FIELD: inorganic chemistry, in particular anti-glaze reagents.
SUBSTANCE: invention relates to production of anti-glaze reagents based on complex compounds of calcium and magnesium nitrates with carbamide of general formula xCa(NO3)2.Mg(NO3)2.(x+1).4CO(NH2)2, wherein x = (1.1-2.9). Claimed anti-glazed agent is produced by treating of calcined dolomite meal having CaO/MgO mass ratio of 1.5-4.0 and CaO+MgO sum of at least 65 mass % with non-concentrated nitric acid in solid/liquid phase ratio of 1:(2.8-4.1) followed by mixing of obtained solution with carbamide. Optionally surfactant (preferably neonol) is additionally added in amount 0.10-0.99 mass %.
EFFECT: enhances raw material base; increased productivity.
