PROVISIONAL SPECIFICATION.
Improvements in Translucent Plastic Compositions.
I, FRIEDRICH ECKSTEIN, of V Siebenbrunnen Gasse, 15, Vienna, Austria, Chemist,
do hereby declare the nature of this invention to he as follows:-
This invention has for its object a horny, translucent plastic composition of great
tensile strength and considerable elasticity, which may be used as a cheap and
inodorous substitute for celluloid, and can be worked, dyed, pressed denitrated, and
rendered incombustible or fire proof.
The novel composition which I term "hyaline" consists of a mixture of about equal
parts of gun cotton and colophony, or shellac, copal, dammar, turpentine or of any
mixture of these resins. The gun cotton is dissolved in ether, ether alcohol, methylic
ether, or acetic ether, or in a mixture of these solvents, and to the solution about an
equal quantity of any of the resins mentioned is added. Or the resin or mixture of
resins may be dissolved in any of the solvents mentioned or in any mixture of them
and in the thick lacquer thus obtained a quantity of gun cotton is dissolved sufficient
to produce a gelatinous mass. When allowed to dry in the air, this mass soon
hardens and forms a horny material, which is the "hyaline."
Dated this 16th day of September 1889.

Improvements in Translucent Plastic Compositions.
I, FRIEDRICH ECKSTEIN of V Siebenbrunnen Gasse 15, Vienna, Austria, Chemist,
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 has for its object a horny translucent plastic composition of great
tensile strength and considerable elasticity, which may be used as a cheap and
inodorous substitute for celluloid, and can be worked, dyed, pressed denitrated, and
rendered incombustible or fire proof.
The novel composition which I term " byaline" consists of a mixture of about
equal parts of gun cotton and colophony, or shellac, copal, dammar, turpentine or of
any mixture of these resins. The gun cotton is dissolved in ether, ether alcohol,
methylic ether, or acetic ether, or in a mixture of these solvents, and to the solution
about an equal quantity of any of the resins mentioned is added. Or the resin or
mixture of resins may be dissolved in any of the solvents mentioned or in any mixture
of them and in the thick lacquer thus obtained a quantity of gun cotton is dissolved
sufficient to produce a gelatinous mass. When allowed to dry in the air, this mass
soon hardens and forms a horny material, which is the "hyaline" the subject of
this Invention.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
The manufacture of a translucent plastic compound consisting of gun cotton and
resins such as are herein mentioned dissolved to gelatinous consistence, and dried to
a horny condition, substantially as described.
