Specification Accepted, 5th Jan., 1887.
A Process for the Production of Pictures by Cut and Stained Glasses,
which may be Applied to Window Panes and such like, as well
as for the Decoration of Facades, Partitions, and Ceilings.
I OTTO LESSING, of 51, Königin Augusta Strasse, Berlin, Germany, Sculptor, 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:
The object of this invention is, a novel process for the production of pictures, by cut
and stained glasses, which may be applied to window panes, and such like, as well as
for the decoration of facades, partitions, and ceilings.
Hitherto, pictures and devices upon glass have been produced either by painting
upon the surface, and burning in a coloured enamel, or by the conjunction of single
differently stained pieces or plates of glass, which are bound, and held in place in
proper relation to each other by "leads."
Now, in order to produce pictures upon glass, which have an effect as perfect as
hitherto the process however, being materially simplified and facilitated by the
discontinuance of the employment of "leads" and of the burning in of colours,
I proceed in the following manner.
I cut out coloured and uncoloured tablets or pieces of glass according to the shape,
the distribution of tints, and shadowing of the painting which is to be produced,
I arrange them in place and stick them at the proper temperature with a layer or
« strass," beside
coating of transparent cement, consisting, preferably, of water glass or
one another upon an ordinary plate of transparent and colourless glass (common
window glass, plate glass). The same can be painted, shaded or shaped as desired.
As a measure of safety against accidents I stick upon the above described compound
picture formed of little tablets of glass, another plate of transparent glass, as a protector,
so that the glass picture proper is between two plates of glass, which moreover can be
made air tight at the edges.
By these means I can easily and quickly produce pictures or ornaments in glass
without being under the necessity of making use of the usual "leads."
The coloured glasses, out of which the picture is built up, can be very small and thin
and yet the picture may be made of any strength that is desired.

page_text: The glass picture thus produced can be employed with equally good results, when
the light passes through it (as in the case of windows) as when used with a reflecting
background for the decoration of screens, facades and roofs or ceilings or for any other
forms of ornamentation.
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
The process for the production of pictures or designs in glass, suitable for decorating
windows, lantern lights, and such like, or for the ornamentation of Facades, partitions,
and roofs or ceilings, by securing coloured or painted tablets or pieces of glass in the
manner set forth.
