FIELD: construction materials.

SUBSTANCE: invention relates to production of construction materials and articles, particularly, to production of face ceramic bricks of light colours. Ceramic mixture contains marl and high-melting clay in the following ratio, wt.%: marl 10–70, high-melting clay 30–90. Marl has the following mineralogical composition, wt.%: opal-cristobalite 25–45, zeolites 8–25, calcite 10–35, clay component 15–35.

EFFECT: reduction of average density, increase of frost resistance, reduction of shrinkage and sensitivity to drying, obtaining bricks of light colours and expansion of mineral raw material base for production of face bricks.
