  Verfahren zur Herstellung poröser   Baukörper od. dgl.   aus Gips. 



   Den Gegenstand vorliegender Erfindung bildet eine weitere Ausgestaltung des durch das Patent Nr. 131866 geschützten Verfahrens, nach welchem der abzubindenden Masse gasentwickelnde Stoffe beigesetzt werden, die durch Entwicklung des Gases ein Aufblähen der Masse bewirken, wobei die sich entwickelnden Gasbläschen durch Fischleim in der Gipsmasse zurückgehalten werden. 



   Gemäss vorliegender weiterer Ausgestaltung wird an Stelle von Fischleim ein   künstlich   hergestellter Leim verwendet. Dieser besteht aus Knochen, Lederleim od. dgl., welchem beispielsweise durch entsprechend Zusätze von Säuren oder Salzen die Gelatinierfähigkeit entzogen ist, so dass er sich in kaltem Wasser   löst.   



   In gleicher Weise könnte auch ein sonstiger im kalten Wasser   löslicher,   ein Platzen der Gasblasen verhindernder Stoff verwendet werden. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the production of porous structures or the like from plaster of paris.



   The subject of the present invention is a further embodiment of the process protected by patent no. 131866, according to which gas-evolving substances are added to the mass to be set, which cause the mass to expand through development of the gas, with the developing gas bubbles being retained by isinglass in the gypsum mass will.



   According to the present further embodiment, an artificially produced glue is used instead of isinglass. This consists of bones, leather glue or the like, which is deprived of its ability to gelatinize, for example by adding acids or salts, so that it dissolves in cold water.



   In the same way, another substance which is soluble in cold water and prevents the gas bubbles from bursting could also be used.

** WARNING ** End of DESC field may overlap beginning of CLMS **.
