MATHILDE BOUCHE OI Gentilly or the depar
hereby declare the nature of this invention to be as follows:-
The object of my invention is to illuminate or give to various surfaces a pearly
brilliancy in imitation of real pearl; by which means, leather, stuffs, silk, linen,
flowers, birds, insects, animals, statuettes, furniture and other objects, are made to
imitate objects in pearl, and which said surfaces so treated by the process or com-
bination of processes hereinafter described, give off a rich and exquisite wavy light,
common to pearl surfaces.
Now my invention consists in superficially covering the exterior surfaces of various
objects for various purposes, both of an animate and inanimate nature; and in
carrying out the process or combination of processes, I proceed as follows:-
I take a composition or preparation of commercial gelatine or other like substance,
combined with brilliant fish scales, forming a compound mixture, which when in a
somewhat heated and semi-liquid state, is applied to the object to be illuminated, either
by spreading the said composition upon the surface to be coated, or by dipping the
article or articles in a bath containing the composition.
After
The surfaces to be coated, are previously cleansed and hardened, so that the pearly
composition shall thoroughly cake, and adhere to the objects coated or covered.
After coating, the objects are dried in the open air, or in a drying stove.
this has been done, the surface thus covered with a pearly composition in imitation of
real pearl, is coated or covered with a good and hard drying transparent varnish or
shellac, or it may be covered with any transparent coating or covering, in order to
protect the surface thus produced.
The said composition may if desired, be employed for printing, engraving, or
illuminating surfaces.
Although I have described that fish scales, and gelatine of commerce, form the best
composition, of which I am acquainted, yet other and analogous substances which are
equivalents of the said matters, may be used with like effect."

Improvements in the Pearling or Ornamentation of Surfaces.
I, MATHILDE BOUCHÉ of Gentilly of the department of the Seine, France 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 my invention is to decorate, or to give to various articles, a pearly
surface, in imitation of real mother of pearl; by which means, leather, stuffs, silk,
linen, flowers, birds, insects, animals, statuettes, furniture and other objects and articles,
are made to imitate objects in pearl, or surfaces inlaid or covered" with mother of
pearl.
The said surface, or surfaces so decorated, or illuminated, give off the brilliant hues,
and iridescent appearance, common to pearl of exquisite color.
Now my invention, consists in superficially covering the exterior surface or surfaces,
or parts of the exterior surface, or surfaces, of articles and objects, (including both
animate and inanimate nature) with a composition, consisting of gelatine, and brilliant
fish scales.
In carrying out my invention, I take ordinary commercial gelatine, or other like
gelatinous substance, and add thereto, or combine therewith, brilliant fish scales.
This compound mixture, is then heated, so as to form a semi-liquid paste or com-
position, and when in this state, it is applied to the exterior surface, or surfaces, of
objects to be pearled.
The pearling composition, while in a semi-liquid and warm state, is applied, either
by spreading a layer of the composition upon an article or surface, or dipping an
article in a bath containing the said pearling composition.
The surfaces prior to being coated, are prepared and cleaned, so that the pearling
composition, shall thoroughly adhere.
The said coating, after having been applied, is next dried, either in the open air, or
in a drying stove, so as to harden the composition: after this has been done, the
pearled surface, is coated or covered with a hard drying transparent varnish, shellac,
or other like transparent coating, so as to protect, the surface thereof, from
injury.
The said composition, may if desired, be employed for printing, engraving, or
illuminating surfaces.
Or the composition may be applied by a brush, as in painting.
Although I have described that fish scales, and gelatine of commerce, form the best
composition of which I am acquainted, yet other analogous substances, which are
equivalents of the said matters, may be used with like effect.

page_text: Having now particularly described, and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
Imitation pearling, or coating exterior surface, or surfaces, of articles and objects,
with a composition, made from, or consisting of, gelatine, or other gelatinous
substances, and brilliant fish scales; and which said composition, after hardening, is
protected by a transparent varnish, or other coating, substantially as herein
described and set forth.
