The invention relates to the manufacture of ceramic products, in particular a single author's works: souvenir, "Easter eggs".

Known methods for producing ceramic products, comprising preparing a ceramic body, formed by casting in a plaster mould, drying, calcination [1, 2]. Using these methods, it is difficult to obtain a hollow thin-walled ceramic product in the form of "eggs".

The objective of the invention is to obtain a hollow thin-walled ceramic products in the form of "eggs".

The technical result is achieved by the method for producing art pottery "egg", including the preparation of the ceramic material, applied on the forming surface, drying, calcination, as the forming surface using intact eggshells with remote content. On the surface of the eggshell put a layer of plaster dough thickness 0.5-1.5 mm

In the egg (e.g., chicken, goose, ostrich), without destroying the shell, perform the hole diameter of 1-2 mm and through him remove the contents, washed and dried. In the hole insert a thin metal wire. On the surface of the eggshell put a layer of plaster dough thickness 0.5-1.5 mm and kept it until the end of the seizure. You can powder gypsum with water-dampened surface I is offered by the shell. Prepare ceramic weight (for example, porcelain slip) humidity 32-42% and put it on the surface of the egg shell by spraying or dipping. After reaching the desired thickness of the ceramic body (e.g., 2-3 mm) the future of the product dried to a moisture content of 18-20%, the metal wire carefully removed from the hole, then the product is finally dried to a moisture content of 1-2% and burn in mode suitable for the selected ceramic material. When the firing is carried out at high (800-1250°C) temperatures, eggshell "fade", a thin layer of plaster test under the influence of the processes of dehydration is destroyed. Gaseous decomposition products of the egg shell and plaster dough out through the hole. Ceramic "egg" can be covered with a layer of glaze, painted ceramic, luster paints, drugs, precious metals by conventional technologies.

Obtained by the proposed method and the ceramic "egg" is uniqueness, originality and artistic expression.

FIELD: technology for producing ornamentation or marking in form of surface structure on a widely used object in form of a bowl, mug or cup, made of glass or glass-like material and having glazed surface at least in some zones as supporting surface.

SUBSTANCE: in accordance to invention, glazed surface in the zone where marking or decoration is going to be applied has practically equal properties across whole surface. Decoration or marking is applied by imprinting characteristic surface with quartz solution by means of printing method to equalize the surface with shape or configuration of decoration or marking after quartz solution solidifies. Invention also describes method for manufacturing surface structures on widely used object having glass or glass-like wall. Decoration is produced as a result of application of quartz solution, distributed in limited given manner in direction of surface along characteristic surface or inside it, and glazed surface is evened out in accordance to decoration configuration after solidification of quartz solution so that surface becomes transparent.

EFFECT: simplification of method for decorating widely used items.
