on substrates and treating them with a metal salt solution.

Patented in the German Empire on December 17, 1911.

The subject of the present invention is a method for the production of artificial Marble, granite, malachite, serpentine, labrador or the like. By casting suitable hydraulic or other substances. The method is characterized in that in a Form or on a base first a thin coating or a layer of a metal salt solution a metal that does not belong to the alkaline earth metals is applied. The metal salt used in this process can either be colorless, or it can also be added coloring material, which as a result of its coloring properties produces a coloring effect at a later stage of the procedure. On this A hydraulic mass or other pourable material is then applied, which on contact with the salt coating transforms the metal of the salt into an insoluble one Connection transferred. Depending on the way in which this mass with those in it When dyes are distributed, replicas of the structure of the various dyes are obtained Types of stone by reaction with the metal salt.

An embodiment of the method is described below:

Suitable metallic coloring substances, e.g. B.

Common compounds of lead, iron or manganese are made with a water solution a heavy metal salt mixed, e.g. B. with a 10% solution of Zinc sulfate. In addition, a substance

which will be described later, can be added to the metal salt solution to cause solidification to delay the surface. This substance gives the mass a thin and semi-liquid consistency. ,

The mass used for casting, which is made of marble cement, alabaster cement, gypsum, sorel cement, Portland cement ο. Like. Is then produced, and this can, if if desired, a compound which suitably affects the zinc sulfate can be added. This addition can, for. B. consist of calcium carbonate and in the form of powdered Marble can be applied. Several types of casting compounds can initially contain such compounds.

In order to prevent the mass from solidifying too quickly, it is advantageous to use it with To mix glue or the like, which contains some blood protein (blood albumin). These substances have a retarding effect on the solidification of the mass and can also affect the metal salt solution, which forms the coating, can be added.

The coating of metal salt is applied to the base immediately before the above called mass is poured. It can do this e.g. B. either with a spoon over the Pad is painted, or by squeezing a felt, creating the solution more or less regularly dripping onto the surface. Before the crowd the coating of metal salt is poured, dark mica, powdered pearl

Claims (1)

nut, pulp of celluloid, dry powdered casting paste ο. Like. On the coating from metal salt to be scattered to shimmering and precisely separated granular crystals produce characteristic of several valuable types of stone with special crystals are. The mass is made according to the nature of the pattern by dripping, splashing or sprinkling on the salt coating. ίο The mass is usually used with coloring Substances of the aforementioned types mixed, and this mixture is suitably by Sift the dry powder, which is to form the mass, together with the powdery one Dye causes. However, the mixture can also be carried out with the addition of water. As a rule, several colored or colorless materials are used for the same work, and these masses become thin or thin according to the nature of the pattern viscous, dough-like or moist state in a known manner by means of a broom, Sieve or placed by hand. A material that is not attacked by the salt is used for the base or form will, e.g. B. Glass; Forms of sheet metal, plaster of paris or glue can also be used but they must first be coated with a protective agent, e.g. B. with a Solution of wax in gasoline or the like. While the mass is being applied, the salt solution penetrates it. The fat ones Parts are not absorbed as much as the thin ones, and so it becomes a very natural one Pattern made while at the same time the basic alkalis or the alkaline earths that are added or are present in the mass from the start, act on the metal salt, so that they make this unsolvable. The surface of the manufactured objects is thereby hardened, so that their structure becomes denser, while different colors can arise at the same time. Zinc sulfate will z. B. transformed into white zinc hydrate or zinc carbonate, and iron sulfate turns yellowish Iron sesquioxide or similar colored compounds. When manufacturing very thick objects, the casting is carried out in several phases carried out, and when a first layer of the mass is applied, a new coating is applied applied by metal salt on its surface, after which new mass is laid etc. Since the layer formed by the salt coating and the casting compound, which is based on the described or similar way is brought to a slow solidification, still sufficiently flowing is, the formation of a certain pattern can be promoted by various movements of the base. The underlay can be exposed to vibrations or knocks, which makes the more compact parts in the Movement direction can be shifted slightly, or it can be brought into a suitable position be, so that the applied layer flows down according to the slope, whereby a particularly characteristic pattern with long veins is produced. The pattern can then be fixed by sprinkling dry or moist casting compound. The treatment described above gives the finished object a clear appearance Sounded when bumped and takes on a crystalline appearance, which structure occurs clearly when the surface is rubbed a little. The surface can also be used with suitable hardening agents are treated, e.g. B. with a solution of resin, carnauba wax or the like in kerosene or gasoline. In addition, the surface can be either with French Polish or completely polished like marble stucco. Before polishing or independently of this, the article can be impregnated with an alkali silicate solution be e.g. B. with soda water glass, with or without the addition of a substance that is easily removable Contains chlorides such as calcium chloride, zinc chloride, etc. The items can, especially if the casting is carried out on a flat surface, they can be used immediately.
