the article to be decorated. As the most suitable flux for most articles,
may be employed oxides of Bismuth (nitrate or basic nitrate of Bismuth oxide)
either alone or in combination with borax; also the known fluxes for burning in
metallic oxide colours, such as borax, lead quartz and fluorspar.
For articles that are already decorated with colors, the flux used for the said
colors is employed, or if a high degree of heat bo employed, the flux may be omitted,
as, by such heating, the flux of the said color is softened to such a degree that the
aluminium adheres thereto. The further treatment of the articles so coated with
aluminium is the same as described with reference to the first compound. In either
case both the aluminium coating as also the parts of the surfaces adjoining the
same may be further decorated with precious metals and metallic oxide colors.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1, The here indescribed method of coating with aluminium or aluminium bronze
powder, surfaces of metal, (either plain or enamelled), glass of all kinds, porcelain,
keramic ware, pottery, fayence and natural and artificial stones, by applying to
such surfaces a mixture of alumina soap with volatile oils and aluminium or
aluminium bronze powder, either with or without the addition of a flux.
2, The production of articles of metal, glass, porcelain, keramic ware, pottery,
fayence and natural and artificial stones with a coating of aluminium or aluminium
bronze applied thereto, substantially as herein described, either with or without the
additional ornamentation with other metals or colors.
