Description
Verfahren zur gleichzeitigen Entwicklung mehrerer Farben in Emails und Glasuren Wenn man Emails und Glasuren in verschiedenen Farben oder Farbtönen herstellen will, so ist es im allgemeinen nötig, verschiedene einheitlich gefärbte Emailmassen nacheinander aufzubringen und jeweils zwischendurch zu brennen.Process for the simultaneous development of several colors in emails and glazes When you have enamels and glazes of different colors or shades If you want to produce, it is generally necessary to use different uniformly colored Apply enamel masses one after the other and burn them in between.
Es ist auch ein Verfahren zum Herstellen gefleckter und marmorierter Emails in einem Brand bekannt, nach dem die verschiedenen Farbtöne durch Wechselwirkung von nachträglich aufgestreuter Soda mit Metallsalzen entstehen, die dem Email zugesetzt werden.It is also a method of making speckled and marbled ones Enamels known in a fire, after which the different shades of color by interaction from subsequently sprinkled soda with metal salts, which are added to the enamel will.
Demgegenüber werden gemäß der vorliegenden Erfindung mehrere Farben oder Farbtöne nebekieinander durch einen einzigen Brand in Emails und Glasuren dadurch ent wickelt, daß man bei Verwendung einer borfreien oder borarmen Email-oder Glasurmasse, .die eine Cadmiumfarbe enthält, auf diese Masse vor dem Brennen nur stellenweise Schwefel, schwefelabgebende Mittel, Sulfide, ,geringe Mengen von Borverbindungen oder Mischungen dieser Stoffe aufbringt. Beim Brennen werden die Cadmiumfarben an den Stellen, wo sie nicht mit den genannten Stoffen behandelt sind, zerstört, während sie an den anderen Stellen in orange, hellroten und dunkelroten Tönen erhalten bleiben. Es entstehen auf diese Weise Zeichnungen, Muster, Beschriftungen u. dgl. in den genannten Farbtönen auf dunklem Grund. Bei Anwesenheit anderer Farbkörper können auch andere Farben oder Farbtöne erzeugt werden.On the other hand, according to the present invention, there are multiple colors or color tones next to each other through a single fire in enamels and glazes developed that when using a boron-free or low-boron enamel or glaze mass, .that contains a cadmium paint, only in places on this mass before firing Sulfur, sulfur-releasing agents, sulfides,, small amounts of boron compounds or mixtures of these substances. When burning, the cadmium colors will turn on the places where they have not been treated with the substances mentioned, destroyed while they are retained in the other places in orange, light red and dark red tones. In this way, drawings, samples, labels and the like are created in the named shades on a dark background. In the presence of other color bodies can other colors or shades can also be produced.
Als Mittel, um die Zerstörung der Cadmiumfarben stellenweise zu verhindern, komrnen außer Schwefel in Betracht schwefelabgebende Verbindungen oder Sulfide, wie "l.'hiosulfate, Alkalisulfide und -polysulfide, Zinksulfid u. d-1. Von Barverbindungen seien Borsäure und Borax genannt. Diese Behandlungsmittel werden zweckmäßig in Form wäßriger Lösungen auf die mit der gefärbten Emailschicht überzogenen Gegenstände aufgestrichen.As a means to prevent the destruction of the cadmium colors in places, In addition to sulfur, sulfur-releasing compounds or sulfides can also be considered, such as "1.'hiosulphates, alkali sulphides and polysulphides, zinc sulphide and d-1. Of bar compounds boric acid and borax are mentioned. These treatment agents will expediently in the form of aqueous solutions on those coated with the colored enamel layer Objects painted on.
Auf diese Weise kann man auf sehr einfache Ait die verschiedenartigsten Farbwirkungen in Emails und Glasuren erzielen. Beispiel Einem borfreien Transparentemail setzt man die übliche Menge eines Farbkörpers zu, der aus einem Cadmiumrot und einem blauen Farbkörper bestehen möge. Man mahlt die Fritte mit dem üblichen Tonzusatz und bringt das Email auf ein grundemailliertes Blech auf. Nach dem Trocknen bestreicht man einige Stellen mit einer Borsäurelösung, andere mit einer Natriumsuitiellösung ; die Lösungen können beispielsweise etixa too@oig sein. Beim Brennen wird an den nicht behandelten Stellen die Cadmiumfarbe durch den Einfluß des borfreien Email zerstört, so daß die blaue Farbe hervortritt. An den behandelten Stellen dagegen entwickelt sich ein blaustichiges Rot. Dabei sind die mit Borsäure- bzw. Sulfidlösungen behandelten Stellen noch unter sich verschieden getönt.In this way one can very simply ait the most diverse Achieve color effects in enamels and glazes. Example of a boron-free transparent enamel one adds the usual amount of a color solid, consisting of a cadmium red and a blue color body may exist. The frit is ground with the usual clay additive and applies the enamel to a basic enamelled sheet. Brushed after drying some places with a solution of boric acid, others with a solution of sodium ; the solutions can be etixa too @ oig, for example. When burning, the cadmium color due to the influence of the boron-free enamel on untreated areas destroyed so that the blue color emerges. On the other hand, in the treated areas A bluish red develops. Those with boric acid or sulfide solutions treated areas still differently tinted under each other.
