FIELD: foundry, possibly manufacture of casting cores in heated fitting. SUBSTANCE: method of making casting cores from wet sand-resin mixtures comprises steps of adding into mixture acid metal salts and molding wood-chemical modifying agent in quantity 0.02-0.08 mass%; heating fitting. Addition of molding wood-chemical modifying agent directly to refractory filler provides uniform distribution of modifying agent in mixture. EFFECT: significantly enhanced strength of casting cores. 2 tbl
