PROVISIONAL SPECIFICATION.
A New or Improved Manufacture of Artificial Stone or Composition
and Building Blocks, and other Articles thereof.
We, FRANZ JURSCHINA, of 1 Hartmanngasse 1, Vienna, Austria, Chemist and
RUDOLF RITTER VON GUNESCH of HI Obere Weissgarberstrasse 5, Vienna
aforesaid, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to the manufacture of an artificial stone or com-
position suitable for building and other purposes that is characterized by hardness
and by the sharpness of its grain. It is composed of a mixture of more or less
finely ground quartz sand or flint gravel, Tripoli, and of Portland cement, which
mixture is made with a solution of soda water glass into a paste or plastic mass that
can be pressed or cast in moulds. Suitable proportions are 100 parts of the ground
quartz sand or flint gravel from 1 to 4 parts of Tripoli, and from 1 to 6 parts of
Portland cement, the solution of soda water glass used being of from 25°
to 38° B.
The degree of fineness to which the above mentioned materials must be ground
will depend upon the intended use of the product or in other words of the articles
to be produced from the mass, which is very suitable for the manufacture of building
blocks paving blocks or slabs ornaments facings for facades, grindstones, and for
the manufacture of fire-proof and acid proof vessels and linings.
If the materials are ground to a sufficient degree of fineness, the composition can
he employed for making moulds or matrices of the finest character for the casting
of ceramic products, ornaments plastic articles of all kinds, and even of type,
locks and stereotypes for printing purposes, inasmuch as the composition when
ressed or cast in moulds, fills up the smallest spaces and gives very sharp and
exact impressions or castings. In cases where hardness is required rather than
harpness of the articles made of this composition in moulds such articles after being
aken out of the moulds, are dried under cover then burned in ordinary or suitable
ilns or burning ovens at a glowing heat and afterwards allowed to cool slowly.
Articles of finer kind are produced by pressing or casting the composition in
oulds of metal, wood, plaster of Paris, sulphur, glue, gelatine or caoutchouc, then
fter setting hard the articles so produced are taken out of the moulds and com-
letely dried with a moderate heat.

and by the following statement :-

ground quartz sand or flint gravel, Tripoli, and of Portland cement, which mixture
is made with a solution of soda water glass into a paste or plastic mass that can be
pressed or cast in moulds.
Suitable proportions are 100 parts by weight of the ground quartz sand or flint
gravel, from 1 to 4 parts by weight of Tripoli, and from 1 to 6 parts by weight of
Portland cement, the solution of soda water glass used being of from 25°
to 38° B.
The degree of fineness to which the above mentioned materials must be ground
will depend upon the intended use of the product or in other words of the articles
to be produced from the mass, which is very suitable for the manufacture of building
blocks paving blocks or slabs, ornaments, facings for facades, grindstones, and for
the manufacture of fire-proof and acid-proof vessels and linings.
If the materials are ground to a sufficient degree of fineness, the composition can
be employed for making moulds or matrices of the finest character for the casting
of ceramic products, ornaments, plastic articles of all kinds, and even of type, blocks
and stereotypes for printing purposes, inasmuch as the composition when pressed
or cast in moulds, fills up the smallest spaces, and gives very sharp and exact
impressions or castings.
In cases where hardness is required rather than sharpness of the articles made
of this composition in moulds such articles after being taken out of the moulds, are
dried under cover, then burned in ordinary or suitable kilns or burning ovens at a
glowing heat and afterwards allowed to cool slowly.
Articles of finer kind are produced by pressing or casting the composition in
moulds of metal, wood, plaster of Paris, sulphur, glue, gelatine or caoutchouc; then
after setting hard the articles so produced are taken out of the moulds and com-
pletely dried with a moderate heat.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. Artificial stone or composition for building or other purposes consisting of an
intimate mixture substantially in the proportions hereinabove stated of more or less
finely ground quartz sand or Hint gravel, Tripoli, and Portland cement, such mixture
being rendered plastic or pasty with a solution of soda water glass of from 25°
to 38° Beaumé.
2. The manufacture as described of building blocks paving blocks or slabs, orna-
ments, grindstones, vessels linings, moulds and like or analogous articles by
pressing or casting in suitable moulds as set forth plastic composition such as referred
to in the preceding claim.
3. Building blocks, paving blocks or slabs, ornaments, grindstones, vessels,
linings, moulds and like or analogous articles manufactured or produced as described
of artificial stone or composition such as referred to in claim 1.
