Description

 The invention relates to decorative art, namely to the manufacture of mosaic products of increased light-color expressiveness.

 Known mosaic product containing mosaic elements made of natural stone and fixed on a rigid base (RF patent 2021153 C1, CL 44 C 1/28, 1994).

 However, the execution of mosaic elements from a limited set of materials (black and white marble, lapis lazuli, larchite, gray and red granite, jasper and other minerals) limits the color scheme of the created mosaic image, and the polished surface of the mosaic elements is not decorative and expressive enough.

 Closest to the claimed mosaic product is a mosaic product containing mosaic elements fixed on a rigid base, while the mosaic elements have a polygonal plan and are connected by a binder into a regular structure (RF patent 2080008 C1, CL 44 C 1/28, 1994).

 However, the implementation of a mosaic product from the same or similar in size elements connected to a regular structure, and the need for accurate fitting of neighboring elements to each other is a rather laborious task and does not allow creating high-resolution mosaic images, which is limited by the characteristic sizes of the mosaic elements.

 The technical result achieved by the implementation of the proposed mosaic product is to provide the ability to perform mosaic elements of arbitrary shape and size from a glassy material, in particular enamel, and to eliminate the operation of polishing mosaic elements or mosaic products.

 The specified technical result is achieved due to the fact that in a mosaic product containing mosaic elements fixed on the base, at least part of the mosaic elements is made in the form of metal plates with a thickness of 0.1-2 mm and dimensions in plan of 0.5-20 mm, coated with a glassy material, in particular enamel. The metal plates may be made of copper.

 In the case of using metal plates with a thickness of not more than 0.04 of their maximum size, a glassy material is deposited on both sides of these plates.

 The implementation of the mosaic elements in the form of pieces or plates of glassy material, for example, smalt or glass, is known, in particular, from the closest analogue, RF patent 2080008. The main difference of the proposal is the implementation of the mosaic elements in the form of metal plates coated with glassy material, in particular enamel. The enamel on each of the metal plates has a smooth surface and its own micro-volume, it refracts and reflects light in its own way. This embodiment of the mosaic elements gives the entire mosaic image a high decorativeness, depth and brightness of colors, characteristic only of enamels. The use of transparent enamels or other transparent glassy materials for coating metal plates makes it possible to obtain mosaic areas that are distinguished by the luster and color of the metal substrate, which is visible through a transparent or slightly colored coating.

 The expansion of the color palette of vitreous materials is achieved by mixing the initial powders or suspensions of various compositions, or by applying several layers of vitreous material to a metal plate.

 The relief of the surface of the mosaic element depends on the amount of vitreous material deposited on the surface of the metal plate. With an increase in the amount of this material, the surface becomes convex and even teardrop-shaped.

 The choice of the thickness of metal plates in the range of 0.1-2 mm is due to the optimal expenditure of the materials used, the dimensions of the plates in terms of 0.5-20 mm are explained by the convenience of their movement and the possibility of optimal transfer of the artistic task by mosaic technique.

 In the case where the relative thickness of the metal plates is very small, i.e. is not more than 0.04 of their maximum size, in order to prevent cracking of the vitreous material applied to them, it is practiced to apply such material also to the lower side of the plates glued to the base (the so-called enamel).

 In contrast to traditional cloisonne enamel (E. Brepol, "Art enameling", L., "Mechanical Engineering", 1986, pp. 96-102), the proposed mosaic product, which can be made of individual plates of various metals coated with multi-colored enamel of various compositions and melting points, it allows, due to the individual manufacture of mosaic elements, to exclude partitions, use materials that conflict with each other in terms of their temperature and chemical characteristics, and apply them as base materials any solid, including combustible, materials, and also to exclude operations for grinding and polishing enamel.

 Ferrous, non-ferrous metals and their alloys suitable for coating them with glassy materials can serve as a material for metal plates used for the manufacture of mosaic elements.

 To create large mosaic products, it is advisable to use plates made of carbon steel, chromium-nickel steel, cast iron with a carbon content of not more than 4%, copper. Copper plates are used in mosaic products of medium and small sizes, and in jewelry mosaics - silver and silver alloys, gold and alloys with gold, platinum.

 Copper is a very promising material for use as a basis for mosaic elements due to the high melting point of this metal, exceeding the melting point of most glassy materials used.

 As a basis for creating mosaic products any solid material can be used - wood, metals, glass, plastics. On such a base, made in accordance with the configuration of the manufactured mosaic product on a plane or volume, according to a given pattern, individual mosaic elements of the corresponding colors are attached.

 Example.

 For the manufacture of mosaic elements of a given color, several copper plates 2x2 mm in size and 0.4 mm thick, previously cut from a sheet blank, are leveled, etched, washed and dried. At the same time, a piece of low-melting enamel of the corresponding color is crushed, grinded in a metal mortar, rubbed in a porcelain mortar, cleaned of impurities and wound off in water. Then, enamel powder moistened with water in the form of a creamy suspension with a spatula is applied to the surface of several copper plates prepared in the manner described above. After that, the plates with the applied material are carefully dried and burned from below with the flame of a jewelry burner. This allows you to visually control the process and the result of firing, in which the enamel surface is smoothed and acquires a glassy sheen. The completed mosaic elements are ready for assembling the mosaic image. Further, the prepared mosaic elements of the desired colors are fixed using a binder on a rigid base in accordance with the pattern applied to it. In this case, a mosaic image is obtained by gluing copper plates of individual mosaic elements to a wooden base using BF-2 synthetic glue.

 The described technique for manufacturing a mosaic product allows you to create works of art that are closer in their color-expressive capabilities to jewelry enamels, achieving much simpler means of high compositional complexity and almost unlimited geometric dimensions.
