ADOLPH ANHOLT of 6 White Lion Street Bishopsgate London E.C. in the
County of Middlesex Agent, do hereby declare the nature of this invention to be as
follows:-
:-
The object of my invention is to substitute glass for marble or other stone in
almost all cases for which the latter can be used giving to the glass by various
processes the same tints colours & general appearance as marble. For this
improvement I use pure transparent glass or, if preferred, plate glass. The glass
is heated gradually to a very high temperature great care being taken in this
process to prevent breakage. The glass is then covered with a thin coat of paint
which gives it the first resemblance to marble. Before this paint has quite dried
on the heated glass further various mixtures of paints are carefully poured on the
surface in such a manner as to give the surface the various colours & tints it may
be desired to produce to resemble the different kinds of real marble. It will be
understood that it is in the mixing & blending of the various paints & colours
& the manner in which they are poured on to the glass that the success of the
improvement lies. Thus the paints are carefully proportioned, arranged, well
ground, purified & chemically prepared & dissolved in gum arabic & water. When
all the paints have been applied & the glass has assumed the desired marble tint &
appearance it is placed in a well heated room about 23 grades Reaumur & when
perfectly dry the glass is slightly varnished with dissolved shellac & spirits so as
to fasten the colours well, this varnishing process being frequently repeated. The
glass is then repeatedly & carefully rubbed with alum & water & after a period of
three days an oil varnish applied after which the glass assumes the exact appearance
of marble, the repeated varnish being applied not only to smooth the surface but
also to prevent either damp or heat from having any influence on same.

ADOLPH ANHOLT of No. 6 White Lion Street, Bishopsgate, London E.
Agent, do hereby declare the nature of this invention a communication from
Moritz Hartmann trading as Koch Brothers of Amsterdam, Holland 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 substitute glass for marble or other stone in
almost all cases for which the latter can be used giving to the glass by various
processes the same tints colours and general appearance as marble or similar stone.
For this improvement I use pure transparent glass or if preferred, plate glass.

page_text: The glass is placed in a well heated room and heated gradually to a very high
temperature, great care being taken in this case to prevent breakage. The under
surface of the glass is then covered with a thin coat of paint which gives it the
first resemblance to marble. Before this paint has quite dried on the heated glass
further various mixtures of paints are carefully poured on the same surface in such
a manner as to give this surface the various colors & tints it may be desired to
produce, to resemble the different kinds of real marble, the paints varying in
accordance with the colors & tints the marble is to assume.
By means of the different kinds of paints & colors used, any species of marble,
granite or similar stone can be successfully imitated, inlaid marble being also well
imitated by this means. The appearance of porcelain can also be given to the
glass by means of the paints used. It will be understood that it is in the mixing
and blending of the various paints & colours & the manner in which the colours are
poured on to the glass that the success of the improvement lies. Thus the paints
are carefully proportioned & arranged, well ground, purified & chemically prepared
& dissolved in gum arabic & water. When all the paints have been applied &
the glass has assumed the desired tint & appearance required on the stone, it is
again placed in a well heated room about 23 grades Reaumur & when perfectly
dry the painted under surface of the glass is slightly varnished with dissolved
shellac & spirits so as to fasten the colours well, this process of varnishing being
frequently repeated. The glass is then carefully & repeatedly rubbed on its
painted side with alum & water, & after a period of 3 days an oil varnish is
applied to this side following which the glass assumes the exact appearance of
the stone required, the repeated varnish being applied so as to prevent either damp
or heat from having any influence on same.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is
The manipulation of glass which when prepared can be made to assume the
exact appearance of marble, granite, porcelain or similar stone.
