  Verfahren zum Brennen von Gips. 



   Vorliegende Erfindung betrifft ein Verfahren, um gleichzeitig ungleich dichte Gips stücke verschiedener Herkunft durch Brennen regelmässig abbindefällig zu machen. 



     I.   s sind viele Arten von Verfahren bekannt, um sowohl die Naturgipssteine als wie die aus ihnen erzeugten Gipsgüusse durch Brennen abbindefähig zu machen und dabei je nach Wahl des Rohmateriales und Durchführung des Brennprozesses gewisse für die feinere Verarbeitung wichtige   Spezialeigenschaften   des Brennproduktes zu erzielen.

   Alle diese Vorfahren zur Erzeugung eines gleichmässigen gebrannten guten Stuckgipses bzw. zur Herstellung bestimmter guter festor Gipsgüsse verlangen ein regelmässiges, gleich dichtes, durchwegs gleich hohen Gehalt an chemisch gebundenem Wasser aufweisendes Gipsrohmaterial, was von grossem Nachteil ist, da man in der Fabrikation von   Stückgips   und insbesonders von dessen Spezialabarten auch dadurch an das Verarbeiten gewisser Sorten Rohmaterialien, somit auch an bestimmte Bezugsquellen, Fundorte, lieferbare Mengen usw, gebunden ist. 



   Vorliegende Erfindung behebt diese Mängel, indem sie es gestattet, alle ungleich dichten   Gipssorten   in einem   Erhitzungsprozess   gleichmässig zu entwässern, und zwar wurde gefunden, dass man die ungleich dichten Gipsstücke zur gleichmässigen Entwässerung in ein und demselben Erhitzungsvorgang auf ungleiche Grösse bringen muss, d. h. man muss die im Raumgewicht schwereren, dichteren und weniger chemisch gebundenes Wasser ent-   haltenden Gipsstücku kleinor,   die grösseren, in Raumgewicht leichteren und mehr chemisch

  Method of firing plaster of paris.



   The present invention relates to a method to simultaneously make unevenly dense plaster pieces of different origin by firing regularly to set.



     There are many types of processes known to make both the natural gypsum stones and the gypsum casts made from them capable of setting by firing and, depending on the choice of raw material and implementation of the firing process, to achieve certain special properties of the fired product that are important for the finer processing.

   All these ancestors for the production of a uniformly fired good stucco plaster or for the production of certain good festor plaster casts require a regular, equally dense, consistently high content of chemically bound water containing gypsum raw material, which is a great disadvantage, since one in the production of lump of plaster and In particular, the special varieties of which are bound to the processing of certain types of raw materials, thus also to certain sources of supply, locations, available quantities, etc.



   The present invention overcomes these deficiencies by allowing all unevenly dense types of plaster to be dewatered evenly in one heating process, and it has been found that the unevenly dense pieces of plaster must be unevenly sized for even dewatering in one and the same heating process, i.e. H. The pieces of plaster, which are heavier, more dense and contain less chemically bound water, must be smaller, the larger ones, lighter in density and more chemically
