Kontakt zwischenFixativ und dem eigentlichen Emailkorn. Dasselbe gilt auch für Ton. Die üblichen   wasserlöslichen Stellsalze, wie Natriumnitrit   und Soda, sollten aus diesem Grunde durch unlösliche Ver- bindungen mit entsprechender Stellwirkung ersetzt werden. Als brauchbar haben sich Lithiumphosphat und Lithiumcarbonat erwiesen. Auch sollte der Tonanteil möglichst gering gehalten und möglichst magere Tone verwendet werden. 



   Von erheblicher Bedeutung ist ausserdem die Korngrössenverteilung des Emails. Grundsätzlich ist eine möglichst grobe Emailmahlung mit einer einheitlichen Korngrössenverteilung zweckmässig, weil sie die abzudeckende Oberfläche vermindert.

Contact between fixative and the actual enamel grain. The same goes for sound. For this reason, the usual water-soluble setting salts such as sodium nitrite and soda should be replaced by insoluble compounds with a corresponding setting effect. Lithium phosphate and lithium carbonate have proven to be useful. The clay content should also be kept as low as possible and lean clays should be used.



   The grain size distribution of the enamel is also of considerable importance. Basically, it is advisable to grind the enamel as coarsely as possible with a uniform grain size distribution, because it reduces the surface to be covered.

Claims

PATENT CLAIM: A method for decorative enamelling of household appliances, preferably ovens, by means of a plastic film provided with embedded enamel paints, which is applied to the part to be decorated and provided with a carrier enamel layer and subjected to a decorative firing, characterized in that on an unfired and already dried carrier enamel layer before the application Plastic film an organic binder solution such as an aqueous suspension of methyl cellulose, polyvinyl acetate and polyethylene glycols is sprayed on and then dried, in particular the enamel slip used for the carrier enamel being practically insoluble compounds with a corresponding positioning effect, such as lithium phosphate and lithium carbonate,

and / or contains as little and as lean clays as possible and / or an enamel slip with a coarse grinding and a uniform grain size distribution is used.
