IMPROVEMENTS IN THE ORNAMENTATION OF GLASS AND THE LIKE
The present invention relates to a method for producing paintings upon glass,
ceramic wares and other objects and has for its object in the first place the
production of an imitation of glass paintings which posesses entirely the character
of genunine ones. It may however be likewise used to ornament and decorate in
a cheap and rapid manner ornamental glass ware ceramic products plaster casts
and similar articles.
For producing the effect of colouring of a painting I use in all cases artificially
coloured liquid gelatinous materials, for instance collodium or gelatine, whether of
vegetable or animal origin which floated or poured upon the articles to be decorated,
form transparent or translucent layers of colour. The outline may be formed for
instance upon plates of glass, either by metal foil, (by helio plastic processes and the
like) or by the layer of colour previously applied the excess being in the latter case
eliminated by cutting out and removal
When glass or glazed surfaces are to be ornamented they are first cleaned and
prepared in the manner well known in photo-lithography so that the layers then
poured or floated on may adhere well. The drawing and with it the out-lines of
the coloured design are laid on or applied to the surface to be ornamented in black
or in an other dark colour, either by hand or mechanically, before the coloured
films are poured on; for glass plates they will be advantageously applied to the
back of the plate. In any case the drawing shows through the coloured layers so
that the whole assumes the appearance of genunine glass painting
To more clearly present the nature of this invention I shall herein after describe
as an example the production of a piece of painted glass according to this process.

page_text: On the parts at the back of the plate which mark the outline the drawing
produced in an ordinary colour say black, is indicated, and there strips are placed
in the front of the plate which divide the seperate parts or spaces where colouring
is produced by floating or pouring. The strips may be produced as stated in
various ways for instance by covering the whole plate treated as before mentioned,
with colourless gelatine, removing when the layer as become hard those parts (by
cutting them out) which are subsequently to be filled with coloured gelatine.
When spaces have thus be produced for the various parts of the picture the spaces
are poured full with the appropriate coloured material and are allowed to become
rigid or hard. If in one space several colours are to be placed in immediate
proximity such space is first entirely filled with one colour and from the hardened
layer those parts are cut out which are to be differently coloured and the spaces
thus produced are then filled with the proper colour. Smaller parts may be put in
by brush and several layers may be placed one above the other
To attain further effects both sides of the transparent object to be ornamented 1
may be covered with coloured films in the described manner.
When the painting is finished the picture thus produced may be protected by a
covering of say varnish or by a glass plate

IMPROVEMENTS IN THE ORNAMENTATION OF GLASS AND THE LIKE "
The present invention relates to a method for producing pictures upon glass,
ceramic wares and other objects, and has for its object in the first place the
production of an imitation of glass-paintings which possesses entirely the character
of genuine ones. It may however be likewise used to ornament and decorato in a
cheap and rapid manner ornamental glass-ware, ceramic products, plaster-casts and
similar articles.
For producing the effect of colouring of a painting, I use in all cases artificially
coloured liquid gelatinous materials, for instance collodium, gelatine whether of
vegetable or animal origin, which, floated or poured upon the articles to be
decorated, form transparent or translucent layers of colour. The outline may be
formed for instance upon plates of glass, either by metal-foil, by helioplastic
processes and the like or by the layer of colour previously applied, the excess being
in the latter case eliminated by cutting out and removal.
When glass or glazed surfaces are to be ornamented, they are first cleaned and
prepared in the manner well known in photo-lithography so that the layers then
poured or floated on may adhere well. The drawing and with it the outlines of
the coloured design are laid on or applied to the surface to be ornamented in black
or in another dark colour, either by hand or mechanically, before the coloured films
are poured on; for glass plates they will be advantageously applied to the back of
the plate. In any case the drawing shows through the coloured layers, so that the
whole assumes the appearance of genuine glass painting.
To more clearly present the nature of this invention I shall hereinafter describe
as an example the production of a piece of painted glass according to this process
referring myself to the annexed drawing.
The drawing represents a part of the glass plate in section on a considerably
exaggerated scale. On the parts at the back of the plate a which are marked i the
drawing produced in an ordinary colour, say black, indicates where strips o are to
be placed on the front of the plate which divide the separate parts or spaces
where colouring is to be produced by floating or pouring. These strips o may be
produced as stated in various ways, for instance by covering the whole plate treated
as before mentioned with colourless gelatine and removing when the layer has
become hard those parts (by cutting them out) which are subsequently to be filled
with coloured gelatine. When spaces have thus been produced for the various
parts of the picture, these spaces are poured full with the appropriately coloured
material and are allowed to become rigid or hard. If in one space one or more
colours are to be placed in immediate proximity, such space is first entirely filled
with one colour and from the hardened layer those parts are cut out which are to
be differently coloured and the spaces thus produced are then filled with the proper
colour. Smaller parts may be put in by the brush and several layers may be
placed one above the other.
To attain further effects both sides of a transparent object to be ornamented may
be covered with coloured films in the described manner.
When the painting is finished, the picture thus produced may be protected by a

page_text: Having now described the nature of said invention and the manner of performing
the same, I wish it to be understood that what I claim and desire to protect under
the hereinbefore in part recited Letters Patent is :
The process of ornamenting glass, ceramic articles and other objects by pouring
or floating upon the articles upon which a design has been produced, a
gelatinous material such as collodion or gelatine, which on hardening forms a
firm transparent or translucent coating, the drawing or design together with
the coating producing the characteristic ornamental effects substantially as set
forth.
In witness whereof I the said Victor Blüthgen have hereunto set my hand and
seal this sixth day of March in Year of Our Lord one thousand eight hundred
and eighty-four.
