I CARL STRAUB, of 28 Wayne Street, Syracuse; in the County of Onondaga, and
State of New York, United States of America, Sculptor, do hereby declare the
nature of this invention to be as follows:
My invention consists in the composition forming a new building material for
various purposes as will be hereinafter fully described.
In compounding the composition referred to, I mix glue and water together
under a moderate heat so as to produce a thick fluid; after which I add a quantity
of boiled linseed-oil, the proportions being seven parts of the fluid to one of
the oil.
· After the oil has been thoroughly intermixed with the gluey fluid, I add either
muriatic or sulphuric acid, adding about as much muriatic acid as I did oil; but if
I use sulphuric acid, using only one third as much:
This mixture is thoroughly stirred for a quarter of an hour or more, having been
kept heated up to this point. The mixture is then removed from the heat and
stirred till cool. After cooling, the mixture is allowed to stand about three days,
but during this time must be stirred three times a day for five or ten minutes at a
time. At the end of three days the fluid will be found to be quite thin and should
then be covered in order that it may be kept from the action of the atmosphere.
The solution above described may be kept almost any length of time desired,
and when it is desired to form any quantity of artificial marble one part of the
solution is mixed with twenty parts of water, the mixture readily dissolving in
water. Plaster of Paris is then sprinkled into the diluted solution, care being
taken to stir the solution while the plaster is being added. Enough plaster should
be added to form a dough as thick as moulding clay, which dough should be
thoroughly kneaded either by hand or by a proper kneading machine. After this
dough is formed it, may be pressed into any shape or form desired and may be
colored by any of the well known pigments.
If variegated marble is to be formed, separate batches of differently colored
doughs may be united, as will be well understood by those skilled in the art.
Artificial marble manufactured by the aid of my improved solution is particularly
well adapted for ornamental work, as it is quickly and easily manipulated and iş
capable of receiving a high polish.

page_text: It will of course, be understood that the dough could be pressed into ornamental
shapes and forms as well as into plain flat tablets, and it will also be understood
that the proportions of the ingredients may be varied, the main point being the
materials employed and the method by which they are united.
If the material is to be used for covering walls or for other like purposes, it is
desirable that it should be in a dry friable condition, and in such cases the com-
position is prepared as follows.
I mix 80 pounds of glue and 80 pounds of water under a moderate heat so as to
produce a thick fluid, after which I add a quantity of boiled linseed-oil, 16 pounds
of such oil being used. When the oil has become fully intermixed with the gluey
-fluid, I add 22 pounds of muriatic acid and 5 pounds of sulphuric acid, and after
the addition of the acids the mixture is heated to about 450 degrees and thoroughly
mixed by stirring, the mixture is then allowed to cool and to stand about three
days during which time it is stirred three or four times a day for 5 or 10 minutes
at a time. At the end of the period named 16 parts of water are added to 1 part
of the mixture, the combined mixture and water being placed in a shallow pan in
order that there may be sifted into it without stirring, as much of the following
material as is necessary to fully absorb all of the solution.
The material referred to consists of 1 part of calcined sulphate of lime to about
th part of calcined carbonate of lime. The mass formed by the addition of the
ingredients just named is allowed to stand until dry, or, if desired, the process of
drying may be accelerated by the application of heat.
If it is desired that the product shall have any particular color, the dry coloring
is added to the lime and plaster before sifting into the fluid, the color and lime and
plaster being thoroughly mixed. This insures an equal coloring throughout the
mass.
In drying, this material will be found to be friable and may be used for the
purpose of finishing walls and for such other purposes as may be desired, a
sufficient quantity of water being added prior to the application of the material to
the wall to make a thick plaster.
In certain instances it will be desirable to cheapen, harden and make other
qualities of the dry material, and in order that this may be done a mixture is
made as follows: to one part of the dry material already described add from
2 to 16 parts of sulphate of lime and from 3 to 12 parts of dry washed sand, the
proportions varying in accordance with the quality of the material which the
operator wishes to produce, and this reproduced material may be applied in the
manner heretofore described, by mixing with water to the consistency of mortar,
which can be readily applied to laths or bricks as a base for walls, the first
described material being laid on for a finish.
The material described has great adhesiveness, holding firmly to lath, wood or
iron without keying, and also adhering firmly to brick or stone and becoming in a
short time as hard as stone, although having a certain amount of elasticity.. The
material described will also resist the action of fire and water to a much greater
extent than any of the so called fire and water proof materials now in use.
In compounding the composition care should be taken that the proportions
above given be accurately followed, as otherwise the material becomes hard instead
of drying in a friable mass.
