UNITED STATES PATENT OFFICE.
GEORGE WASHINGTON PARKER, OF SAN FRANCISCO, CALIFORNIA.
PROCESS OF TREATING GYPSUM ROCK TO lMlTATE CHALCEDONY.
SPECIFICATION forming part of Letters Patent No. 549,151, dated November 5, 1895.
Application filed December 22, 1894- Serial No. 532,652, (No specimens.)
To all whom it may concern:
Be it known that I, GEORGE WASHINGTON PARKER, a citizen of the United States, re= siding at San Francisco, in the county of San Francisco, State of California, have invented a new and useful Process of Treating Gypsum Rock to Imitate Chalcedony, of which the following is a specification.
My invention relates in part to processes for treating gypsum rock to impart to it a hardness and polish resembling marble; but my object is to produce a product not only superior to marble in hardness and fineness of surface, grain, and luster, but resembling in colors and general appearance the different varieties of chalcedony, such as onyx, agate, &c. To this end the crude gypsum rock is first shaped in any desired form and configuration by carving, sawing, planing, &c., and is then freed from the water constituting one of its constituent elements, next colored in accordance with the desired effect, and then it is treated to the action of hardening chemical solutions, all as more particularly set forth below. Beautiful onyx, agate, 850., effects can be produced, in accordance with the tastes and desires, in statuary, furniture ornamentations, and the like, and in the finishing of rooms, using the material in lieu of marble or woodwork. By my treatment the colors are made to appear as if a constituent part or element of the rock in its native con.
dition and formation, and the condition of the product, as stated, is superior in hardness and finish to either marble or chalcedony.
To carry my process into effect, the gypsum rock from the mines having been given the desired configuration, as stated, is submitted to the drying action of hot air for twelve hours (more or less) until all the moisture has been eliminated. The material is now calcium sulphate, porous from surface to center, and capable of absorbing sufficient chemical solution to produce the desired effect of the rock and colors. To the -surface of the dehydrated rock is now applied the mineral colors such as, for an illustration, solution of copper nitrate and aqua ammonium, or a solution of sulphate of iron, nitric acid, and potassium sulpho-cyanide, or other mineral colors. After coloring, the rockis immersed in asolution of aluminium sulphate (Al (SO for about fifteen hours or until the pores of the rock are completely filled. The material is then removed and exposed to the open air for a few hours at a low temperature and then polished.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
The process of treating gypsum rock to represent chalcedony, which process consists in first completely dehydrating the rock by the action of hot air, next allowing the now porous rock to absorb a solution of sulphate of iron, nitric acid and potassium sulpho cyanide, after which, immersing in a solution of aluminium sulphate (Al (SO,) for fifteen hours, next exposing to open air and then polishing, substantially as set forth.
In testimony of the foregoing I have hereunto subscribed my name in the presence of two witnesses.
GEORGE WASHINGTON PARKER.
