Description

The invention relates to a method for producing a glass object.

Nowadays, glass objects come in a wide variety of shapes and sizes various uses. Examples include glass vessels such as goblets, cups, carafes etc. or glass vases and the like chen. Glass plates or glass plates are also known. Glass objects are coming also z. B. in the form of jewelry or ornaments. The area of application and there are no limits to creativity here.

A central feature of a glass object is inevitably its appearance, that is, its design, which has a direct effect on the buyer, user or wearer, and that should appeal to this. In addition to the possibility of as already described It is known to have a wide variety of shapes and colors to fuse colored glasses to form the glass object. Colored, i.e. colored glasses have always been known. So that's how it is z. B. possible to a glass goblet with a colored collar at the transition to the stem provided or jewelry in different colors and colors to produce compilations etc. Although this is a considerable advantage Color palette and with it offer considerable variation and design options the expert, however, only on the use of colored glasses instructed on color design.

DE 15 96 826 C3 describes a method for producing iridescent glasses known in which a vitreous body with silver salt and a sublimable metal connection treated with a reduction and then with glass is stabbed. DE 32 04 959 C1 describes a method for generating light-scattering and structured surfaces in an intermediate glass layer, at which is sandblasted and pierced with liquid glass, whereby a Bubble curtain is generated, which can be colored with metal oxides.  

Furthermore, it is known from DE 39 08 121 A1, a glass section with a De Kor made of ceramic paint and with another layer of glass as a coat to cover. EP 0 086 242 A1 also describes the possibility of using a Glass pail a color print from enamel colors or precious metals with multi-colored to apply complicated motifs and with a second layer of glass as a coat to pierce glass.

According to DE 30 17 348 A1, a color is used to produce blown flashed glass manterl manufactured, combined with a glass item to be blown and ge in shape blow, the glass item as a drop on the preheated color coat brought and pressed in a mold to a multi-layer compact becomes. Finally, DE 885 301 B states that between two ver melting flat glass plates an intermediate layer of enamel-like river mit tel can be introduced. Furthermore, DE 23 14 622 B2 is a more layer plate known, with a given between the two glass plates if colored granulate coating from z. B. inorganic glass material is arranged. A multilayer glass plate is also known from DE 29 11 591 A1, where when recesses are provided in a first glass plate, which with given if colored glass granules are filled in, another glass plate arranged and fused with the first glass plate or with a casting melted glass is coated. Ultimately, DE 200 16 616 U1 Multilayer insulating glass is known, which is equipped afterglow, each but the luminescent layer is not on a glass surface, but on the frame its surface facing between the panes in the interior introduced.

The invention is therefore based on the problem of specifying a possibility to give a glass object an idiosyncratic colored appearance.

To solve this problem is a method of manufacturing a glass object provided according to the invention that on a first glass section a layer of powdery fluorescent or phosphorescent Luminous pigments is applied, after which a covering the luminescent pigment layer  second glass section is applied to the first glass section which ver with the first glass section including the luminescent pigment layer is melted, after applying the outer one, a luminous pigment layer enclosing glass section or after fusing the glass sections a shape and / or design is carried out.

The method according to the invention enables a layer to be melted luminescent luminous pigments in the glass object, where a first ter glass section is produced, on which the luminous pigment layer is then applied is brought. A second glass is then placed on this first glass section section applied, after which both glass sections melted together are so that the luminous pigment layer in the then quasi one-piece Glass object is melted down. With the luminescent pigment layer, extremely idiosyncratic lighting or afterglow effects can be achieved that the glass lend an extremely idiosyncratic appearance when the luminous pigment layer afterglow. Any organic or inorganic long-afterglow pigments, usually by short-wave or boring radiation can be induced to afterglow. Such pigments are known with a wide variety of fluorescent colors and enable the To give glass objects a very idiosyncratic appearance. Be used can these luminescent pigments with any glass object, e.g. B. at Drinking glasses in the appropriate darkness after previous suggestion afterglow in the respective color. The afterglow effect achieved in this way is very striking and interesting for the viewer, for example, to think about use of such drinking vessels in the catering sector, e.g. B. in discos and the like, where there is some dim light anyway, and where the Afterglow pigments can develop their special effect. Also a ver application in the home or for jewelry, which then at given darkness is also visually conspicuous, is conceivable. The As with conventional glass objects, the possible uses are unlimited.

According to a first alternative of the invention, it can be provided that the first Glass section is a glass item made of viscous glass, on which the luminous pigment layer  is applied, and the still viscous state with a the second glass section forming glass items from viscous glass will. So here are two still viscous glass items under inclusion the luminous pigment layer fused together. This procedure excl attitude offers z. B. in the manufacture of manual or machine Herge made blown or pressed glass objects such. B. goblet glasses, Drinking cups, juice or wine carafes or larger vases.

It is possible to provide only one luminescent pigment layer or to melt, i.e. ultimately ver the glass object from two together to form molten glass sections. In addition, it goes without saying it is also conceivable to apply at least one further layer of luminous pigment and this with at least one additional covering glass section from one to pierce viscous glass items. That means the glass object can also have a multi-layer structure, ie two or more layers of luminous pigment have, each pierced with a glass section covering them are. Of course, the inside glass section will be as possible keep thin so that the entire wall thickness of the glass object is not too large to be let. However, this is ultimately from the glass object to be manufactured dependent.

