FIELD: ceramic industry.
SUBSTANCE: invention relates to technology of silicates and ceramic mixtures for making brick. Ceramic mixture for making bricks contains, wt%: clay 81.7-86.3; quartzite 12.0-16.0; wollastonite 0.2-0.3; kaolin 1.0-1.5; saponified rosin 0.2-0.3; dry peat 0.2-0.3. Bricks are formed by plastic method, dried to the moisture content of not more than 6 % and annealed at the temperature of 980-1,020 °C.
EFFECT: technical result is higher frost resistance of bricks made from ceramic mixture.
