Abstract: The invention relates to the production of decorative facing materials using a glass-pelletizer and refractory filler. The inventive method for a continuous production of decorative facing slabs consists in loading of basic materials into casting-moulds which are placed on an open heat-insulated palette, and in thermal treatment in a furnace at a temperature ranging from 900° C. to 950° C. After the thermal treatment, the palette with the moulds is taken out and conditioned at an ambient temperature during 80-90 sec accompanied by cooling the surface of the slabs to a temperature ranging from 600° C. to 634° C. Afterwards, the slabs are placed in a heat-insulated closed space having a thermal resistance of walls which makes it possible to cool the surface of the slab to a temperature ranging from 100° C. to 140° C. with an average cooling rate ranging from 0.016 to 0.020 degrees/sec.
