The invention relates to ceramic sawing and can be used in the manufacture of facade and veneer tiles. Ceramic mass 1 for making tiles is known, including the following components, wt%: Clay 25-40 Quartz sand 10-25 Phosphoric slag production 20-45 Tile slaughter 3-6 Nepheline concentrate 10-30 Ceramic mass for tile preparation is closest to the one proposed includes the following components, ve ,. %: Clay23-43 Alkaline fluorescent feldspar22 Chromite ore 5 Ash - heat power engineering 30-50 In addition, the composition can enter the battle of products (9 weight parts) and chamotte (4 weight parts) 2. However, tiles obtained from known ceramic masses are characterized by low strength and thermal resistance, as well as high absorption. The purpose of the invention is to increase the spiciness, heat resistance and reduction in the additional absorption of the tiles.

The table indicated is achieved; The fact that the ceramic mass for the manufacture of tiles, mainly facade and cladding, including clay, fireclay, alkali-containing flux and waste of heat-and-power engineering, contains ash-and-slag mixture and, additionally, quartz sand as waste heat-power engineering in the following ratio of components, wt.%: Clay30-40 Chamot5- 10 Fluffy flux 5-10 Ashes and slags mix 30-55 Quartz sand 5-10 Ashes: slag ratio in the ash-and-slag mixture 1: 1-1: 2. The addition of an inert material with a basicity modulus M (s-0.1 and a silicate modulus of 1.3-3.3.2 Mg, as well as quartz sand to the composition of the ceramic mass of the ash-slag mixture allows increasing the strength and heat resistance of the tiles, as well as reducing their water absorption The mass is prepared according to the slip processing technology. The slip is removed and samples are pressed from the press powder at a pressure of 100-120 atm. Drying the wire for 10 minutes followed by high-speed firing at 1020g1040s for 21 minutes Table 1 shows the composition of the proposed mass.
