Description

There is a method of decorating a kerch; Mick or metal products, by applying a surface layer of a paint from a solution of gummy-bay, a tragant, etc., of lipi-forming substances and a drying net that affects the distribution of the paint coating. Applicants suggest using a layer of an underlying paint, mainly in the form of a chandelier, as a covering layer of a substance with a large surface tension. To enhance the surface tension, ethylene glycol, chloral hydrate and the like are added to glycerin; colloidal substances (gum arabic, gelatin, tragant), as well as cane sugar, can be added to the glycerin solution to change the size of the resulting mesh.

According to the present invention, a layer of paint is first applied to the objects to be decorated, preferably from those known in the ceramic industry under the name "Luster of paint solutions." Such chandeliers can consist of metals, such as: gold, silver, etc., of metal oxides, such as nickel oxides, copper, cobalt, or other suitable metal compounds, which are dissolved together with tar in oils. (turpentine oil, lavender oil, etc.). A coat of such substances or mixtures which, when heated, have a greater surface tension than the underlying soft or softened layer of paint, is then applied to the layer of paint, so that this cover can be pulled out to form patterns in the form of nets; lines or veins; Such a pattern has the spbbing to displace the underlying paint, so that when fired, the object is obtained due to the aforementioned ffSSa.

and forcing out paint, for example, a network of white veins, while gaps retain the color of paint. For coating use, such substances that are liquid at a temperature {softening stage of the mixture of resin with oil of a chandelier and which have a higher surface tension, are softer or softer underlying layer; such substances include, for example, glycerin, ethylene-glincole, chloral hydrate, etc. They can be used, for example, in aqueous solution or diluted with water and alcohol, etc. To obtain a good film on a colored background, to it is good to add to the glycerin solution also colloidal substances, such as gum arabic, gelatin, tragant, etc. Finally, you can add substances such as cane sugar to the solution. It turned out, for example, that by adding sugar, to change the nature and size of the product obtained: for example, solution, glycerol and gum arabic, which, when used according to the invention, gives a mesh with comparative |) BUT in small loops, while adding the proper amount of cane Sugar gives a larger loop.

Example 1.1 The said chandeliers are applied in the usual way to a ceramic object, for example, to glazed porcelain. After the dyestrum has precisely dried, it is applied to a dry silt, if necessary, a mixture of IZ-40 g of gum arabic, 40 glycerin, 100 g of sugar, 300 g of alcohol and 520 g on an even softer layer of chandelier.

-waters by brush reddumb by immersion, spraying, etc. in ways. After the cover has been applied, the item is left standing for a while and then subjected to baking firing.

When heated on the uniformly

Irregular, more or less broad lines in the form of grids, in which the dye of the chandelier has largely disappeared, and which therefore have the asbestos M iiBeTOM ceramic object, are formed on the painted surface. When the cover is tightened in, the grid of the lying lower layer below the chandelier is more or less: removed from lines or veins; however, it does not rise above the surface of the ceramic object and does not burn when

- 2 firing, as is the case with existing methods. On the baked piece, patterns in the form of grids, honeycombs, etc. are obtained, with the individual loops and honeycombs having an irregular and peculiar shape. The lines or veins have the natural color of the ceramic surface, while the areas between the lines are the color of the chandelier; Since, when the cover is dried, it more or less carries icpacKy with it, the color of the fields turns out to be uneven, which causes completely new decorative effects.

The proposed method can be carried out by if in such a way that dyes other than the dye from the bottom of the chandelier layer are added to the solutions and mixtures as well: for example, colored salts that give color: oxides. Using such solutions, you can get the lines and veins otherwise colored than chandeliers. In addition, on the border of various sections, it was then to get peculiar stern colors.

When applying dyes containing dyes, one can also act in such a way that they take primers for dye-free mixtures of Smol with oils; in this case, the finished object shows colored lines and veins against the background of the natural color of the object, and peculiar and characteristic lines are obtained, especially very thin lines and veins.

In order to realize the proposed procedure, it is also possible to use so-called ceramic melting; ny paints containing, HanpitMep, metal oxides in combination with smooth or mixed substances (lead oxide, boron, bismuth, etc.). When using such paints, the grids and lines of the pattern are not colorless, they form a darker pattern on a less colored background. Firing, for example, a suitable red melting paint on an object of white porcelain, can be obtained such a pattern in which the floor between the part. the lines and veins turn out bright red in the OTTeHKiax ratios, while the lines and veins turn out to be dark brown and temzeleny. You can, if desired, to achieve

 and the fact that the lines and snares were multi-colored, at what “lacTb they can also have the natural color of the ceramic object. You can also mix different paints, for example, fe combi, lacquer with chandeliers a.

EXAMPLE 2. On the porcelain surface, a layer of sales of blue paint was applied by sprinkling, rubbing it with 50% of thick dye. As soon as this layer dries,

A layer containing 14 parts of glycerin, 12 parts of gum arabic, 5 parts of sugar, 20 parts of alcohol, 49 parts of water — a total of 100 parts.

To obtain a pattern, you burn the object in the usual way in a muffle.

-, the furnace.

The decoration of objects with a metallic surface is made as aiQ, as well as ceramic objects. Here too, chandeliers containing metals, such as: lotto, can be used as a paint; and silver, or metal compounds, for example nickel-copper, or others containing metallic compounds, as well as metallic melting paints containing metal oxides in combination with smooth or bonding substances.

In order to achieve a more rapid combustion of the soil containing the paint, it is possible to BL known cases to make up the soil with an admixture of slightly burning or SPO. Combustion of substances. These substances (e.g., nitrocellulose) may themselves be surrounded by a harlister la1 (: a. Such a measure is rejected expedient if the decorated objects have a comparatively low melting point and must therefore be burned at low temperatures. The decoration can be affected in different directions by appropriate preparation of metals or metal objects, for example, if you first polish the surface or etch it, or prepare it thermally in an appropriate atmosphere, or subject it to another under nym processes.

 The present invention makes it possible to obtain unique patterns on metal surfaces; the metal layers deposited on the metal also serve to protect the metal against oxide.

laziness or fret, for example, air, humidity, etc.

Froze The surface of the hydraulic object is first polished. After that, a layer of the sales chandelier „Craqueiier-Purpur“ is applied to it in the usual way. As soon as the chandeliers are completely dry, the cover of the next solution is applied to the layer of soil on the background with a brush;

100 pieces.

The item treated in this way is burned in a muffle furnace. The resulting pattern consists of light colored veins, showing the natural color of aluminum, while the floor between the lines is round or oblong and colored in various shades of red.

Example 4. A brass object is covered with a layer of commercial ceramic „royal paint”, to which 50% of thick oil is added. This layer of paint is dried and then a cover having the same composition as in example 1 is applied to it. To burn the paint, the latent object is then subjected to the burning process, moreover, if it is done in an already hot oven, then for the proposed method decorating it is advisable to pre-heat the object.

The subject of the patent.
