  Verfahren zur Herstellung von gebranntem Gips. 



     Natürlicher     Gipsstein enthält   fast stets   Fremdkorperpartikelchen, deren Anwesenheit   den Gips mehr oder weniger verschlechtert, je nachdem sie sich in grösserer oder kleinerer Menge darin vorfinden. Zweck der vorliegenden Erfindung ist es, diese   Fremdkörper vom   
 EMI1.1 
 vollkommener Bildsamkeit zu erhalten. 



   Das Verfahren wird in folgender Weise durchgeführt :
Das mittelst des aus den   Gipssteinbrüchen   gewonnenen Gipssteines in bekannter 
 EMI1.2 
 wird in Bassins einlaufen gelassen, wo sich in geeigneten Formen die in   Suspension ge-   haltenen Gipsteilchen absetzen. Nach vollständiger Abscheidung des Gipses wird das   me. hr   oder weniger geklärte Wasser aus den Bassins abgeleitet und eine neue Menge (lipsteilclen fiihrenden Wassers eingelassen usf., bis die Formen mit feinem Gips vollständig gefüllt

  Method of making plaster of paris.



     Natural gypsum stone almost always contains foreign body particles, the presence of which more or less worsens the gypsum, depending on whether they are found in larger or smaller quantities. The purpose of the present invention is to remove these foreign bodies from
 EMI1.1
 to obtain perfect plasticity.



   The procedure is carried out in the following way:
The mean of the gypsum stone obtained from the gypsum quarries in well-known
 EMI1.2
 is allowed to run into basins, where the suspended gypsum particles are deposited in suitable molds. After the plaster is completely deposited, the me. Higher or less clarified water is drained from the basins and a new amount of flowing water is poured in, etc., until the molds are completely filled with fine plaster
