Description

The group of inventions relates to decorative art and can be used for the manufacture of jewelry and costume jewelry, including taking into account the wishes of the customer.

A known method of manufacturing inserts for jewelry made of artificial rock (RU 2320492 C1, 03/27/2008). The insert blank - artificial stone - is made from cement, crushed limestone (calcium carbonate), water, and additionally from waste from coral processing. The resulting wet mixture is placed in a metal (stainless steel) mold pre-lubricated with petroleum jelly, compacted and left for 1 day. After that, the cured preform is removed from the mold and kept in the room at room temperature for 1 month. Then the workpiece is cut into pieces, grind, polished, polished, giving it the appearance of inserts in future jewelry.

The reasons that impede the achievement of the following technical result when using the known method include technological complexity and the duration of the manufacture of the insert.

The manufacture of inserts for jewelry made of artificial stones with decorative elements (relief or line art) from fired ceramics is carried out by means of dental technology - using materials (GOST R 51735-2001 Dental ceramics. Technical requirements. Test methods), equipment and technologies used in dentistry (see, for example, VITA In-Ceram® ALUMINA. Work instruction. Production of the frame using slip technology. Date of issue: 03-06).

Inserts to a jewelry product, depending on the type of decorative element - a relief or line art - are made in various ways and are explained by the following examples.

1. Production of an insert with a relief image of a decorative element in the form of a copy of intalia.

On the impression mass, for example, of silicone or alginate impression material, an impression is made, gems, for example, of the original intalia (Fig. 1 - Agatop. Male portrait. Between the 2nd century BC and the 1st century AD Ancient Rome . Archaeological Museum. Florence) or cameos (figure 2 - Bust of Diana de Poitiers. Mid XVI century. France).

A duplicate ring is set on the cured impression mass with a gem print; it sets the shape and dimensions of the produced copy of the gem.

In the order and proportions recommended by the manufacturer (VITA Zahnfabrik N. Rauter GmbH & Co.KG), a slip uniform is prepared from a powder of dental non-metal ceramic (VITA In-Ceram® ALUMINA) and mixing liquid (VITA In-Ceram® ALUMINA / ZIRCONIA) consistency and fill them with an impression impression with a given layer thickness.

After the slip has hardened, the blank of the insert with a decorative element is removed from the impression mass, placed in the VITA INCERAMAT dental oven and the blank is cured by drying and firing in the recommended time and temperature mode.

After cooling the workpiece, the surface of the decorative element - copies of the gem - is covered with a layer of a liquid mixture of powder of a transparent pigmented enamel ceramic (see clauses 3.1.4, 3.1.5 and 3.1.7 GOST R 51735-2001) with water and final drying is carried out and firing the insert blank in the recommended time and temperature mode with the formation of an enamel coating of the decorative element.

If necessary, mechanical processing of the seat of the manufactured insert to a specific jewelry product is performed.

2. Production of an insert with a line image of a decorative element, for example, in the form of a zodiac sign or monogram (monogram).

In the order and proportions recommended by the manufacturer, a slip of a homogeneous consistency is prepared from a powder of non-metal ceramic ceramic and mixing liquid and a crucible is poured with a predetermined configuration and size corresponding to the manufactured artificial insert stone.

While the workpiece material is in a plastic state, a decorative element is applied to the front surface of the workpiece - a line drawing with a pointed object or, preferably, with a stamp.

The crucible with the workpiece is placed in a dental oven and the insert blank is cured with a decorative element by drying and firing in the recommended time and temperature mode.

After the workpiece is cooled, a layer of a liquid mixture of the powder of transparent pigmented enamel ceramic with water is applied to the surface of the decorative element, the line pattern is filled with recesses in the line image and final drying and firing of the insert blank is carried out in the recommended time and temperature mode to form the enamel coating of the decorative element.

If necessary, mechanical processing of the seat of the manufactured insert to a specific jewelry product is performed.

At the request of the customer, the decorative element - line drawing - can have an exclusive character - the customer’s zodiac sign, for example, as shown in figure 2 (the Aries zodiac sign) or monogram (monogram) as shown in figure 3 [Monogram on the memorial ruble 1841 Composed of the letter "M" (Maria) and the letter "A" (Alexander)].

Against the general colored background of the decorative element, areas of the relief image or indented strokes of the decorative image elements of the insert are highlighted in darker color, above which there is a thicker layer of colored enamel, thereby providing artistic activation of the image.

Thus, it can be seen that the above information confirms the possibility of simplifying the technology of applying decorative elements in the manufacture of inserts for jewelry, expand their range, including taking into account the wishes of customers in the manufacture of exclusive products.
