PROVISIONAL SPECIFICATION.
Improved Means and Process for Treating Iron and other Metals and
the Production of a Fireproof Coating thereon Preparatory to
Ornamenting with Fusible Colours.
I, JOHANN MEESE, of Leer, Prussia, Manufacturer, do hereby declare the nature of
this invention to be as follows
--
This invention relates to a novel method or process of treating iron and other metals
preparatory to coating them with a vitrifiable or other body, plain or coloured, for
ornamenting and general embellishment.
After repeated experiments I have been led to manufacture a durable and fireproof
material for coating iron and other metals, my process having, as compared with those
hitherto known, the advantage of great simplicity combined with cheapness. The
colour of the coating has a light shade and a dull appearance, these properties
being of the greatest value for the further treatment of the metais by means of
fusible colours, as it is only upon a light ground that the fusible colours fully
exhibit upon iron their original beauty or brilliancy. A light coloured and dull
ground has only been hitherto obtained by means of aluminium and this product
has still such a high value in commerce at the present time that it can scarcely
be employed on a large scale in practice.
My process consists in first preparing oxide of nickel and in adding to the
finely triturated powder of this oxide a small percentage of powdered chromate of
iron. With this powder I further mix a lead glass flux, such as can be purchased
in the market and I triturate the whole mass with a mixture of stearic oil and oil
of turpentine in a shell, cup or mortar. I subsequently smear this mixture thinly
upon the object requiring to be ornamented or decorated and calcine it in a muffle or
in a furnace.
Upon the objects thus treated, fusible colours or metals in the form of powder can
be applied and burnt in. I may also give the described mixture or otherwise ground
shade another character as I can add directly thereto fusible colours or metals in the
form of a powder.
The chief features of novelty are :-
1. The use of a mixture of nickel oxides and chromate of iron in the form of a
powder with oil of stearine and oil of turpentine with the addition of a lead glass
Hux. such as can be procured in commerce for the preparation of a durable fireproof
coating material for iron and other metals which is fired thereon by fusion.
2. The use of the mixture as above in combination with fusible colours and
metals in a powdered form for the purpose mentioned.

COMPLETE SPECIFICATION.
Improved Means and Process for Treating Iron and other Metals and
the Production of a Fireproof Coating thereon Preparatory to
Ornamenting with Fusible Colours.
I, JOHANN MEESE, of Leer, Prussia, Manufacturer, do hereby declare the nature of
this invention and in what manuer the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to a novel method, or process of treating iron and other
metals preparatory to coating them with a vitrifiable, or other body, plain or coloured,
for ornamenting and general embellishment.

page_text: After repeated experiments, I have been led to manufacture a durable and fire-
proof material for coating iron and other metals, my process having as compared with
those hitherto known, the advantage of great simplicity combined with cheapness.
The colour of the coating has a light shade and a dull appearance, these properties
being of the greatest value for the further treatment of the metals by means of fusible
colours, as it is only upon a light ground that the fusible colours fully exhibit upon
iron their original beauty or brilliancy.
A light coloured and dull ground has only been hitherto obtained by means of
aluminium and this product has still such a high value in commerce at the present
time that it can scarcely be employed on a large scale in practice.
My process consists in first preparing say 200 parts of oxide of nickel and in adding
to the finely triturated powder of this oxide 25 parts of powdered chromate of iron.
With this powder, I further mix 300 parts of lead glass flux, such as can be purchased
in the market and I triturate the whole mass with a mixture of 1 part stearic oil and 5
to 7 parts oil of turpentine in a shell, cup, or mortar. I subsequently smear this
mixture thinly upon the object requiring to be ornamented, or decorated and calcine
it in a muffle, or in a furnace. The oxide of nickel, chromate of iron, and lead glass
flux or paste may be mixed in other proportions according to the shade required.
Upon the objects thus treated fusible colours, or metals in the form of powder can
be applied and burnt in. I may also give the described mixture, or otherwise ground
share another character, as I can add directly thereto fusible colours, or metals in the
form of a powder.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The employment of a mixture of nickel oxides and chromate of iron in the form
of a powder with oil of stearine and oil of turpentine with the addition of a lead glass
flux, such as can be procured in commerce, for the preparation of a durable fire proof
coating material for iron and other metals, which is fixed thereon by fusion.
2. The use of the mixture claimed above in combination with fusible colours and
metals in a powdered form for the purpose mentioned in claim 1.
