COMPLETE SPECIFICATION.
An Artificial Stone Composition.
We, JOSEPH EVERHARD KESELING and CHARLES FUCHS Jr., both of
No. 5 Bowling Green, New York City, State of New York, United States of
America, Chemists, do hereby declare the nature of our invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
Our invention relates to a composition of matter for the manufacture of artificial
stone and consists of a basic cement of oxide of magnesium and chloride of
magnesium to which is added asphaltum and a suitable filling material such as
sand, and diluting liquids.
We
have found by experiments and tests, that for some articles and purposes, we
can use a solution of caseine with the albumen solution. The caseine is cheaper
than albumen and by using it in a certain proportion with the albumen—a diluting
liquid is obtained which gives good results. In articles of low elasticity and heat
conducting such as coating material, we can profitably use the caseine solution in
connection with the albumen. It is understood that a certain elasticity and
tenacity is given to the material by the asphaltum. By the addition of the
albumen and caseine solution, we can make the composition sufficiently fluid to flow
freely from a brush; or if a less amount of the solution be used, it will be rendered
more paste like, and suitable as mortar.
The use of the cheaper and weaker solution of caseine with the albumen does
not prevent our using suitable pigments to obtain a desired color in the composition.
We have found that if the caseine was used alone as a dilutant, or if in excess of
the albumen, the material became brittle, but when used in about the proportions
below stated the material gave good results and at less cost than if albumen
alone was used.
For general purposes we use the ingredients herein mentioned in about the
following proportions:
Sand, seventy (70) pounds.
Oxide of magnesium, thirty pounds (30 lbs.).
Chloride of magnesium solution, twenty pounds (20 lbs.).
Asphaltum solution, two pounds (2 lbs.).
Albumen solution, five pounds (5 lbs.) (in the proportions of 3 to
Caseine solution, 4 lbs. albumen to 2 to 1 lbs. caseine solutions).
The strength of the magnesium chloride solution is from 32° to 34° Beaume.
The asphaltum solution consists of lb. asphaltum dissolved in 1 gallon of
turpentine. The albumen solution is made by dissolving oz. yellow egg albumen
in 24 lbs. pure water at a temperature of 145° F. The caseine solution is obtained
by dissolving oz. caseine and oz. caustic soda in 24 lbs. pure water at a
temperature of 145° F.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The herein described composition of matter for the manufacture of artificial
stone, which consists of a basic cement of chloride and oxide of magnesium, sand
