In the composition indicated, f-ritu H-23 of the following composition is used, wt%: odrcon 5.9; sodium silicofluoride 1.8; chalk 1.1; kaolin 5.3; sand 48.4; boric acid 23.5; soda ash 6.3; nitrate nitrate 4.8; Magnesium 2.9 (2.

The use of limestone mastic is that, due to its low elasticity, they are difficult to push through the stencil grids and give a rough mesh pattern of a grayish tint. In addition, mastics have a high melting point.

The aim of the invention is to reduce the melting temperature of the mastic and to obtain a white solid shiny pattern on the surface of the tiles.

This is achieved by the fact that the mastic for decorating ceramic tiles, which includes a FGR based on SF, transformer or petroleum jelly and a dye, contains, as the dye, the oxide oxide Rconi at the following ratio of components, wt%:

Prepare the mastic as follows: in a shredded mill they grind a frit in a wet

STANDING before passing through a sieve of 10,000 holes / cm, then they are dried to a moisture content of 0.5-1% and rubbed through a sieve of 3,600 holes / cm. The powdered frit, zirconium oxide and oil are carefully transferred and re-wiped through a sieve.

3600 resp / cm The resulting mastic is applied: on ceramic tiles by the method of pushing through the click-screen grids, stencils,

which depicted pictures. Patterned tiles are fired at 900

980C;

In tab. Figure 1 shows the mastic compositions for decoration.,

Properties mastics are given in Table. 2

From Tafm. 2, it follows that the developed compositions of the whale compared with the prototype, which is also the basic Object, have a lower firing temperature (by 30), higher whiteness (by 13%) and are characterized by a white color with a shiny coating.

The use of developed mastic will allow to produce ceramic tiles of dark tones with an ographic pattern, which will significantly widen the range of products.
