    Staub-und Schwärzmittel   für Gussformen. 



   Staub- und Schwärzmittel für Gussformen, welche Mittel aus einem pulverförmigen Gemengo von Quarz und Kohle bestehen, sind bekannt. Die Erfindung bezieht sich nun auf die Verwendung von Braunstein als Zusatz zu diesem Quarz-Kohlenpulver in solcher Menge, dass eine Verbindung des Braunsteines mit dem Eisen zu einem magnetischen

    Dust and blackening agents for casting molds.



   Dust and blackening agents for casting molds, which agents consist of a powdery mixture of quartz and coal, are known. The invention now relates to the use of manganese dioxide as an additive to this quartz-carbon powder in such an amount that a compound of the manganese dioxide with the iron forms a magnetic one
 EMI1.1
 stone to the quartz carbon powder this is to serve as a substitute for graphite for foundry purposes.
 EMI1.2
 Dust and blackening agents are generated, which primarily protect the shape itself during casting and prevent the molding material from sticking to the castings.



   As an example of the composition of the powdered and well mixed ingredients
 EMI1.3
 5 parts by weight of manganese dioxide.
