FIELD: construction materials.SUBSTANCE: invention relates to a method for producing a glazed brick, including the preparation of an glaze mass, its fritting, grinding the frit, mixing with water, applying a layer on at least the front part of the brick and firing, differs in that it uses a glaze mass having the following composition, wt. %: zeolite, fractions – 0.16 mm – 36–54 %; NaOH – 5–20 %; NaBO– 5–15 %; KOH – 5–15 %; silica fume – 1.2–3.2 %, superplasticizer C3 – 0.3–0.8 %, water 18–25 %. Finished mixture is fritted with 2-hour exposure at a temperature of 950–970 °C, the resulting melt is granulated into water, the granules are ground in water to a fraction of 0.08 mm, then the glaze is applied on raw brick and calcined at a temperature of 950–970 °C. Glaze is applied to raw brick by spraying with compressed air at a pressure of at least 5 atm or applying it to a brick with a layer, after mixing the glaze with white glue in a 4:1 ratio.EFFECT: technical result – reduced firing temperature of the glaze to the lower limits of the firing temperature of the brick and reduced duration of the molding.1 cl, 3 ex
