1, OSWALD LINDNER, of 89 Gumpendorferstrasse, Vienna VI, in the Empire of
Austria, Turner do hereby declare the nature of this invention to be as follows:-
-
This invention relates to the decoration or ornamentation of surfaces of wood, paper,
leather, metal, pottery and the like.
According to the said invention, the surface to be ornamented is painted over or
coated with a solution of glue mixed with a colouring matter, and then the thin layer
of glue is allowed to dry, whereby it shrinks and becomes cracked, the fissures and
crevices representing markings similar to those of crocodile skin.
Instead of mixing the colouring matter with the solution of glue, the same may be
used in the form of dust strewed over the glue paint, or a liquid colour may be painted
over the half-dried glue.
By treating the gluc covering with an extract of horse-chesnuts, with tannic acid,
or chromic acid or with some material suitable for rendering the glue insoluble,
durability is given to the described ornamentations.
+
When ceramic objects are to be ornamented in the described way, the usual
vitrifiable or earth colours are mixed with glue, and the painted objects are burned as
usual, whereby the glue will be wholly consumed by the fire and the painted surface
will assume the cracked appearance.

page_text: Improvements relating to the Decoration or Ornamentation of
Wood, Paper, Earthenware, and other Surfaces.
1, OSWALD LINDNER of 89, Gumpendorfer-Strasse, Vienna VI in the Empire of
Austria, Turner, 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 :-
This invention relates to the decoration or ornamentation of surfaces of wood, paper,
leather, pottery and the like.
According to the said invention, the surface to be ornamented is painted 'over or
coated with a moderately concentrated solution of glue, mixed with a colouring inatter.
This coating or layer of glue which is thin is allowed to dry, and during the drying it.
shrinks and becomes crackled, the fissures and crevices representing markings similar
to those of a crocodile skin.
It'is to be understood that, on the one hand the more rapidly the drying is per-
formed the more closely will the fissures and crevices crowd together, and that, on the
other hand the more concentrated the solution of glue the more rapidly will the
drying take place provided that all other conditions be unvariable. Owing to these
facts, it is possible to vary at pleasure the number of crevices per unit of surface, as
different degrees of concentration and different terms of drying may be combined in
numerous ways.
Instead of mixing the colouring matter with the solution of glue, it may be applied
in the form of dust scattered over the glue-coating,'or a liquid colour may the painted
over the half dried glue.
In order to give the ornamentations made in the described manner great durability
and the appearance of leather, the glue coating is treated with an extract of horse-
chestnuts, with tamic acid, or chromic acid, or with some other material suitable for
rendering the glue insoluble.
When ceramic objects are to be ornamented in the described manner, the usual
vitrifiable or earth colours are mixed with glue, and the painted china or earthenware
objects are burned as usual, whereby the glue will be wholly consumed by the fire and
the painted surface assume a crackled aspect.
Instead of using animal glutine, other sorts of glue may be used, as well as gums
and even oil-paints.
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 :-

page_text: First. The decoration or ornamentation of surfaces of any kind, by coating or
covering these surfaces with a moderately concentrated solution of glue which is
coloured, before or after its application; drying this coating in a sufficiently rapid
manner to cause it to shrink and become crackled; and finally treating the said coating
with tannic acid or other substance by which it is rendered insoluble.
Second. The decoration or ornamentation of surfaces of any kind, by coating or
covering these surfaces with a moderately concentrated solution of gum, which is
coloured before or after its application; or with an oil-paint, and drying the coating in
a sufficiently rapid manner to cause it to become crackled.
