Abstract

FIELD: construction.

SUBSTANCE: in the method of production of an artistic glased ceramic product, including preparation of ceramic mass, forming, drying, the first baking, application of glasing suspension layer onto the product surface, the second baking, cooling, after application of the glasing suspension layer it is frozen by means of cooling down to the temperature of less than 0°C, then an object is used to act at the surface of the frozen glasing suspension layer, while the object is heated up to the temperature of 100-150°C and has an ornament, to get an imprint, afterwards the dry component of the glasing suspension is removed from the imprint at the temperature below 0°C, the layer is melted at the temperature of more than 0°C. According to the second version, in the method of an artistic glased ceramic product making, including preparation of ceramic mass, forming, drying, application of a glasing suspension layer onto the product surface, baking, cooling, after application of the glasing suspension layer it is frozen by means of cooling down to the temperature below 0°C, then an object is used to act at the surface of the frozen glasing suspension layer, while the object is heated up to the temperature of 100-150°C and has an ornament, to get an imprint, afterwards the dry component of the glasing suspension is removed from the imprint at the temperature below 0°C, the layer is melted at the temperature of more than 0°C.

EFFECT: simplified production of a glased ceramic product with sections, which are not coated with glasing.

Description

The invention relates to the production of ceramic art products, mainly tiles, panels, souvenirs.

A known method of producing artistic glazed ceramic products, including the preparation of ceramic mass, molding, drying, first firing, applying a layer of glaze suspension to the surface of the product, second firing, cooling [1]. To obtain on the surface of the products areas that are not covered with glaze, they are manually waxed.

The objective of the invention is to simplify the production of glazed ceramic products with areas not covered with glaze.

The technical result is achieved by the fact that according to the method for producing an artistic glazed ceramic product, including the preparation of ceramic mass, molding, drying, first firing, applying a layer of glaze suspension to the surface of the product, second firing, cooling, after applying a layer of glaze suspension it is frozen by cooling to a temperature below 0 ° C, then on the surface of the frozen layer of the glaze suspension, an object containing a pattern is heated to a temperature of 100-150 ° C until a print is obtained ka, after which the dry component of the glaze suspension is removed from the print at a temperature below 0 °, the layer is thawed at a temperature above 0 ° C.

The technical result is also achieved by the fact that according to the method for producing an artistic glazed ceramic product, including the preparation of ceramic mass, molding, drying, applying a layer of glaze suspension to the product surface, firing, cooling, characterized in that after applying a layer of glaze suspension it is frozen by cooling to temperatures below 0 ° C, then the surface of the frozen layer of the glaze suspension is exposed to an object containing a pattern heated to a temperature of 100-150 ° C until tpechatka then dry glaze slurry component is removed from the print at a temperature below 0 ° C, the layer is thawed at a temperature above 0 ° C.

Art glazed ceramic product is obtained as follows.

1. Prepare a ceramic (earthenware) mass. From the mass formed by slip casting a product (vase). The molded product is dried to a moisture content of 1-5% and fired at a temperature of 1180-1280 ° C. A suspension of glaze (white, blue, green, etc.) is prepared. The suspension layer is applied to the surface of the product and frozen by cooling to a temperature below 0 ° C, for example to -10 ° C. On the surface of the frozen layer of the glaze suspension, an object is heated by a metal rod to a temperature of 100 ° C. Moreover, in the desired areas, the moisture contained in the layer of the glaze suspension evaporates. Then, to remove dry particles of the glaze suspension from the print of the ornament, they are cleaned with a brush at a temperature below 0 ° C, the layer is thawed at a temperature above 0 ° C. After that, the product is sent to a second firing, which is carried out at a temperature of 1020-1080 ° C. The glazed product is cooled.

2. Prepare a ceramic mass on the basis of red-burning (brick) clay. From a ceramic mass, a product (panel) is molded in a plastic way. The molded product is dried to a moisture content of 1-5%. A suspension of colored glaze is prepared: blue, green, yellow, pink, brown, etc. The suspension layer is applied to the surface of the product and frozen by cooling to a temperature below 0 ° C, for example to -15 ° C. On the surface of the frozen layer of the glaze suspension heated by a temperature of 150 ° C object - a metal stamp to perform the drawing. Moreover, in the desired areas, the moisture contained in the layer of glaze suspension evaporates. Then, in order to remove the dry particles of the glaze suspension from the print, the layer is blown with compressed air cooled to a temperature below 0 ° C, the layer is thawed at a temperature above 0 ° C. After that, the product is sent for firing, which is carried out at a temperature of 970-1000 ° C. The glazed product is cooled.

When implementing the method receive a glazed art product with uncovered areas.

The proposed method is not complicated, and when glazing products with flat surfaces and using sets of dies is characterized by high performance.
