The aim is to make the glaze, including 5 Fe-jO, CaO, Mgo, .KjQ, the indicated components, amounts, wt.%: SiO 48.33-54.25 AejOi 12.74-19r-12, 2.08-2, 16 CaO 12.50-22.87 MgO 0.6 D), 89 2.40-3.24 KjO2.51-3.52 6503 4.40-8.39 The following raw material Clay5-17 Latholite concentrate is used for the preparation. ZO-56 Mariupolitic wastes39-53 A positive effect is achieved due to the introduction into the charge composition of the frit glaze of chemical and metallurgical wastes - mariupolitic wastes of the following composition, wt.%: S 0 0i 58.69 CaO2.50 5050.03 APjO 20.50 Mg: o1.05 nnn2.12 fe / iO 1.88 .18 FeO2.08 5.89 Availability in Mariupol Nepheline, aegirine, and albite grades allow it to be used as a complex raw material of CL glaze, since the above mineral phases are favorable for melt formation at lower calcining temperatures and creating an glaze coating with enhanced physical and mechanical properties. The preparation of the glaze is carried out in a known manner without prior fritting. Grinding of the charge materials- "materials" is carried out in ball mills of the residue on the sieve 0056-0.1-0.3%, imoi ,, glazing suspension 1.48-1.54 g / cm. Glaze is applied to the product by watering or spraying with both single and double firing. At a firing temperature of 920-960 C, the glaze is well spread on the product, it has a tight adhesion to the base, КТР (6,326, 64). Example 1. In a ball mill load 50 g of clay, 560 g of datolite concentrate, 390 g of mariupolite waste, pour 1 l of water. The resulting glaze has the following composition, wt.%: Sia / z 48.33 NoizO 2.4O AbgOz 12.74 202.51 CaO 22.87 Fe70 2.16 0.60 BjO 8.39 EXAMPLE 2.

The proposed glaze is advantageously different from the basic composition, since it does not require pre-friting of the raw material, has a lower temperature and a shorter roasting time.

The glaze of the proposed composition is characterized by shorter roasting time, greater frost resistance, has a wide temperature range of roasting while maintaining low CTE, which provides high heat resistance and good consistency with curved units. Low temperature Pla The invention does not require full-scale firing regimes in modern population capital costs, such as 5 automated flow-conveyor belts.
