A Novel Vitreo-metallic Material Suitable for Glazing and for
other Purposes in Place of Glass.
I LOUIS CHARLES ALBERT MARGUERIE of 1 Boulevard St. Denis, Paris, France,
Merchant, do hereby declare the nature of this invention to be as follows:-
My invention consists in the manufacture of a novel vitreo-metallic material suitable
for use in lieu of glass for window panes and other like purposes. The said material
is non-inflammable, unbreakable and transparent.
It is made by immersing wire gauze or metallic cloth, that formed of galvanized
iron wire being preferred-in a heated state in a thin paste or liquor formed of
soluble glass and gelatine or isinglass in proportions which will vary according to the
use to which the sheets or panes of the material are to be applied, say, for example,
two thirds of gelatine and one third of soluble glass. The sheets or pieces of wire
gauze are afterwards hung in a drying room, and before they are quite dry they are
dipped in a concentrated solution of Roman alum after which they are again dried
when they will be ready for use.
Coloring matters in any suitable proportions may be incorporated with the gelatine
so as to produce sheets or panes of any desired color or shade; or by applying
colored pastes or liquids with a brush transparent mosaics can be produced.
Among other uses to which my vitreo-metallic sheets or panes may be applied with
great advantage I may mention ornamental lamps.
Dated this 5th day of May 1887.

A Novel Vitreo-metallic Material Suitable for Glazing and for
other Purposes in Place of Glass.
I, LOUIS CHARLES ALBERT MARGUERIE of 1 Boulevard St. Denis Paris, France,
Merchant, 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 :-
My invention consists in the manufacture of a novel vitreo-metallic material suitable
for use in lieu of glass for window panes and other like purposes. The said material
is unbreakable and transparent.
It is made by immersing wire gauze or metallic cloth-that formed of galvanized
iron wire being preferred-in a heated state in a thin paste or liquor formed of soluble
glass, gelatine or isinglass and glycerine or glucose in proportions which will vary
according to the use to which the sheets or panes of the material are to be applied,-
say for example, 10 to 15 per cent. of glycerine or glucose and the remaining 90 to
85 per cent. being two thirds gelatine and one third soluble glass. The sheets or
pieces of wire gauze are afterwards hung in a drying room, and before they are quite
dry they are dipped in a concentrated solution of chrome-alum or bichromate of potass
after which they are again dried when they will be ready for use.
Coloring matters in any suitable proportions may be incorporated with the gelatine
so as to produce sheets or panes of any desired color or shade; or by applying colored
pastes or liquids with a brush transparent mosaics can be produced.
The vitreo-metallic sheets or panes can be coated with a protective varnish of any
suitable kind, such for example, as a copal varnish.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to he performed, I declare that what I
claim is :-
The novel vitreo-metallic material manufactured substantially as hereinbefore
described and suitable for glazing or other purposes.