The luminous pigment layer can be applied manually, on the one hand, what expediently by simply immersing the viscous glass batch, which is to be coated with the luminous pigment layer, into the powdered luminous pigment ment can be done. There is also an inflation, brushing or printing conceivable. Obviously, any method can be used that Applying the luminous pigment layer as long as this process is safe and the application meets the requirements with sufficient liability of the Enable luminous pigments. As an alternative to this, it is also conceivable for the luminous pig elements to be applied by machine, primarily with machine-made glass items such as B. automatically manufactured pressed glasses, where z. B. a ma rapid controlled immersion of the glass batch in the pigment bed or a mechanically controlled inflation takes place.  

In a further development of the inventive concept it can be provided that the second and / or the other glass item or items, each one below include the luminescent pigment layer, by pressing, optionally under simultaneous shaping is or will be applied. Alternatively, it is natural Lich also conceivable to manually apply each glass item, which is mainly at handcrafted items will be the case.

An alternative manufacturing method to using viscous glass items in contrast, provides that the first glass section is preferably a flat one Glass plate is applied to the light pigment layer when cold and on the one forming the second glass section, essentially like the first shaped cold glass plate is placed, after which both glass plates he warms and fuses together, including the luminescent pigment layer become.

This process design according to the invention enables the production of Flat glass objects, which can ultimately have any size, depending on the size of the used and stacked glass plates. Here too However, the basic principle is the same, namely that a layer of luminous pigment is melted between the two glass plates, the glass plates will So fused together at the interface and the luminescent pigments into the Melted glass melt. In contrast to the procedure described Reensausbildung, where the hot, viscous glass items are used den, this process variant starts from cold glass plates, which as usual Liche flat glasses were usually made by machine. On a lower one The luminous pigment layer is applied to the glass plate, after which a second Glass plate is placed and then the fusion is carried out becomes.

Here, too, it is of course conceivable to get the best multi-layer panel composite consisting of more than two cold glass plates with between two glass plates each to form enclosed luminous pigment layers, whereby here one first  the entire panel composite is piled up and then heated, see above that the individual plates are fused together.

As described, this process variant enables large-area production ger panel dressings with at least one melted fluorescent layer. Out These large glass objects, it is possible in any shape small Saw out glass objects with which subsequently z. B. a mosaic or the same or any jewelry can be put together. Of course, there is also the option of differently colored large areas to produce glass objects so that the glass objects can be processed the possibility is given to different colored glass jars items z. B. to assemble to form the mosaic. Here too are the ultimate application and processing of the large glass counter there would be no limits. Of course there is also the possibility speed, these large glass objects themselves z. B. for wall decoration to use.

As already described, there are luminous pigments with different colors known. However, in order to be able to further increase the color variation possibility be provided that to form the one or more luminous pigment layers of luminous pigments are used in the form of a pigment mixture afterglow in different colors. That is, you can go to education Luminous pigment layer a pigment mixture of differently colored luminescent pigments, e.g. B. from green and orange luminescent pigments, so too an afterglow mixed color. Alternatively, of course, there is also the possibility of using glass with multiple layers of luminous pigment to form different layers of luminescent pigments or mixtures, so that the individual layers of luminous pigment come in different colors to shine. Those skilled in the art are familiar with the color and mixture variations there are no limits to the possibilities.

In a further development of the inventive concept it can be provided that according to the Application of the last outer one, including a layer of luminous pigment  Glass section or after fusing the glass sections to form and / or design this deformed itself and / or with another glass object is connected. So it's not just a finished glass object finished object to look at, but any glass object, which is either a finished end product or quasi an intermediate product or represents a semi-finished product. So it is easily conceivable to turn one on molten light pigment layer glass object with a white to connect another glass object. The important thing here is that the two are closed connecting glass objects can be melted together without problems, that is, the respective expansion coefficient must largely agree men. The glass objects can be processed in the cold or hot condition. In the hot state, for. B. the glass items for Formation of the final glass object processed further, e.g. B. in the Her position of a goblet, where the upper glass goblet is first blown which then z. B. in the area of the chalice bottom, the luminous pigment layer is applied and pierced, after which on the still hot second glass post that was pierced, a stem is melted. Here too are the There are no limits to those skilled in the art. Cold processing is e.g. B. possible with the flat glass objects already described.

As already stated, the glass object itself can be used as a counterpart Tand, especially in the form of a liquid vessel. Alternatively, you can the glass object also a semi-finished product, especially in Be in the form of a rod, rod, peg or plate. It is conceivable, the glass jar made with the melted luminous pigment layer form objects in the form of a rod, which as a handle for z. B. a goblet serves and is melted onto the blown upper chalice. It is next to it it is also conceivable to start such a rod or rod at its tip melt and z. B. melt as a border on a glass plate or as a ring bunch on a goblet. There are no limits to the possible uses.

In addition to the method itself, the invention further relates to a glass object, which was produced in the manner described.
