  Verfahren zur Durchfärbung von Marmor und anderen natürlichen Gesteinen mit Metallsalzniederschlägen. 



   Um natürlichen, kristallinischen Gesteinen, im besonderen Marmor, eine dauerhafte,   unveränderliche Färbung zu   erteilen, ist es erforderlich, dass an der Bildung des Farbstoffes die   Substauz des (testeins wenn Marmor vorliegt, der kohlensaure Ka ! k   selbst teilnimmt, also in die Reaktionen eintritt, welche sich zwischen den in die Gesteinsmassc eingeführten Lösungen abspielen. Im Sinne dieser Erfindung weden Metaloleate oder sonstige Metallseifen, in ätherischen Ölen gelöst, zugleich mit starken organischen Sauren in   den Stein eingeführt. Erst   beim Erwärmen der Steine kommt die organische Säure zur Wirksamkeit, treibt einerseits   Kohlens@ure   aus dem Marmor aus und setzt 
 EMI1.1 
 ist   die durch sie erzielte F@rbung eine durchaus unveränderliche.   



     Die praktische Ausführung des Vofahrens   ist eine recht einfache : Der Marmor wird   ill   inelll gut getrockneten heissen Luftstrome erhitzt, um ihm jede Spur von Feuchtigkeit

 unzersetzt, ebenso wie wenn sie keine freie Säure enthielte, in den Marmor ein, der nach   obigen Stunden   aus dem Bade herausgenommen und zum Trocknen in einen Ofen gebracht wird. Die Dauer des Belassens im Bade hängt von der Dichte des Marmors ab. Im Ofen verflüchtigt sich das atherische Öl sehr leicht, dann ist die Essigsäure von der Schutz-   nüssigkeit   frei   und     kann auf   den Marmor einwirken, der nun auf das Metallsalz reagiert

  Process for the coloration of marble and other natural rocks with metal salt deposits.



   In order to give natural, crystalline rocks, in particular marble, a permanent, unchangeable color, it is necessary that the substance of the (test stone, if marble is present, the carbonic acid itself) participates in the formation of the dye, i.e. it takes part in the reactions which take place between the solutions introduced into the rock mass. For the purposes of this invention, metal oleates or other metal soaps, dissolved in essential oils, are introduced into the stone at the same time as strong organic acids. Only when the stones are heated does the organic acid become effective and drive one hand, carbon dioxide from the marble and sets
 EMI1.1
 the coloring achieved by it is entirely unchangeable.



     The practical implementation of the procedure is quite simple: the marble is heated in a stream of well-dried hot air to remove any trace of moisture
 EMI1.2
 undecomposed, just as if it contained no free acid, into the marble, which after the above hours is taken out of the bath and placed in an oven to dry. The length of time it is left in the bath depends on the density of the marble. The essential oil evaporates very easily in the oven, then the acetic acid is free of the protective nut and can act on the marble, which then reacts to the metal salt

PATENT-ANSPRUCH : Verfahren zur Durchfärbung von Marmor und anderen natürlichen Gesteinen mit Metallsalzniederschlägen, dadurch gekennzeichnet, dass man Metallseifen, gelöst in ätherischen Ölen, zugleich mit starken organischen Säuren in den Stein einführt, welche, indem sie im Innern der Masse reagieren, die Bildung von beständigen bzw. unveränderlichen färbenden Produkten veranlassen. PATENT CLAIM: Process for the coloration of marble and other natural rocks with metal salt deposits, characterized in that metal soaps, dissolved in essential oils, are introduced into the stone at the same time as strong organic acids, which, by reacting inside the mass, lead to the formation of permanent resp. Induce steady coloring products.
