Abstract

The invention relates to decorative articles and utensils made of porcelain, and to a process for decorating these articles by baking-in of noble metal and/or lustre substances using a manual procedure, by which special decorative effects are achieved.

Description

The invention relates to jewelry and commodities made of porcelain and is characterized that these items are burned by and / or luster substances are decorated.

Porcelain is mostly decorated using a stoving process, the baking temperature and, if necessary the atmosphere, whether reductive or oxidative, matters play.

The decoration is predominantly in an oxidizing atmosphere branded in, as a result color falsifications are involved to the specified colors can be prevented.

The temperature of the stoving plays a role in this Role, because of their variation certain course effects can be achieved or prevented.

The most representative are motifs as decoration of Porcelain known. These are artistically opened manually  the porcelain painted and baked, or more modern The so-called decal method is used.

All of these processes are aimed at mass production, even with small series, the motifs to repeat.

In contrast, the inventive method leads to decorating from porcelain to exclusively individual and non-repeating motifs.

The new process for decorative coating of porcelain, by means of a stoving process, using of coating substances in the form of liquid colloidal or disperse agent, based on precious metals and / or chandelier, is characterized in that one coating substances selected by pre-fire tests or their mixtures, manually on the to be decorated Porcelain applies, dries and at a temperature burns in between 700 to 900 ° C, making very special Porcelain decorations are preserved in which the noble metal character is dominant, with a Repeat the coating procedure several times the intensity of the color and the decorative effect varies can be.

Another special design of the new process rests in that to achieve special crack structures or marble effects in the decoration, after the precious metal or luster coating and an intermediate drying or after a fire, so-called craquelier or marbling solutions on the porcelain to be decorated be applied.

The innovative method lies in particular in the special and individual and non-repetitive  Design of the decorative motifs. Only by chance may be any structures from the motifs from the perceptual circle, such as animals or plants, be interpreted.

The technical progress of the new process lies in the extraordinarily high product yield, which can be settled at practically 100%.

If, for example, the decoration after the first firing should not have turned out as desired, then is it is easy to make a correction.

By re-coating the first decoration, also with chandelier and / or marbling or craquelier solution, you achieve the after another firing desired effects.

Craquelier solutions, for example, cause shaded areas Chandelier fields with mirror gloss effect and crack motif Structure.

Marbling solutions leave small white fields in the applied decoration arise, creating a marble effect results.

Another advantage of the new process is that you can the same procedure for all objects to be decorated can apply unchanged, which means no additional effort for any additional procedures.

In detail and in general, the new procedure as described below.

The white glazed porcelain objects to be decorated have to be completely clean.

For an orientation for the hue after firing preburn samples with the ones to be used will be won Precious metal or luster preparations, on the applied  Decor carrier made.

The liquid preparations are then selected and optionally mixed, manually using a soft Hair brush on the porcelain objects to be decorated painted.

The thickness of the coating is based on experience and depends on the color depth and shadow effects to be achieved and remains of artistic design reserved by the user.

The subsequent drying of the Objects in a dust-free place.

If coating only with chandeliers, the dried luster preparations, directly a craquelier or marbling solution and dried the item will.

Precious metal preparations can stand alone on the porcelain objects can be applied, or else even after drying, the chandelier preparation applied and dried.

After drying, the firing of the items becomes advantageous in an electric furnace, without affecting the atmosphere - that is oxidizing - at one temperature between 700 and 900 ° C.

After about 15 minutes burning time and cooling are the decorated objects without further treatment ready to use, unless they become still bordered.

Only if special decorative effects are achieved should be the coating procedure, especially in Sub-areas, for example using chandeliers, repeated will.

For example, so-called Polished gold or shiny platinum in a precious metal concentration  from about 10 to 30% can be applied. Silver preparations also give excellent decorations.

All shades of the entire color range come as chandeliers, as well as metallic and, for example, iris tones.

Especially jewelry and commodities made by the process of the present invention.

Let me mention in detail; Cufflinks, brooches, Rings, tie pins, bracelets, pendants, pill boxes, Ashtrays, vases and other such articles that still correspondingly in metal or other materials can be bordered.

Manufacturing examples are described below, wherein the method is of course not limited to these examples is.

example 1

On a white glazed, oval porcelain plate with the diameter lengthways, 5 cm and widthwise of 3 cm, which represents a pendant, with a Applied a mixture of chandeliers, after a pre-fire test from the shades, orange, blue and green were mixed together and an emerald green Color supplies.

After drying, Craquellier solution is applied and dried again. Then during burned in an electric oven for about 15 minutes at a fire temperature of 780 ° C.

A beautifully decorated porcelain plate is obtained with emerald green color and pronounced crack structure.

The pendant received is a valuable piece of jewelry represents.  

Example 2

A white glazed round porcelain plate from Diameter of 1.5 cm, which is a cufflink represents with a gold preparation with a Brushed hair brush and after drying Fired at 800 ° C. Burn time about 18 minutes.

After cooling, one is on the same board Color combination of different types of chandeliers in the different order sizes applied, consisting from the colors bronze, blue and black. After this A marbling solution is applied to dry dried again and then for about 20 minutes baked at 740 ° C.

After cooling you get a platinum with one gold-colored, fully covering basic tone with antique marble Brown-black tone effect.

There is a third fire after a coating with an iris tone chandelier at 780 ° C while 15 minutes, then come the colors of the previous one Brandes more to the fore, with a special one Iris effect.
