Abstract

FIELD: polygraphic industry.

SUBSTANCE: method to manufacture filigree items may be used in the area of jewellery engineering and in the field of applied decorative art to make refined delicate items - sculptures using method of jewellery birch bark. When making filigree sculptures from birch bark, a filigree method is used - method to produce volume filigree. First the sketch of the item is made on paper, birch bark is stocked and previously treated with a thermal method until it becomes flexible, then this material is used to cut strips in the form of tapes with different width, and using method of volume filigree making, elements of future item ornament are made. The item is sculpted from clay to form a frame, the frame is dried, after drying the clay is removed from frame, then the sketched item is assembled on the frame from previously stocked elements. The assembled item is polished, coated with varnish, and its art image is finalised.

EFFECT: simplification (cheapening) of making filigree sculpture items from birch bark with preservation of their high quality and art value, while production remains non-hazardous and safe.

Description

The invention relates to the field of jewelry technology, and in particular to the field of manufacturing products by volume scanning, as well as to the field of decorative and artistic manufacturing of filigree sculptures.

Volumetric products from filigree - balls, lanterns, animal figures look very impressive and are in great demand.

Known methods for performing volume scan in the manufacture of jewelry and small-shaped products (see Scan patterns. A. Nesenenko http://nesenenko.narod.ru/BOOKS/scanj.html).

The method is as follows: the scanned pattern is drawn from traditional elements, the combination of which allows you to create a variety of ornaments. All of them are made of wire. It bends with forceps into curls, rings, squares, snakes and other figures, applying wire to a drawing on paper. The finished element is chopped off with a knife and glued to that part of the pattern along which it was curved. Always start a set with an external contour - the frame of a part or product. And then the whole pattern is gradually sealed with manufactured elements.

The set glued on paper is molded into a gypsum flask, dried and soldered from the back.

After soldering, the hot flask is thrown into the water, where the gypsum is destroyed and frees the set.

The disadvantage of this method is the complexity and harmfulness of production.

The closest prototype is a method for performing a volume scan (see Scanning patterns. A. Nesenenko http://nesenenko.narod.ru/BOOKS/scanj.html).

Volumetric products from filigree - balls, lanterns, animal figures, etc. look very impressive. They are made on a blank or made up by reamer-pattern. The ball, for example, is soldered from two hemispheres typed on a blank ball. The hemisphere set on the ball must first be molded into a flask, after which the block is removed.

The disadvantages of this method are the complexity in the manufacture of filigree sculptures and the harmfulness of production.

The purpose of the invention is the simplification (cost reduction) of the manufacture of filigree sculptural products from birch bark with the preservation of their high quality and artistic value with the safety and security of production.

The drawing illustrates the invention.

To achieve this goal in the manufacture of filigree sculptures using the volume scan method, products are made of birch bark.

Birch bark is a high-tech material, it can be embossed, weaved, burned, layered, combined into locks, etc.

Birch bark is prepared, heat treated to a flexible state, then strips in the form of narrow ribbons of various widths are cut from this material and elements are prepared from them for sculpture.

The essence of the method of manufacturing filigree sculptures is as follows: a sketch of the future product is made on paper, all the elements for it are prepared in advance from birch bark, which has undergone heat (heat) processing, since only after that any tiny elements can be cut from birch bark to make elegant (filigree) products. Details for this are bent into curls, rings, squares and other figures from traditional elements, cut out the finest details that imitate either hair or animal hair, etc.

The combination of such parts in the set with the case allows you to create not only individual figures, but also complex compositions and convey the characteristic character of images of filigree products.

For the manufacture of the frame, a blank is prepared, i.e. they mold the product in volume from clay, assemble the frame on this blank using strips of birch bark and glue, check it for accuracy of manufacturing according to the sketch, allow the clay to dry, choose a place to cut the frame so that the appearance is not disturbed, and remove clay from it, then again connect the frame at the recess. If necessary, correct and clean the frame parts if damaged.

On a prepared frame, a set of previously prepared elements is produced according to the sketch with glue. Set begins with an external circuit, and then gradually fill the entire volume with manufactured elements.

The collected product is polished, varnished and brought to the final artistic image.

Example.

The manufacture of the Elephant sculpture begins with a sketch of the artistic image on paper. They mold the figure of an elephant from clay in accordance with the sketch. On this clay form, a birch bark frame is made, they clean it. The place of the “gentle” section is determined and the clay is removed, after which the seams of the birch bark frame are glued together and the accuracy of execution is checked according to the sketch. Peel and grind again. To fill the frame with openwork, blanks of birch bark filigree elements are made, the frame is filled with openwork, they clean and grind the product, varnish and finish the product to the intended artistic image.

Claims (3)

1. A method of manufacturing filigree sculptures consists of first sketching the product, pre-preparing the material for a set of product patterns, making the frame on a blank in the shape of the product, removing the blank from the frame, restoring the frame and starting to set the frame with the prepared elements to obtain the finished product , then polished and varnished, characterized in that all the elements of the sculpture are made of birch bark, previously passed heat treatment, and the blank for creating the frame is made of clay. 2. The manufacturing method according to claim 1, characterized in that the frame can be both solid and openwork. 3. The manufacturing method according to claim 1, characterized in that the figures can be decorated or supplemented with details from any available material that allows to decorate the product or enhance the character of the created image.
