Abstract

The invention relates to methods for the production of highly artistic glassware in a by-the-go process. The purpose of the invention is to ensure the obtaining of spatial genre images on the external surface of highly artistic products. The method of producing laminated gutted glassware includes a set of opaque glass to form a jar, a set of transparent glass mass to the desired size of the workpiece, drawing a colored background from colored pretreated glass on the tubes to one caretaker. pictorial drawing of colored pre-prepared glasses on the tubes of different colors than for the background, after which the roll-in is repeated several times s plating spoev poo- transparently on glass preform and blowing. Then process the edges of the product, anneal and cool it. Colored glass for the picture rolled in metal powder fractions of not more than 2 mm.

Description

The invention relates to methods for producing decorative glass art departments and can be used in the glass industry, mainly in the field of gut production.

The aim of the invention is to improve the quality of the spatial image of the patterns when they are performed on the surface of products.

The method of producing laminated gutted glassware is carried out by setting opaque glass to form a jar, set at least one layer of transparent glass mass to form a blank, apply a colored background on its side, heat up, mechanically mix the layers, inflate, apply a beautiful pattern from the side repeat roll-in operations

heating, applying a layer of transparent glass melt and blowing, processing the edge of the product, annealing and subsequent cooling. The colored background and the pictorial pattern are pre-prepared with colored glass sets on the tubes, and for the pictorial pattern they take glasses of different tones than they do for the colored background and roll them in a metal powder with a fraction of no more than 2 mm.

Example. First, prepare a palette of colored, for example, seven pieces of glass (pieces from 12 to 20 mm can be used) smalt and pieces of milky or sulphide glass. The metal tubes are heated, onto which the opaque sulphide glass is clung, heated up until completely softened, rolled up on a metal plate and cooled. Then to another

colored glass, for example blue, is clung to the metal tube, and the same operations are repeated with it and other colored glasses.

They take a tube with sulphide glass, heat the temperature to 1200 ° C, cut it off and make a can, roll it up on a metal plate, cool it, pick up a clear glass and make a blank. Then align the walls in the katalnike and inflate. Then, on one side of the blank, two glasses, for example blue and manganese, are applied successively according to the range and pattern conceived by the author, to form a background, then the blank is guided, the workpiece is guided with a metal tool, heated, rolled and cooled. Transparent glass melt, i.e. Dip it in the stove. They roll up and inflate them again, cool them down and apply the picture conceived by the author. To do this, four colored glasses are applied from the background, for which one color is heated on the tube and rolled in metal powder, for example in bronze. Metal powders take foctions of no more than 2 mm, since with a larger size the fractions of the powder form air bubbles on the product, carried along with the powder. Then heated and applied to the background according to the intended pattern. Also come with the rest of the cerebral glasses. The whole image was put on the pattern with all colored glass, a wooden plank was pressed against the wall of the workpiece, heated to soften it, and again pressed against the plank. Once again, it is warmed up and rolled up in a wooden catalan. Then they warm up, roll up and re-inflate the billet. Clear glass melt on it

to the right size. Then inflated to the desired shape, for example flat, beat off the top of the product. The lower part of the product is transferred to another metal tube. First, heat the top of the product with a burner, and then the entire product several times until it is fully heated to a uniform temperature of the walls. Then it is cooled and transferred to heated warps for annealing the product, which is kept for 7-8 hours.

After annealing and gradual natural cooling in air for 2-3 days. the artwork of the artistic product is carried out - polished, polished, finished.

The invention makes it possible to use any glass for a jar, including opaque glass, since the image is still visible, and even in a more vibrant color palette.
