   Die Zufügung des Ammoniaks in Gasform, oder in wässeriger Lösung erfolgt am besten unter   Einschaltung eines Rührwerkes,   das zu dem Behufe hohl hergestellt wird, sodass das Ammoniak während des Rührens aus Löchern, die in den   Rührarmen angebracht sind, aus-   treten kann. 



   Das erhaltene Produkt   muss,   wie bereits oben erwähnt, zur Entfernung des entstandenen Ammoniumsulfates gewaschen werden. Es wird dann bei   800   C getrocknet und stellt ein ganz   vorzügliches, amorphes, wasserhaltiges Pigment für Ölfarben   dar. Man   erhält   mittelt desselben   tadellose glänzende   Anstriche, die sich nicht annähernd so schnell an der Luft verändern, wie die aus Bleiweiss (basischem Karbonat) hergestellten.

   The addition of ammonia in gaseous form or in aqueous solution is best done with the involvement of a stirrer, which is made hollow so that the ammonia can emerge from holes made in the stirring arms while stirring.



   As already mentioned above, the product obtained must be washed to remove the ammonium sulfate formed. It is then dried at 800 C and is an excellent, amorphous, water-containing pigment for oil paints. The result is flawless glossy paints that do not change nearly as quickly in the air as those made from white lead (basic carbonate).
