An Elastic Composition for Moulds.
I, EMILE HÉRISSE, of 193 Wandsworth Road, London, Engineer, do hereby
declare the nature of this invention to be as follows:-
A composition according to this invention is primarily intended as a substitute
for india rubber for flexible moulds for casting articles of confectionery.
The composition is made as follows:-Gelatine is first soaked in cold water, and
removed and melted by heat. Glucose is boiled until it becomes of the consistency
of boiled sugar, when the melted gelatine is stirred into it; then the mass is allowed
to cool to set, afterwards it is again remelted to enable the air stirred in at the
beginning to pass off. The melted mass is then poured in a mould to, cast the form
of moulds required. When cold the composition mould is removed and immersed
in a solution of permanganate of potash until the solution turns orange colour: the
mould is then removed and exposed to the air, when it becomes fit for use, for
some purposes the immersion in permanganate of potash solution is dispensed with.
Dated this 15th day of March 1894.

An Elastic Composition for Moulds.
I, EMILE HÉRISSE, of 193 Wandsworth Road, London, Engineer, 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:
A composition according to this invention is intended as a substitute for india-
rubber for flexible moulds for casting articles of confectionery, and is prepared and
made into moulds as follows:-
Gelatine is first soaked in cold water in the usual way until it becomes soft, and
is then removed from the water and melted by heat. Glucose is boiled until it
becomes of the consistency of boiled sugar when the melted gelatine is stirred into
it and the mass allowed to cool and sét, afterwards it is again melted to enable the
air stirred in at the beginning to pass off; the melted mass is then poured into a
starch plaster, metal or other suitable mould of the usual kind to form the flexible
mould required. When cold the composition mould is removed from the mould in
which it has been cast, and is immersed in a solution of permanganate of potash
until the solution turns orange colour; the mould is then taken out of the solution
and exposed to the air, when after drying it becomes fit for use.
The proportions of the ingredients for the composition employed may be varied,
but I have found the following give good results, namely. To every pound of dry
gelatine and a quarter of a pound of glucose: and for the permanganate of potash
solution :-To every ounce of permanganate of potash add one pint of water.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
A composition suitable for the production of flexible moulds for casting articles
of confectionery, consisting of an admixture of gelatine and glucose, which after
being made into a mould is dipped in a solution of permanganate of potash as
hereinbefore described.
