Description

The present invention relates to methods for applying an enamel coating for the purpose of forming a pattern, and can be used to create jewelry and souvenir products.

BACKGROUND

From the existing level of technology there is a known method of art painting on metal or enamel soil (Brepol E. Art enameling / Translated from German by I.V. Kuznetsova; Ed. L.Z. Zasukhina / E. Brepol. - L.: Engineering, Leningrad , Dep., 1986. - pp. 84-85), which involves applying to the metal surface of the decorated product, or on the enamel primer laid on it the outline of the pattern, by scratching it. The disadvantage of this method is the complexity and the complexity of preparing the surface of the product for painting, as well as the need before applying enamel to degrease the decorated product by burning with a gas flame. Moreover, under the influence of high temperatures, the metal surface of the product or a layer of soil enamel can be deformed or undergo irreversible damage, which invalidates the decorative and consumer properties of the decorated product and makes it impossible to use it further. Another disadvantage of this method is the need for the user to interact with an open gas flame, which can lead to burns or ignition of the workplace. Another disadvantage of the known solution is the use of copper as the basis material of the decorated product, which significantly reduces the consumer properties of the product in the manufacture of jewelry. In addition, the disadvantage of the known solution is the inability to perform painting with the effect of volume (stereoscopy).

Also known from the prior art is the technology of painting on enamel (Technique of artistic enamel, stamping and forging. A.V. Flerov, M.T. Demina, A.N. Elizarov, Yu.A. Shemanov - M., 1986, § 5 ) involving the execution of painting in three stages: drawing a contour of the drawing on the product, painting, firing. A disadvantage of the known solution is the impossibility of painting with the effect of volume (stereoscopy) (http://electro-shema.ru/files/texnika-xydozhestvennoi-emali-chekanki-kovki.pdf).

SUMMARY OF THE INVENTION

The technical task of the claimed invention is the development of such a method of applying a decorative enamel coating, which would allow to perform artistic painting with the effect of stereoscopy. Another objective of the claimed solution is to simplify the process of applying a decorative enamel coating. The objectives of the claimed invention also include improving the safety of the user during the application of decorative enamel coatings. And also the stated task is to expand the enameling methods and increase the consumer properties of products with a decorative enamel coating.

The claimed technical task - "the development of such a method of applying a decorative enamel coating that would allow performing artistic painting with the effect of stereoscopy" is achieved by performing artistic painting in two stages, with an intermediate layer of transparent enamel applied to the decorated product. So, a decorated product made of gold or silver, having a concave surface and sides, is subjected to preliminary firing, after which a chemical reagent is applied to the surface of the product, which purifies the metal from oxides formed during heating. A counter-enamel layer is applied to the cleaned metal base, after which the product is calcined in a muffle furnace at a temperature sufficient to melt the counter-enamel. Counter-enamel improves the adhesion of the enamel soil to the metal base, and also prevents the penetration of oxides formed in the enamel product firing process into the enamel soil. One layer of plain enamel soil is applied to the formed surface, after which the decorated product is fired in a muffle furnace. In a particular case, the enamel primer may consist of several enamels of various colors. After firing, an artistic painting is applied to the item to be decorated. The painting is applied without using a stencil or a previously transferred outline of the picture. This method of applying murals avoids damage to soil enamel. After applying art painting, the decorated product is fired in a muffle furnace. After that, a layer of a transparent flux having an expansion coefficient equal to or close to the expansion coefficient of the metal from which the decorated product is made is applied to the painted surface and fired until complete melting and the formation of a uniform transparent surface. In a particular case, transparent enamel is applied to the painted surface, having an expansion coefficient equal to or close to the expansion coefficient of the metal from which the decorated product is made, after which the product is also fired. The color of the applied transparent enamel is determined by the artistic design of the item to be decorated. After firing, an artistic painting is applied to the cooled layer of transparent flux, repeating the pattern already applied, after which the final firing of the decorated product is carried out. The claimed stereoscopic effect is achieved by making the surface of the decorated product concave, as well as by applying art painting in two layers, with an intermediate application of a layer of transparent flux.

The claimed technical task - "simplifying the process of applying decorative enamel coatings" is achieved by eliminating the process of transferring the contour of the picture to enamel soil in the process of art painting of the decorated product.

The claimed technical task - "improving the safety of the user in the process of applying a decorative enamel coating" is achieved by performing the process of applying a decorative enamel coating without contact of the user with an open gas flame.

The claimed technical task - "the expansion of enameling methods and increase the consumer properties of products with decorative enamel coating" is achieved by developing a method of applying a decorative enamel coating with the effect of stereoscopy. At the same time, due to the application of art painting without a stencil or a contour previously transferred to the decorated surface, each decorated product will have its own characteristic visual features and exist in only one copy.

DETAILED DESCRIPTION OF THE INVENTION

The method of applying a decorative enamel coating with the effect of stereoscopy includes preparing a metal base, applying enamel, applying enamel soil, performing the first layer of art painting, applying a layer of transparent flux, performing a second layer of art painting that repeats the previously applied drawing.

A decorated product made of gold or silver, having a concave surface and sides, is subjected to preliminary firing, after which a chemical reagent is applied to the surface of the product, which purifies the metal from oxides formed during the heating process. A counter-enamel layer is applied to the cleaned metal base, after which the product is calcined in a muffle furnace at a temperature sufficient to melt the counter-enamel. One layer of plain enamel soil is applied to the formed surface, after which the decorated product is fired in a muffle furnace. In a particular case, the enamel primer may consist of several enamels of various colors. After firing, an artistic painting is applied to the item to be decorated. The painting is applied without using a stencil or a previously transferred outline of the picture. After applying art painting, the decorated product is fired in a muffle furnace. After that, a layer of transparent flux is applied to the painted surface and fired until complete melting and the formation of a uniform transparent surface. In a particular case, transparent enamel is applied to the painted surface, after which the product is also fired. After firing, an artistic painting is applied to the cooled layer of transparent flux, repeating the pattern already applied, after which the final firing of the decorated product is carried out.
