 der Temperatur. 



   Mit der beschriebenen Bauart kann schon bei mässiger Drehzahl des Topfes eine   Läuterung   von glasartigen Massen auf wirtschaftlichere Art als bisher erzielt werden, da man mit weit niedrigeren Temperaturen auskommt. Die Güte der Glasmasse wird verbessert, da die schädlichen Einflüsse der bisher angewendeten hohen Temperaturen auf die Zusammensetzung und die Eigenschaften des fertigen Glases wegfallen.

 the temperature.



   With the described design, refining of vitreous masses can be achieved in a more economical way than before, even at a moderate speed of the pot, since far lower temperatures are required. The quality of the glass mass is improved, since the harmful effects of the high temperatures previously used on the composition and properties of the finished glass are eliminated.



   PATENT CLAIMS:
 EMI2.2
 vitreous mass is heated to a temperature below the usual refining temperature at which it still has sufficient tack and is then placed under centrifugal force, whereby the enclosed gas bubbles are expelled.

Claims

2. Apparatus for carrying out the method according to claim 1, characterized by a pot designed as a centrifuge which has an upper inlet opening formed by a constriction and EMI2.3 lichen.

3. Device according to claim 2, characterized in that the pot is provided with a heating device to maintain a temperature that is as constant as possible.

4. Apparatus according to claim 2, characterized in that the pot has a conical shape.

5. Apparatus according to claim 2, characterized in that the pot rests with a ring (b) on rollers (e), at least one of which is driven.

6. The device according to claim 2, characterized in that the pot for receiving the vitreous mass is provided with a cavity (e) of frustoconical cross-section.

7. Device according to claims 2 and 6, characterized in that the wall of the Pot is provided with approximately vertical channels (f) starting from the bottom of the cavity (6), which unite to form a central channel (fl) which opens into a drainage line (g).

8. The device according to claim 7, characterized in that the drain line is formed by a replaceable pipe.

9. Device according to claims 2 and 3, characterized in that in the wall of the pot channels (h) for passage. of heating gases are provided which open on both sides into chambers of the housing to which the inflow and outflow line (i, k) for the gases is connected. EMI2.4
